TL;DR: RK3588 Custom Multi-Screen Board
SHENZHEN, China, September 12, 2026 - The WF-C3588-M2 board line at Wanlin Longgang closed lot 244 this week. 26,460 units are now booked for Philadelphia, United States, shipped FOB with the full certification file attached.
AndroidSBC export paperwork update on the nine-variant WF-C3588 custom board line serving Philadelphia, United States. 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 Philadelphia and United States 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 Philadelphia and United States can source any of the nine custom variants from one factory with one set of export documents.

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-C3588-M2 (Custom Core Board SOM with Carrier Board Design Service) 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 United States importers sourcing the WF-Series, the 16GB + 64GB (WF-C3588-M2-C) variant is the typical configuration for the custom core board and SOM plus carrier programmes use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.
Challenges in Sourcing Custom Core Board SOM with Carrier Board Design Service for United States Buyers
Buyers in Philadelphia who have sourced a custom core board som with carrier board design service 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 26,460-unit order placed against trader stock is the order most likely to slip a quarter without anyone warning the buyer. Software continuity is the second trap. A bare Android image boots fine on the bench, so the problem tends to appear only after the Philadelphia customer has taken delivery and the first OTA push fails against the DRM credentials.
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 United States 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 SMARC 2.2 modules, stamp-hole core boards, LGA core boards, COM Express carriers, medical imaging terminals, robotics compute modules, custom carrier designs, and OEM development kits and each carries three memory configurations, which keeps most United States requirements on a standard custom SKU rather than a from-scratch run.
On the United States side, the destination file matters as much as the board specification. In the United States FCC Part 15 authorisation is required and an FCC ID applies to radio modules, while UL or ETL listing is usually demanded by the retail channel. The export desk prepares the destination-market file covering FCC Part 15 authorisation with an FCC ID for radio modules and a UL or ETL listing, administered by FCC / UL, and releases it with the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH). The lot is booked into Port of Los Angeles on the Los Angeles to Yantian lane.
Competitive Comparison: WF-C3588-M2 vs Competing RK3588 Boards
Competing boards in the custom core board som with carrier board design service category sort into three camps: cheap catalogue boards with no customization, re-badge imports with a sticker but no engineering file, and source-factory custom boards with the BSP, the certification and the test bench in one building. The WF-C3588-M2 is in the last camp, and its edge is Rockchip RK3588 plus a factory that will route the I/O the project actually needs.
- vs standard SOM catalogues: the WF-C3588-M2 either matches SMARC 2.2 exactly or the carrier is redesigned around the project, so the module never forces the product.
- vs two-vendor module plus carrier splits: core board and carrier come from one desk, one schematic review and one test plan, which removes the finger-pointing stage entirely.
- vs closed-module vendors: BSP source, SDK and documentation ship with the project, so a customer engineering team can maintain the carrier after delivery.
- vs re-branded modules: the SI report and the thermal map are Longgang documents, not forwarded PDFs from a third party.
Global Custom SOM and Core Board Market Trends
The Custom SOM and Core Board curve is what United States importers read before committing to a custom core board som with carrier board design service programme. The number they quote is 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, Edge AI Hardware Market Report, 2025-2030), which serves as the closest public proxy for the silicon demand behind custom RK3588 boards. For Philadelphia that resolves into three demand patterns across the WF-C3588 order book:
- Medical imaging terminal: a device maker keeps its regulatory file intact by swapping the core board and reusing the validated carrier.
- Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-C3588-M2 board carries that headroom without a board change.
- Custom SMARC migration: a legacy SMARC installation moves to RK3588 with a pin-compatible carrier revision and keeps the enclosure.
Channel research on the Custom SOM and Core Board segment keeps landing on the same point: the constraint is allocation, and allocation is held by factories rather than traders.
Taken together, the three patterns explain why United States buyers are moving from single orders to twelve-month framework agreements with a monthly lot cadence, especially on custom board programmes that cannot absorb a supply gap.

Field Report: a machine-tool retrofit at a manufacturing plant outside Philadelphia, where 26,460 units of the WF-C3588-M2 board were commissioned onto existing production lines
Reporter Jiang Bo, on the ground in Philadelphia, United States. Commissioning engineers wired the WF-C3588-M2 boards into the existing fieldbus and ran a 96-hour production trial before sign-off. The boards held the cycle time on every line, and the plant's maintenance team kept two spares per line on the shelf rather than a full spare controller.
The line ran the WF-C3588-M2 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-M2 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 FCC Part 15 authorisation with an FCC ID for radio modules and a UL or ETL listing administered by FCC / UL, cleared for entry at Port of Los Angeles on the Los Angeles to Yantian 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 United States importers can hand straight to their customs broker.

