Wide Temperature -40C to 85C Board, WF-RK3588S, AndroidSBC, Warsaw
TL;DR: Wide Temperature -40C to 85C Board
SHENZHEN, China, September 10, 2026 - Wanlin Longgang released a 19,065-unit WF-RK3588S lot for Warsaw, Poland this week, the 405th run booked against the Rockchip RK3588 allocation.
AndroidSBC procurement notice on the WF-Series custom board supply position serving Warsaw, Poland. The WF-Series is a nine-board line rather than a single part number, and the shape is deliberate. Allwinner A133, H618, and T527 cover cost-sensitive display, OTT and Android TV, and industrial edge inference; Rockchip RK3588, RK3568, RK3566, and RK3288 cover 8K video wall, industrial edge, machine vision, and POS; WF-A133S and WF-RK3588S are SOM modules for carrier-board projects. A Warsaw buyer can hold one supplier file, one documentation format, and one MOQ structure across every tier it sells.

About AndroidSBC and the Rockchip RK3588 Board Family
AndroidSBC is the export brand of Wanlin Manufacturing Group, a Shenzhen source-factory group that has spent more than a decade building OEM/ODM boards on Allwinner, Rockchip, and Amlogic silicon. The line this release covers is the WF-Series: nine boards that between them span the Allwinner A133, Allwinner H618, Allwinner T527, Rockchip RK3588, Rockchip RK3568, Rockchip RK3566, and Rockchip RK3288 platforms, plus two board-to-board SOM options. Wanlin's Longgang plant in Shenzhen builds the WF-Series for OTT TV box, Android TV, commercial display, industrial control, edge AI, POS, kiosk, and IoT gateway programmes. For Poland, the practical value of the range is that a single supplier relationship covers several silicon platforms, so a distributor assembling a Warsaw catalogue does not have to open a new vendor file every time a customer asks for a different performance tier.

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-RK3588S (SOM Module and SMARC Carrier 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 Poland importers sourcing the WF-Series, the 8GB + 64GB, SMARC 2.2 (WF-RK3588S-A) variant is the typical configuration for the SMARC module and custom carrier integration use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.
Challenges in Sourcing SOM Module and SMARC Carrier Board for Poland Buyers
What breaks Poland sourcing plans on the som module and smarc carrier board line is not price negotiation, it is the second shipment. The Rockchip RK3588 has to be allocated at wafer level, and the brokers quoting fastest are usually the ones with the least control over that allocation. The software side is the second exposure. A board that boots on the bench is not the same as a board that carries the certified stack a Poland channel will accept, and the difference usually shows up during inbound inspection rather than at the factory gate.
The third issue is documentation. Some factories stamp the CE mark without the Declaration of Conformity and the Technical File behind it, and the container then sits at the port while the importer tries to reconstruct a test report from a supplier who has already been paid. The answer AndroidSBC applies is to move both risks upstream: the certified image is burned at Longgang, the burn-in record is attached per unit, and the Technical File ships with the lot rather than after it. Across the nine WF-Series boards, the coverage runs from SMARC module design, COM Express Type 6 builds, edge AI boxes, video wall controllers, medical imaging terminals, autonomous vehicle compute, and bespoke industrial carriers, so a Poland buyer can generally find a standard configuration instead of paying for a bespoke one.
Compliance for Poland is handled at the factory rather than after arrival. In Poland the market has become the main distribution hub for Central Europe, so a Gdansk or Warsaw listing often serves several neighbouring countries. The Longgang export desk builds the destination-market file for CE marking with UKE radio interface notification administered by UKE and issues it alongside the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), with the shipment booked into Port of Gdansk on the Gdansk to Ningbo lane.
Competitive Comparison: WF-RK3588S vs Competing RK3588 Boards
The comparison set for the som module and smarc carrier board socket splits three ways: legacy SoC boards priced low and uncertified, Cortex-A55 boards that carry certification but cap decode early, and 64-bit boards with both. The WF-RK3588S sits in the third group, differentiated by Rockchip RK3588, by display stability under a continuous load, and by the factory-side certified image burn.
