RK3588 PCIe 3.0 Custom Expansion Board, WF-C3588-R5, AndroidSBC, Sao Paulo

TL;DR: RK3588 PCIe 3.0 Custom Expansion Board

LONGGANG, Shenzhen, September 12, 2026 - Wanlin Manufacturing Group confirmed the release of lot 267, a 7,030-unit run of WF-C3588-R5 boards destined for Sao Paulo, Brazil, after the lot cleared the burn-in rack and the pre-shipment bench.

AndroidSBC releases the WF-C3588 custom board family for global custom-motherboard sourcing serving Sao Paulo, Brazil. What Brazil importers get from the WF-C3588 programme is a single Rockchip RK3588 silicon across nine custom motherboard variants, all built at the Wanlin Longgang plant in Shenzhen. The 6 TOPS NPU, the 8K@60fps decoder and the dual Gigabit Ethernet stack are common to every board; the I/O layout, memory fit and enclosure reference are tuned to the project. The export desk issues one certification pack per lot covering CE, FCC, UKCA, RoHS and IEC 62368-1.

About AndroidSBC and the Rockchip RK3588 Board Family

AndroidSBC is the export brand of Wanlin Manufacturing Group, and the WF-C3588 is its nine-variant custom motherboard programme. Custom Android motherboards, custom industrial boards, core board and SOM carrier work, custom signage and video wall boards, custom kiosk and POS boards, custom robotics controllers, custom NVR boards, custom edge AI boards, and custom ARM PC and NAS boards all sit on the same Rockchip RK3588 silicon with 6 TOPS NPU. The Longgang plant in Shenzhen runs its own SMT lines, aging racks and EMC pre-compliance bench, so the export file is produced where the boards are built. For Brazil importers that removes the usual gap between the factory that makes the custom board and the party that has to answer for it at customs.

WF-C3588-R5 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-C3588-R5 (Custom Robotics and AGV Control 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 8GB + 32GB (WF-C3588-R5-B) variant is the typical configuration for the custom robotics controller programmes use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.

Challenges in Sourcing Custom Robotics and AGV Control Board for Brazil Buyers

Buyers in Sao Paulo who have run the custom robotics and agv control board category for a few years tend to stop shopping on price alone. The Rockchip RK3588 allocation is the real constraint, and it is the reason a 7,030-unit order can look cheap on paper and expensive in a slipped quarter. Then comes the firmware question. The hardware spec is straightforward to verify; whether the board holds a credential-locked stack through a 72-hour loop and a field OTA is a different test, and it is normally the Sao Paulo buyer's warehouse that discovers the answer.

Documentation is the third item on the list. A CE mark without a matching Declaration of Conformity and Technical File is not a marking problem, it is a customs problem, and it tends to surface after the goods are already on the water. AndroidSBC's approach is to close the gap at the factory gate. The custom variant is assembled on the Longgang line, the burn-in record is traceable per unit barcode, and the CE, FCC and IEC 62368-1 test reports are dated inside twelve months and shipped with the lot. The nine WF-C3588 variants span AGV controllers, AMR mainboards, service robots, inspection robots, quadruped platforms, SLAM navigation, robot vision, fleet dispatch terminals, and charging stations, with three memory configurations per variant for Sao Paulo buyers who need a standard custom SKU rather than a from-scratch build.

For Brazil specifically, the file travels with the goods. 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. AndroidSBC prepares the ANATEL homologation with INMETRO safety conformity documentation for ANATEL, attaches the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), and consigns the lot to Port of Santos on the Santos to Shanghai lane.

Competitive Comparison: WF-C3588-R5 vs Competing RK3588 Boards

Three families of board chase the same custom robotics and agv control board socket. The first is catalogue hardware with fixed memory and fixed I/O, the second is re-badged stock where nobody owns the schematic, and the third is a real custom platform built by the factory that runs the SMT line. The WF-C3588-R5 belongs to the third family and separates itself on Rockchip RK3588, on customization depth from schematic to firmware, and on a certified image burned per lot.

• vs paired PC-plus-MCU controllers: the WF-C3588-R5 runs vision, navigation and fleet logic on one board and hands only the power stage to the drive electronics.
• vs generic SBC robot builds: the CAN, multi-serial and real-time options come validated on the reference carrier instead of being patched in by the integrator.
• vs cloud-vision robots: SLAM and obstacle detection stay on the 6 TOPS NPU, so the robot keeps navigating when the warehouse WiFi drops.
• vs module resellers: custom I/O changes are executed by the Longgang engineering desk with the test bench that will validate them.

