Industrial Touch All-In-One Board, WF-RK3568, AndroidSBC, Sofia

TL;DR: Industrial Touch All-In-One Board

SHENZHEN, China, September 10, 2026 - Wanlin Manufacturing Group pushed lot 363 of the WF-RK3568 board out of the Longgang plant this week, 10,510 units for Sofia, Bulgaria, with the export declaration naming Longgang as the place of origin.

AndroidSBC regulatory bulletin on CE, FCC, UKCA and RoHS coverage for the WF-Series serving Sofia, Bulgaria. AndroidSBC is releasing the full WF-Series line for Sofia and Bulgaria: Allwinner A133, H618, and T527 boards on the Allwinner side, and Rockchip RK3588, RK3568, RK3566, and RK3288 boards on the Rockchip side, plus the WF-A133S and WF-RK3588S SOM modules. The family ships from the Wanlin Longgang facility with OEM branding, ODM carrier work, and per-lot CE, FCC, UKCA, and RoHS documentation handled in-house.

About AndroidSBC and the Rockchip RK3568 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 boards on Allwinner and Rockchip silicon for overseas OEM customers for over ten years. The WF-Series line-up is deliberately wide: the Allwinner A133 covers cost-sensitive commercial display and advertising work, the H618 covers OTT and Android TV, the T527 covers industrial control and edge inference, and the Rockchip RK3588, RK3568, RK3566, and RK3288 boards cover 8K video wall, industrial edge, machine vision, and POS respectively. Two SOM variants round the range out for customers who bring their own carrier. Buyers in Sofia and Bulgaria can source any of the nine from one factory with one set of export documents.

WF-RK3568 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-RK3568 (Industrial Edge Computing 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 Bulgaria importers sourcing the WF-Series, the 4GB + 32GB (WF-RK3568-A) variant is the typical configuration for the industrial edge computing use case, with a sustained weekly capacity of 5,000 pcs/wk on the Longgang line.

Challenges in Sourcing Industrial Edge Computing Board for Bulgaria Buyers

The industrial edge computing board sourcing question that Sofia distributors keep coming back to is continuity across quarters. The Rockchip RK3568 requires a dedicated wafer slot, and a 10,510-unit order placed against broker inventory often turns into a two-month slip with no warning. Then comes the software layer. A board that boots is not a board that holds a certified stack under a 72-hour loop, and Bulgaria buyers typically find the difference in their own warehouse rather than at the factory.

Documentation closes the list. Buyers in Sofia have learned to request the test reports before releasing the deposit, because a mark printed on a carton carries no weight at the port if the Technical File behind it does not exist. AndroidSBC handles it by doing 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-Series boards cover industrial edge computing, commercial display controller, industrial HMI, IoT gateway, smart display terminal, machine monitoring, access control, and building automation with three memory configurations each, which means a Sofia integrator can usually match a customer requirement without a custom run.

For Bulgaria specifically, the file travels with the goods. In Bulgaria the market is served largely by regional distributors covering the Balkans, so a single Sofia listing often reaches several neighbouring countries. AndroidSBC prepares the CE marking with CRC radio interface notification documentation for CRC, attaches the standard multi-market pack (CE, FCC, UKCA, RoHS, REACH), and consigns the lot to Port of Varna on the Varna to Piraeus relay.

Competitive Comparison: WF-RK3568 vs Competing RK3568 Boards

The boards competing for the same socket in the industrial edge computing board segment fall into three groups: low-cost legacy SoC boards without a certified software stack, mainstream Cortex-A55 boards with certification but a lower decoder ceiling, and 64-bit boards that carry both but stop short on expansion. The WF-RK3568 sits in the third group and adds three things: Rockchip RK3568, a display path that survives a continuous loop, and the per-lot certified image burn at Longgang.

• vs RK3288 Cortex-A17 boards: the RK3568 Cortex-A55 2.0GHz lifts integer throughput by roughly 2x at lower idle power.
• vs RK3566 boards: the RK3568 adds dual Gigabit Ethernet plus CAN bus for gateway-class builds.
• vs RK3588 boards: the RK3568 keeps a materially lower BOM where 4K@60fps decode is sufficient.
• vs x86 fan-cooled IPC: the RK3568 fanless design removes the only moving part from the enclosure.