- vs proprietary SOM pin-outs: the SMARC 2.2 standard lets the carrier survive a module generation change without a re-layout.
- vs RK3568 SMARC modules: the RK3588 module adds 8K@60fps decode, PCIe 3.0 x4, and 6 TOPS NPU on the same 314-pin edge.
- vs x86 COM Express modules: the RK3588 module runs Android natively, which removes the OS licensing line from the BOM.
- vs module-only vendors: AndroidSBC ships the carrier reference design plus the signal integrity report with the module.
Global SMARC and COM Express Module Engineering Market Trends
The SMARC and COM Express Module Engineering market is the frame that decides how Poland importers time their som module and smarc carrier board orders. The figure most Poland buyers quote when they argue about allocation is the Android TV Box segment, which Global Growth Insights sizes at USD 12.45 billion in 2025 with a 30.49 percent CAGR through 2035 (Global Growth Insights, Android TV Box Market Report, 2025-2035); it is the public proxy for Android-on-silicon demand rather than a forecast for this board category. For Warsaw, three buying patterns are shaping the WF-Series order book:
- SMARC module design: WF-RK3588S seats on the 314-pin MXM edge with the carrier holding the I/O.
- Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-RK3588S board carries that headroom without a board change.
- Edge AI boxes: WF-RK3588S runs 6 TOPS NPU inference on the carrier-side thermal solution.
The read across the SMARC and COM Express Module Engineering channel is that buyers are consolidating suppliers: fewer vendors, wider platform coverage per vendor, and a longer contract behind each order.
In all three cases, Warsaw buyers are converting spot quotes into blanket orders with a monthly lot release, because a programme that has to hold a twelve-month shipping window cannot tolerate a mid-year allocation break.
Partner Success Story: StreamTV Distribution in Warsaw, Poland
StreamTV Distribution, a consumer electronics distributor serving the Poland market, deployed 26,000 units of the WF-H618 OTT board into a retail channel with national shelf programmes. The rollout covered the smarc module design, edge ai boxes, and autonomous vehicle compute workloads, with AndroidSBC handling the burn-in, the certification scope, and the palletisation at the Wanlin Longgang plant.

Field Report: container yard at Yantian, where 19,065 WF-RK3588S boards from the Wanlin export base are being loaded onto containerised pallets with the customs declaration naming the Longgang source factory
Reporter Guo Peng, on the ground in Warsaw, Poland. The yard crew handled the order on flat pallets wrapped in anti-static film, with every carton barcode-traced back to the burn-in record. The customs broker attached a single declaration naming the Wanlin Longgang source factory as the place of origin, and the container was sealed before the afternoon cut-off.
A carton-level audit matched 40 sampled serials against the burn-in database with no mismatch.
The inspection confirmed three things on the spot: the WF-RK3588S units hold the burn-in with a yield above 98.94 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 CE marking with UKE radio interface notification administered by UKE, cleared for entry at Port of Gdansk on the Gdansk to Ningbo lane. Wanlin remains one of the few source factories currently shipping a nine-board Allwinner and Rockchip custom line with a per-lot paper trail that Poland importers can hand straight to their customs broker.

WF-RK3588S Application Scenarios
The WF-Series fits nine application lanes, with the WF-RK3588S (SOM Module and SMARC Carrier Board) as the lead SKU for Warsaw and Poland programmes:
- SMARC module design: WF-RK3588S seats on the 314-pin MXM edge with the carrier holding the I/O.
- COM Express Type 6 builds: WF-RK3588S maps to the Type 6 pin-out for existing x86 carriers.
- Edge AI boxes: WF-RK3588S runs 6 TOPS NPU inference on the carrier-side thermal solution.
- Video wall controllers: WF-RK3588S drives HDMI 2.1 and DP 1.4 out through the carrier.