Global Custom Robotics Control Board Market Trends

Buyers in Sao Paulo are reading the Custom Robotics Control Board curve before they commit to a custom robotics and agv control board programme. MarketsandMarkets reports the Edge AI hardware segment at USD 26.9 billion in 2025 with a 32.7 percent CAGR to USD 108.2 billion by 2030 (MarketsandMarkets, 2025-2030), used here as the RK3588-class silicon baseline rather than as a number for this category. That baseline breaks into three practical demand patterns for the WF-C3588 in Brazil:

• Warehouse AGV fleet: an automation vendor runs SLAM and fleet dispatch on the board with dual GbE back to the coordinator.
• Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-C3588-R5 board carries that headroom without a board change.
• Inspection quadruped: a platform maker runs gait control and inspection vision on isolated cores under PREEMPT_RT.

Analysts covering the Custom Robotics Control Board space point to the same pattern in Brazil: order books are being built around platform breadth rather than a single part number.

The common thread in Brazil is that single orders are being replaced by blanket agreements with a monthly release, because a custom board programme that has to survive a twelve-month window cannot absorb an allocation gap in the middle of it.

Partner Success Story: Meridian Kiosk Systems in Sao Paulo, Brazil

Meridian Kiosk Systems, a self-service kiosk manufacturer serving the Brazil market, deployed 6,300 custom WF-C3588-K4 kiosk boards for an ordering-terminal estate. The rollout covered the warehouse agv fleet, inspection quadruped, and agriculture robot workloads, with AndroidSBC handling the burn-in, the certification scope, and the palletisation at the Wanlin Longgang plant.

• Deployed: 6,300 custom WF-C3588-K4 kiosk boards for an ordering-terminal estate
• Region: Sao Paulo, Brazil
• Models used: WF-C3588-R5 (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
• Logistics: FOB Yantian with the Wanlin Group Longgang source factory named on the export declaration, entering Port of Santos via the Santos to Shanghai lane

"The kiosk ROM was the difference. Locked launcher, our APK pre-installed, payment profile signed at the factory. Our field failure rate halved because the board arrives as a finished terminal brain, not a dev kit wearing a label."

- Camila Fuentes, Operations Lead

Field Report: burn-in room at the Wanlin Longgang plant running a 72-hour continuous loop on 7,030 units of the WF-C3588-R5 board, with rack-wide output monitored by an automatic pattern checker

Reporter Wei Tao, on the ground in Sao Paulo, Brazil. The burn-in room runs pattern generators that alternate between HDR10 and HLG material. Each WF-C3588-R5 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 line ran the WF-C3588-R5 boards through a 30-minute HDR10 loop at the inspection bench with no colour banding reported by the operator.

The inspection confirmed three things on the spot: the WF-C3588-R5 units hold the burn-in with a yield above 99.06 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-R5 Application Scenarios

The WF-C3588 line fits nine custom motherboard lanes, with the WF-C3588-R5 (Custom Robotics and AGV Control Board) as the lead SKU for Sao Paulo and Brazil programmes:

• Warehouse AGV fleet: an automation vendor runs SLAM and fleet dispatch on the board with dual GbE back to the coordinator.
• AMR delivery robot: a service robot pairs NPU navigation with a custom carrier that routes the sensor stack.
• Inspection quadruped: a platform maker runs gait control and inspection vision on isolated cores under PREEMPT_RT.
• Cleaning robot fleet: a facility operator runs coverage planning and obstacle detection locally with nightly model updates.
• Charging station control: the board coordinates dock sequencing, battery telemetry and fleet handshakes.
• Agriculture robot: a field robot runs row detection on the NPU offline, kilometres from the nearest access point.
• Remote monitoring link: a fleet operator streams diagnostics over the optional 5G seat to a central depot.
• Robot vision retrofit: an older fleet gains NPU vision without replacing the drive electronics.

Partnership Models for Sao Paulo Buyers

The WF-C3588 custom line is available to Brazil partners through three routes, and they can be mixed inside one agreement:

• 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.

Whichever structure a Brazil partner selects, the lot leaves Longgang with the same certification pack and the same test flow. The standard entry point on the WF-C3588-R5 is the 8GB + 32GB (WF-C3588-R5-B) configuration at MOQ 5,000 units per shipment, 1-3 days to sample and 15-30 days to mass production.

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. Custom NPU development covers RKNN model deployment, quantization from the major frameworks, multi-model pipelines on the triple-core NPU, and custom AI algorithm integration. The desk validates throughput on your exact memory configuration, and the deployment lands as a versioned RKNN file that OTA can update in the field, which is how Brazil partners iterate models without replacing hardware.

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: The DOA target is 0.3 percent over twelve months. For RMA, partners send the WF-C3588-R5 unit back to Longgang with the burn-in barcode attached, and replacements go out within ten business days. The per-unit record means the failure report usually carries a root cause alongside the replacement, which is what a Brazil integrator running a custom configuration actually needs.
