RK3588 Custom AI Model Deployment, WF-C3588-N6, AndroidSBC, Sao Paulo

TL;DR: RK3588 Custom AI Model Deployment

SHENZHEN, China, September 12, 2026 - Wanlin Longgang released a 25,590-unit WF-C3588-N6 lot for Sao Paulo, Brazil this week, the 221st run booked against the Rockchip RK3588 allocation.

AndroidSBC opens regional OEM partner slots on the custom RK3588 motherboard family serving Sao Paulo, Brazil. The WF-C3588 line is a custom motherboard programme built on the Rockchip RK3588 octa-core platform (4x Cortex-A76 at 2.4GHz plus 4x Cortex-A55 at 1.8GHz on 8nm) with a triple-core NPU delivering 6 TOPS of INT8 inference, 8K H.265 decode and up to 32GB of LPDDR4X or LPDDR5. AndroidSBC, the export arm of Wanlin Manufacturing Group, builds nine custom variants at the Longgang source factory in Shenzhen for Sao Paulo and Brazil buyers: WF-C3588-A0 custom Android motherboards, WF-C3588-I1 custom industrial boards, WF-C3588-M2 core boards and SOMs with carrier design, WF-C3588-S3 custom signage and video wall boards, WF-C3588-K4 custom kiosk and POS boards, WF-C3588-R5 custom robotics controllers, WF-C3588-N6 custom NVR boards, WF-C3588-E7 custom edge AI boards, and WF-C3588-P8 custom ARM PC and NAS boards.

About AndroidSBC and the Rockchip RK3588 Board Family

The WF-C3588 exists because Brazil buyers kept asking one supplier for two different custom board tiers. Wanlin Manufacturing Group answered by putting nine custom variants on the same Rockchip RK3588 octa-core silicon with 6 TOPS NPU, 8K H.265 video and up to 32GB of LPDDR5. The group runs SMT, burn-in and pre-compliance testing in one Longgang building in Shenzhen, and the export desk holds the certification file rather than passing it back to the importer. For a Sao Paulo distributor that means one vendor file, one document format and one MOQ structure across the custom variants it sells.

WF-C3588-N6 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-C3588-N6 (Custom NVR and Security Surveillance Board) holds its display output and its decoder load at the same time through the burn-in loop, a combination that the legacy boards in the comparison column cannot sustain. For Brazil importers sourcing the WF-Series, the 16GB + 128GB (WF-C3588-N6-C) variant is the typical configuration for the custom NVR and surveillance programmes use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.

Challenges in Sourcing Custom NVR and Security Surveillance Board for Brazil Buyers

The recurring problem for Sao Paulo and Brazil buyers sourcing a custom nvr and security surveillance board is not the headline unit price, it is whether the allocation actually holds. The Rockchip RK3588 needs its own wafer slot, and brokers who quote from stock frequently cannot honour that slot once a 25,590-unit push lands mid-quarter. The software question follows immediately. The hardware spec sheet is easy to verify; the difference between a board that runs a launcher and a board that holds a certified, credential-locked stack only becomes visible after the first field update.

Documentation closes the list. Buyers in Sao Paulo have learned to ask for the test reports before the deposit, because a CE mark printed on a carton is worth nothing at the port without the Declaration of Conformity behind it. AndroidSBC handles it by doing the custom I/O build, the software burn and the documentation at the factory: every lot leaves Longgang with the certified image loaded, a unit-level burn-in barcode, and a Technical File that carries the test reports. The nine WF-C3588 custom variants cover smart NVRs, multi-camera recorders, face recognition terminals, access control, turnstile controllers, intercom stations, LPR cameras, perimeter systems, and behaviour analytics with three memory configurations each, which means a Sao Paulo integrator can usually match a customer requirement without a bespoke production run.

Compliance for Brazil is handled at the factory rather than after arrival. In Brazil ANATEL homologation is a precondition for customs release, and the homologation holder is normally a local legal entity separate from the overseas manufacturer. The Longgang export desk builds the destination-market file for ANATEL homologation with INMETRO safety conformity administered by ANATEL and issues it alongside the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), with the shipment booked into Port of Santos on the Santos to Shanghai lane.

Competitive Comparison: WF-C3588-N6 vs Competing RK3588 Boards

Three groups of board compete for the custom nvr and security surveillance board socket. The first is catalogue silicon sold on price with no customization route and no certification file. The second is re-badged stock where the seller cannot produce a schematic or a test report. The third is a genuine custom platform on Rockchip RK3588 with the engineering desk, the burn-in rack and the certification file in one Longgang building. The WF-C3588-N6 sits in the third group.