WF-C3588-M2 Application Scenarios
The WF-C3588 line fits nine custom motherboard lanes, with the WF-C3588-M2 (Custom Core Board SOM with Carrier Board Design Service) as the lead SKU for Philadelphia and United States programmes:
- Medical imaging terminal: a device maker keeps its regulatory file intact by swapping the core board and reusing the validated carrier.
- Robotics compute module: an AMR maker takes the stamp-hole core board and designs a slim carrier for a new chassis generation.
- Custom SMARC migration: a legacy SMARC installation moves to RK3588 with a pin-compatible carrier revision and keeps the enclosure.
- OEM development kit: a product team gets the reference carrier, the SDK and the BSP source and prototypes before committing to tooling.
- LGA core board programme: a display brand solders the core board directly onto its own mainboard for a locked BOM.
- Machine vision carrier: a vision integrator routes MIPI CSI-2 lanes to four cameras and lets the NPU carry the inspection model.
- Fleet compute module: a telematics supplier builds one carrier for three vehicle programmes and swaps memory options per contract.
- Lab instrumentation: an instrument maker keeps a decade-old enclosure alive by replacing only the core board and the BSP.
Partnership Models for Philadelphia Buyers
AndroidSBC opens the WF-C3588 to United States partners through three structures, and a single agreement can draw on more than one:
- 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.
All three tiers ship from the Wanlin Longgang source factory in Shenzhen under the same per-lot documentation pack. For Philadelphia buyers, a typical first order on the WF-C3588-M2 is the 16GB + 64GB (WF-C3588-M2-C) configuration at MOQ 5,000 units per shipment, with standard-variant samples in 1-3 days and 15-30 days to mass production on custom runs.
Frequently Asked Questions
What exactly can be customised on an RK3588 motherboard from AndroidSBC?
Answer: Practically the layers that decide whether the board fits your product: the PCB layout and outline, the memory and storage fit (4GB to 32GB LPDDR4X/LPDDR5, eMMC to 128GB plus NVMe or SATA), the display interface mix (HDMI 2.1, DP 1.4, LVDS/eDP/MIPI), the I/O bank (CAN, RS232/RS485 multi-serial, relays, digital I/O), the wireless stack, and the enclosure or DIN-rail chassis. On top of that sit the firmware options: custom Android ROM with a locked launcher, custom Linux or Yocto image, pre-installed applications, custom boot animation and OTA updates. A United States buyer can start from a standard WF-C3588 variant and change one layer, or bring a full schematic and have the carrier designed from scratch.
Can AndroidSBC port a custom Android ROM or a custom Linux BSP to our carrier board?
Answer: Yes. Under NDA, AndroidSBC delivers custom Android ROM work with proprietary services and a locked launcher, custom Linux images on Ubuntu, Debian, Yocto or Buildroot, BSP ports for customer carriers, and driver development for project-specific I/O. Source access is released to the partner, and the port is performed at Longgang, which matters because a vendor BSP rarely matches a custom carrier revision on the first try.
Can the 6 TOPS NPU on a custom board run our own AI models?
Answer: The NPU is fully open on the custom line. Bring the model in PyTorch, ONNX, TensorFlow or Caffe and the Longgang desk handles the RKNN quantization, the runtime integration and the validation against your board's thermal and memory profile. Custom AI algorithm integration is a standard line item on the ODM scope, and the resulting model ships embedded in the firmware image burned per lot.
What are the MOQ and lead times for a custom RK3588 motherboard?
Answer: Standard-variant samples ship in 1-3 days from stock, so your engineering team can start integration while the custom scope is being quoted. A custom run follows a 15-30 day mass-production window after schematic and stack-up sign-off. MOQ is 5,000 units per shipment on standard variants; on custom configurations the MOQ is negotiable against volume commitments, and small batch orders are accepted for pilot phases. A twelve-month framework agreement with monthly lot releases brings the per-lot MOQ down further.
What certifications does a custom board need for United States, and who handles them?
Answer: Yes, and the file travels with the goods. The pack covers CE, FCC Part 15, UKCA, RoHS 2.0, REACH and IEC 62368-1 with the EMC and safety reports for your configuration, dated within the prior year. AndroidSBC confirms any United States-specific addition at quotation stage, which is the point where the answer is still useful rather than expensive.
How long will AndroidSBC keep supplying a custom board?
Answer: Seven years minimum supply, patches maintained across the firmware lines, OTA for firmware and NPU model updates. For a United States programme running a custom board in the field, that commitment is written into the agreement at signature, which is what separates a source factory from a catalogue reseller.
Can AndroidSBC ship custom boards to Amazon FBA warehouses or 3PL consolidation points?
Answer: Yes, including DDP into Amazon FBA in the US, EU and Japan, plus 3PL consolidation points in Hong Kong, Singapore, Rotterdam, Los Angeles and Shenzhen. Cartons are labelled to FBA inbound spec and the declaration names Longgang as the origin. Partners who consolidate in Hong Kong usually take FOB Yantian and handle the last leg themselves.
How does AndroidSBC handle RMA or DOA replacements on custom boards?
Answer: AndroidSBC targets a 0.3 percent DOA rate across the WF-C3588 line, measured over the prior twelve months. On RMA, the partner returns the faulty WF-C3588-M2 unit to Longgang with its burn-in barcode, and a replacement ships within ten business days. Because the burn-in record and the configuration file are attached per unit, the failure analysis normally comes back with a root cause rather than a credit note, which matters when a custom configuration is holding up a production line.