Global Industrial Edge Computing and Smart Display Market Trends

Buyers in Sofia are reading the Industrial Edge Computing and Smart Display curve before they commit to a industrial edge computing board programme. Global Growth Insights reports the Android TV Box segment at USD 12.45 billion in 2025 with a 30.49 percent CAGR to USD 178.2 billion by 2035 (Global Growth Insights, 2025-2035), used here as the Android silicon demand baseline rather than as a number for this category. That baseline breaks into three practical demand patterns for the WF-Series in Bulgaria:

• Industrial edge computing: WF-RK3568 runs the edge workload on the 1 TOPS NPU with dual Gigabit uplinks.
• Display and signage refresh cycles: a longer content loop and a higher panel resolution now define the refresh trigger. The WF-RK3568 board carries that headroom without a board change.
• Industrial HMI: WF-RK3568 holds the wide-temperature envelope with the fanless design.

Channel analysts tracking the Industrial Edge Computing and Smart Display category note that allocation discipline, not unit price, has become the deciding factor for buyers who need a twelve-month programme to hold.

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

Partner Success Story: Nordwerk Automation in Sofia, Bulgaria

Nordwerk Automation, an industrial automation integrator serving the Bulgaria market, deployed 7,200 units of the WF-T527 industrial control board for a machine-tool retrofit programme. The rollout covered the industrial edge computing, industrial hmi, and machine monitoring workloads, with AndroidSBC handling the burn-in, the certification scope, and the palletisation at the Wanlin Longgang plant.

• Deployed: 7,200 units of the WF-T527 industrial control board for a machine-tool retrofit programme
• Region: Sofia, Bulgaria
• Models used: WF-A133, WF-H618, WF-T527, WF-RK3588, WF-RK3568, WF-RK3566, WF-RK3288, WF-A133S, WF-RK3588S
• Certifications handled: CE, FCC, UKCA, RoHS, REACH, GMS, Widevine L1, Dolby Audio
• Logistics: FOB Shanghai Yangshan with the Wanlin Group Longgang source factory named on the export declaration, entering Port of Varna via the Varna to Piraeus relay

"The T527 gave us the CAN bus, the dual Ethernet, and the NPU on one board. On the previous platform we ran a separate vision controller next to the HMI, and the retrofit cost reflected it."

Field Report: SMT line No.3 at the Wanlin Longgang plant, with operators loading Rockchip RK3568-based WF-RK3568 boards for the 10,510-unit order bound for Sofia

Reporter Sun Ming, on the ground in Sofia, Bulgaria. Wanlin Longgang SMT line No.3 put the lot through three AOI passes and an X-ray inspection on every BGA package before it reached the burn-in rack. The WF-RK3568 boards then cleared 48 hours of thermal cycling between -20C and 70C with the decoder loaded against a stress stream. Final yield came in at 98.72 percent.

The line supervisor logged a 41-minute changeover between the WF-RK3568 run and the next lot, which is the kind of number that decides whether a mid-quarter top-up order can be absorbed.

The inspection confirmed three things on the spot: the WF-RK3568 units hold the burn-in with a yield above 98.72 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 CRC radio interface notification administered by CRC, cleared for entry at Port of Varna on the Varna to Piraeus relay. 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 Bulgaria importers can hand straight to their customs broker.

WF-RK3568 Application Scenarios

The WF-Series fits nine application lanes, with the WF-RK3568 (Industrial Edge Computing Board) as the lead SKU for Sofia and Bulgaria programmes:

• Industrial edge computing: WF-RK3568 runs the edge workload on the 1 TOPS NPU with dual Gigabit uplinks.
• Commercial display controller: WF-RK3568 drives the 4K@60fps panel pair over HDMI 2.0 and eDP.
• Industrial HMI: WF-RK3568 holds the wide-temperature envelope with the fanless design.
• IoT gateway: WF-RK3568 bridges CAN bus and RS485 field devices onto Ethernet.
• Smart display terminal: WF-RK3568 renders the Android 11 UI on the dual display path.
• Machine monitoring: WF-RK3568 timestamps production data against the onboard RTC.
• Access control: WF-RK3568 runs face recognition on the NPU with the MIPI CSI feed.
• Building automation: WF-RK3568 runs 7x24 with hardware watchdog and scheduled restart.

Partnership Models for Sofia Buyers

The WF-Series is available to Bulgaria 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.

All three tiers ship from Longgang under one documentation pack covering CE, FCC, UKCA, RoHS, and REACH. A Sofia first order on the WF-RK3568 is normally the 4GB + 32GB (WF-RK3568-A) configuration at MOQ 5,000 units per shipment, 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 Bulgaria?

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 Bulgaria-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-RK3568 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.