• vs generic NVR chipsets: the WF-C3588-N6 carries the analytics on the 6 TOPS NPU, so the recorder does not ship a cloud subscription as a hidden dependency.
• vs PC-based recorders: a fanless board replaces a workstation-class recorder and survives gate cabinets and outdoor enclosures.
• vs camera-side AI splits: one board class covers the NVR, the face terminal and the turnstile, which simplifies spares and firmware across one estate.
• vs unbranded surveillance boards: the per-lot file and the burn-in record are what an installer needs when a perimeter line has to answer for uptime.

Global Custom NVR and Surveillance Board Market Trends

The Custom NVR and Surveillance Board market is the frame that decides how Brazil importers time their custom nvr and security surveillance board orders. The figure most Brazil buyers quote when they argue about allocation is the Edge AI hardware segment, which MarketsandMarkets sizes at USD 26.9 billion in 2025 with a 32.7 percent CAGR to USD 108.2 billion by 2030 (MarketsandMarkets, Edge AI Hardware Market Report, 2025-2030); it is the public proxy for the RK3588-class silicon that custom board buyers compete for, not a forecast for this category. For Sao Paulo, three buying patterns are shaping the WF-C3588 order book:

• City surveillance NVR: a municipal programme records and analyses sixteen channels per node on a fanless board.
• Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-C3588-N6 board carries that headroom without a board change.
• License plate recognition gate: a parking operator pairs LPR on the NPU with relay control for the barrier.

For the Custom NVR and Surveillance Board category the practical signal in Brazil is that framework agreements are replacing spot buying, and the agreements are getting longer.

In all three cases, Sao Paulo buyers are converting spot quotes into blanket orders with a monthly lot release, because a custom motherboard programme that has to hold a twelve-month shipping window cannot tolerate a mid-year allocation break.

Partner Success Story: Cedarline Media Networks in Sao Paulo, Brazil

Cedarline Media Networks, a DOOH network operator serving the Brazil market, deployed 8,400 custom WF-C3588-S3 video wall boards for a control room and street network. The rollout covered the city surveillance nvr, license plate recognition gate, and retail loss prevention workloads, with AndroidSBC handling the burn-in, the certification scope, and the palletisation at the Wanlin Longgang plant.

• Deployed: 8,400 custom WF-C3588-S3 video wall boards for a control room and street network
• Region: Sao Paulo, Brazil
• Models used: WF-C3588-N6 (lead SKU), plus eight sibling custom RK3588 board variants in the same platform family
• Certifications handled: CE, FCC, UKCA, RoHS, REACH, IEC 62368-1, EN 55032, EN 55035, plus optional UL 60950-1, GMS, Widevine L1 and Dolby Audio per variant

Field Report: burn-in room at the Wanlin Longgang plant running a 72-hour continuous loop on 25,590 units of the WF-C3588-N6 board, with rack-wide output monitored by an automatic pattern checker

Reporter Lin Yu, on the ground in Sao Paulo, Brazil. The burn-in room runs pattern generators that alternate between HDR10 and HLG material. Each WF-C3588-N6 unit carries a barcode tracked across the full 72-hour loop, and the rack controller issues a remote reboot whenever a unit shows an intermittent response on the I/O header.

The engineering desk ran a firmware re-flash drill on three units to confirm the recovery path a field technician would use.

The inspection confirmed three things on the spot: the WF-C3588-N6 units hold the burn-in with a yield above 99.35 percent, the loaded firmware image survives a 72-hour continuous loop without credential drift, and the pallets carry the matching certification file for the destination market, covering ANATEL homologation with INMETRO safety conformity administered by ANATEL, cleared for entry at Port of Santos on the Santos to Shanghai lane. Wanlin remains one of the few source factories currently shipping a nine-variant custom RK3588 motherboard line with a per-lot paper trail that Brazil importers can hand straight to their customs broker.

WF-C3588-N6 Application Scenarios

The WF-C3588 line fits nine custom motherboard lanes, with the WF-C3588-N6 (Custom NVR and Security Surveillance Board) as the lead SKU for Sao Paulo and Brazil programmes:

• City surveillance NVR: a municipal programme records and analyses sixteen channels per node on a fanless board.
• Face recognition terminal: a corporate lobby runs face-based entry with the camera and the reader bank on one multi-serial profile.
• License plate recognition gate: a parking operator pairs LPR on the NPU with relay control for the barrier.
• Perimeter detection site: a critical facility runs behaviour analytics at the fence line with local alarm relay.
• Building intercom station: a property network runs door stations on the wide-temperature variant outside the lobby.
• Retail loss prevention: a chain correlates POS events with camera analytics on the same recorder board.
• Turnstile controller: a stadium estate drives turnstiles and readers from the same board family as its recorders.
• Construction site security: a contractor deploys sealed NVRs with 4G failover where no cabling exists.

