TL;DR: RK3588 Custom Android Industrial Board

Sao Paulo, Brazil - September 12, 2026. Wanlin Longgang confirmed lot 129 this week: 10,510 WF-C3588-P8 boards for Sao Paulo, Brazil, released with the per-lot certification pack and a unit-level burn-in record.

AndroidSBC manufacturer capacity statement from the WF-C3588 custom board production base serving Sao Paulo, Brazil. One Rockchip RK3588 silicon, nine custom motherboard variants. The WF-C3588 programme covers custom Android boards, industrial control, core board and SOM work, signage, kiosk and POS, robotics, NVR, edge AI and ARM PC lines, all on the same octa-core 8nm platform with 6 TOPS NPU. Every board leaves the Wanlin Longgang plant with a per-lot certification pack and a burn-in record traceable by unit barcode. Buyers in Sao Paulo and Brazil can mix custom variants inside a single framework agreement.

About AndroidSBC and the Rockchip RK3588 Board Family

AndroidSBC is the export brand of Wanlin Manufacturing Group. The group runs SMT, test and packing under one roof at Longgang in Shenzhen, and it has built custom boards on Rockchip silicon for overseas OEM customers for over ten years. The WF-C3588 line-up covers nine custom categories on the same Rockchip RK3588 octa-core 8nm silicon with 6 TOPS NPU: custom Android motherboards, custom industrial boards, core board and SOM carrier design, 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. Buyers in Sao Paulo and Brazil can source any of the nine custom variants from one factory with one set of export documents.

WF-C3588-P8 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-C3588-P8 (Custom ARM PC, Mini PC and NAS 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 + 256GB (WF-C3588-P8-C) variant is the typical configuration for the custom ARM PC and NAS programmes use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.

Challenges in Sourcing Custom ARM PC, Mini PC and NAS Board for Brazil Buyers

Buyers in Sao Paulo who have sourced a custom arm pc, mini pc and nas board for a few seasons tend to separate two questions: can the factory hold the price, and can it hold the allocation. The second one is harder. The Rockchip RK3588 is allocated at wafer level, and a 10,510-unit order placed against trader stock is the order most likely to slip a quarter without anyone warning the buyer. The second issue is firmware, not hardware. Vendors promise the full certified software stack and then ship a bare AOSP image, and the failure only surfaces at the warehouse when the unit is powered on against the customer's app.

The third item is the certification file. A marking without a dated test report is a placeholder, and placeholder paperwork is what turns a routine Brazil clearance into a three-week hold. The answer AndroidSBC applies is to close the gap at the source. Custom variant assembled on the Longgang line, certified image burned, burn-in record traceable per unit, certification file issued with the lot. The nine WF-C3588 variants span ARM PCs, mini PCs, thin clients, NAS enclosures, media stations, home theatre systems, desktop workstations, and personal cloud devices and each carries three memory configurations, which keeps most Brazil requirements on a standard custom SKU rather than a from-scratch run.

Brazil importers usually raise compliance first. 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 answers it by preparing the ANATEL homologation with INMETRO safety conformity documentation for ANATEL before the lot is packed, issuing it with the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), and routing the lot through Port of Santos on the Santos to Shanghai lane.

Competitive Comparison: WF-C3588-P8 vs Competing RK3588 Boards

Three groups of board compete for the custom arm pc, mini pc and nas 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-P8 sits in the third group.

• vs x86 entry desktops: the WF-C3588-P8 runs office and media workloads at a fraction of the power draw, which is the argument for fleet and education deployments.
• vs consumer ARM sticks: dual SATA bays, NVMe and dual GbE make it a real NAS and desktop board rather than a streaming stick.
• vs single-line mini PC brands: the customization path lets a brand keep one platform across a product family while varying memory, storage and chassis.
• vs assembled import boxes: the seven-year supply commitment and the per-lot file give a PC brand a lifecycle story instead of a spot buy.