- Medical imaging terminals: WF-RK3588S pairs PCIe 3.0 x4 with the carrier frame grabber.
- Autonomous vehicle compute: WF-RK3588S holds -40C to 85C on the automotive-grade carrier.
- Bespoke industrial carriers: WF-RK3588S ships the signal integrity report for the customer stack-up.
- Carrier bring-up: WF-RK3588S comes with the BSP port for the carrier revision.
Partnership Models for Warsaw Buyers
For Warsaw importers and brand owners, the WF-RK3588S and the rest of the WF-Series are available under three contract shapes:
- 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 tier a Poland partner picks, the goods leave Longgang with one documentation pack covering CE, FCC, UKCA, RoHS, and REACH. The usual first order on the WF-RK3588S is the 8GB + 64GB, SMARC 2.2 (WF-RK3588S-A) configuration at MOQ 5,000 units, four weeks for samples and six weeks for mass production.
Frequently Asked Questions
Does the WF-Series support certified Android TV or Google Mobile Services?
Answer: It depends on the platform, and AndroidSBC is explicit about the split. The WF-H618 carries the ATV 12 GMS build with Widevine L1 and Dolby Audio pre-burned at the factory. The WF-A133, WF-T527, and the Rockchip boards ship with an AOSP or Linux image by default, and a GMS build can be prepared for ODM partners who need Play Services in the field. Certification scope is agreed per project rather than assumed.
What is the difference between the nine WF-Series models?
Answer: WF-A133 is the Allwinner A133 commercial display and advertising board. WF-H618 is the Allwinner H618 OTT TV box and Android TV board. WF-T527 is the Allwinner T527 octa-core industrial control and edge AI board. WF-RK3588 is the Rockchip RK3588 8K video wall and AI computing board. WF-RK3568 is the Rockchip RK3568 industrial edge board. WF-RK3566 is the Rockchip RK3566 machine vision and HMI board. WF-RK3288 is the Rockchip RK3288 POS and signage board. WF-A133S is an Allwinner A133 SOM module for custom carrier work. WF-RK3588S is a Rockchip RK3588 SMARC 2.2 module for the same purpose.
Can AndroidSBC handle CE, FCC, UKCA, RoHS, and REACH paperwork for Poland?
Answer: Yes, and the file travels with the goods rather than behind them. The pack covers CE, FCC Part 15, UKCA, RoHS 2.0, and REACH with test reports dated within the prior year. AndroidSBC will also advise on any Poland-specific addition during quotation, which is the point at which the answer is still useful.
What are the MOQ and lead time for a first order?
Answer: The entry point is 5,000 units per shipment, four weeks for samples and six weeks for production. A twelve-month framework agreement released monthly will bring the per-lot MOQ down, and AndroidSBC will accept a mixed order that draws several WF-Series boards against a single contract.
Does AndroidSBC support custom Android ROM or custom Linux development?
Answer: Custom ROM and custom Linux work is part of the ODM tier. That covers proprietary Android services, a locked-down launcher, Yocto or Debian or Buildroot images, and BSP ports for custom carriers. Source access is released under NDA, and the Longgang engineering desk carries the port so the partner is not left with an unmodified vendor BSP.
What about software updates and long-term support?
Answer: Wanlin commits to a minimum seven-year supply window across the WF-Series. Security patches are back-ported across the Android and Linux firmware tracks for as long as the board is in production, and AndroidSBC provides OTA update infrastructure for partners who need to push firmware to field-deployed units. For POS and industrial programmes, the support commitment is written into the framework agreement rather than left as an understanding.
Can AndroidSBC ship 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, and Los Angeles. 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?
Answer: The DOA target is 0.3 percent over twelve months. For RMA, partners send the WF-RK3588S unit back to Longgang with the burn-in barcode attached, and replacements go out within ten business days. The per-unit burn-in record means the failure report usually carries a root cause alongside the replacement.