Partnership Models for Sao Paulo Buyers

AndroidSBC runs three engagement tiers for Brazil importers and brand owners sourcing a custom nvr and security surveillance board on the WF-C3588 custom line:

• OEM (your brand on our hardware): custom logo silk-print, custom packaging, custom boot animation, custom SKU label, and a private-label certification file.
• ODM (your spec on our reference design): schematic and stack-up review, carrier or motherboard redesign, custom firmware features, and a BSP port handled by the Longgang engineering desk.
• Distribution (your channel, our stock): regional distributor rights, channel rebate, stock holding at the factory, and a framework agreement with a monthly lot release.

Every tier draws on the same Longgang line and the same certification desk. A Sao Paulo first order on the WF-C3588-N6 normally lands on the 16GB + 128GB (WF-C3588-N6-C) configuration at MOQ 5,000 units per shipment, with standard samples in 1-3 days and a 15-30 day mass-production window on custom builds.

Frequently Asked Questions

What exactly can be customised on an RK3588 motherboard from AndroidSBC?

Answer: Everything from the copper up. Custom PCB and PCBA, custom I/O routing, custom memory and storage configuration, custom display and camera interfaces, custom thermal profile from commercial to -40C to 85C industrial, and custom branding including silk-printed logo, packaging, SKU label and boot animation. The firmware side covers custom Android (GMS or AOSP), Ubuntu, Debian, Yocto and OpenHarmony builds with BSP ports handled by the Longgang engineering desk rather than handed to the buyer as an unmodified vendor drop.

Can AndroidSBC port a custom Android ROM or a custom Linux BSP to our carrier board?

Answer: Yes, and that work stays in-house. The ODM tier covers custom Android ROM builds with proprietary services and launchers, AOSP builds without Google services, and Linux images on Ubuntu, Debian, Yocto or Buildroot. BSP ports for custom carrier boards are executed by the Longgang engineering desk, with SDK and BSP source released to the partner under NDA. The same desk handles driver development for the I/O you added, which is the part that usually stalls when a factory forwards a vendor drop and walks away.

Can the 6 TOPS NPU on a custom board run our own AI models?

Answer: Yes. The RK3588 NPU runs INT4, INT8, INT16, FP16, BF16 and TF32, and AndroidSBC supports model deployment through the Rockchip RKNN-Toolkit2, with quantization from PyTorch, ONNX, TensorFlow, Caffe and MXNet. As part of the ODM tier, the engineering desk walks your model from framework to RKNN format and validates it on the actual board configuration you are shipping, not a reference unit. Model files are versioned so a retrained model can be pushed to field units through OTA without a board swap.

What are the MOQ and lead times for a custom RK3588 motherboard?

Answer: The structure is deliberately two-speed: 1-3 days for a standard-variant sample so a Brazil project team can start immediately, and 15-30 days to mass production on a custom run once the design freezes. MOQ is 5,000 units per shipment on standard variants, with custom and pilot quantities negotiated against the annual volume commitment.

What certifications does a custom board need for Brazil, and who handles them?

Answer: Certification is part of the customization scope, not an afterthought. The in-house file covers CE, FCC Part 15, UKCA, RoHS 2.0, REACH and IEC 62368-1 with test reports dated inside twelve months, plus GMS and EDLA tracks for custom Android and display products. The file is built for the exact configuration you ship, which matters for a custom board because a test report on a different memory fit is not a valid report at all.

How long will AndroidSBC keep supplying a custom board?

Answer: Seven years minimum, written into the framework agreement. The RK3588 platform carries a long industrial lifecycle, and Wanlin commits to the supply window, to security patches across the Android, Ubuntu LTS, Debian LTS and Yocto tracks, and to OTA update infrastructure for field-deployed units. For a custom board that is the whole point of going to a source factory: the product lifecycle is a contract term, not a hope.

Can AndroidSBC ship custom boards to Amazon FBA warehouses or 3PL consolidation points?

Answer: That is routine. AndroidSBC delivers DDP into Amazon FBA in the US, EU and Japan and into 3PL consolidation points at Hong Kong, Singapore, Rotterdam, Los Angeles and Shenzhen. Carton and pallet configuration follows FBA inbound rules, and the place of origin on the declaration is the Wanlin Longgang source factory.

How does AndroidSBC handle RMA or DOA replacements on custom boards?

Answer: Target DOA is 0.3 percent across twelve months. RMA works by returning the WF-C3588-N6 unit to Longgang with its burn-in barcode; replacements ship inside ten business days. Since each unit is traceable to its burn-in and configuration record, partners typically receive a root-cause note with the replacement rather than a silent credit.