Global Custom ARM PC and NAS Board Market Trends

The Custom ARM PC and NAS Board market is the frame that decides how Brazil importers time their custom arm pc, mini pc and nas 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:

• Fleet desktop programme: an enterprise replaces ageing towers with fanless ARM PCs at a third of the power draw.
• Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-C3588-P8 board carries that headroom without a board change.
• Home NAS enclosure: a storage brand ships a dual-bay NAS with the NPU running photo search locally.

Channel research on the Custom ARM PC and NAS Board segment keeps landing on the same point: the constraint is allocation, and allocation is held by factories rather than traders.

The common thread for Brazil is that single orders are giving way to blanket agreements released monthly, which is what a twelve-month custom board programme needs in order to avoid a gap in the middle of the year.

"Rail cabinets have no air conditioning and no patience. AndroidSBC routed the CAN and multi-serial lines we asked for, ported the Yocto BSP to our carrier, and the wide-temperature variants have now held through two summers."

- James Whitfield, Programme Manager

Field Report: burn-in room at the Wanlin Longgang plant running a 72-hour continuous loop on 10,510 units of the WF-C3588-P8 board, with rack-wide output monitored by an automatic pattern checker

Reporter Chen Gang, on the ground in Sao Paulo, Brazil. The burn-in room runs pattern generators that alternate between HDR10 and HLG material. Each WF-C3588-P8 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-P8 units hold the burn-in with a yield above 99.18 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-P8 Application Scenarios

The WF-C3588 line fits nine custom motherboard lanes, with the WF-C3588-P8 (Custom ARM PC, Mini PC and NAS Board) as the lead SKU for Sao Paulo and Brazil programmes:

• Fleet desktop programme: an enterprise replaces ageing towers with fanless ARM PCs at a third of the power draw.
• Thin client estate: a bank standardises on one board class across branches with a locked Ubuntu image.
• Home NAS enclosure: a storage brand ships a dual-bay NAS with the NPU running photo search locally.
• Media station build: a CE brand pairs the board with an 8K panel and Widevine-level DRM for a premium player.
• Education desktop: a district deploys locked-down student desktops with MDM enrolment out of the box.
• Personal cloud device: a privacy-focused brand runs sync and backup locally with no cloud dependency.
• Trading desktop: a finance team runs four screens from one board with the desktop image tuned for stability.
• Developer workstation: an engineering shop issues Ubuntu workstations with the NPU for local model testing.

Partnership Models for Sao Paulo Buyers

AndroidSBC runs three engagement tiers for Brazil importers and brand owners sourcing a custom arm pc, mini pc and nas 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-P8 normally lands on the 16GB + 256GB (WF-C3588-P8-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: The customization scope runs across five layers: hardware (PCB, PCBA, I/O, memory, storage), thermal (fanless passive, vented, wide-temperature, conformal coating), software (custom ROM, custom Linux, pre-installed apps, OTA), branding (logo, packaging, boot animation, SKU labels), and compliance (the certification file assembled for the exact configuration you ship). Most Brazil partners change two or three layers on a standard variant rather than commissioning a full custom run.

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

Answer: Custom ROM, custom BSP and custom SDK work are all part of the ODM tier. AndroidSBC builds the Android image (12, 13, 14 or 15, GMS or AOSP), ports the Linux BSP to your carrier revision, and releases the SDK modules your team needs under NDA. The engineering desk carries the port itself, so a Brazil integrator is not left debugging an unmodified vendor BSP against a carrier it was never designed for.

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: Yes. AndroidSBC ships DDP to Amazon FBA warehouses in the US, EU and Japan, and to nominated 3PL consolidation points in Hong Kong, Singapore, Rotterdam, Los Angeles and Shenzhen. Carton labelling and pallet configuration follow FBA inbound requirements, the export declaration names the Wanlin Longgang source factory as the place of origin, and each pallet carries a per-unit barcode that traces back to the burn-in record for downstream RMAs.

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-P8 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.
