TL;DR: Main Screen + Customer Screen Board
AndroidSBC manufacturer capacity statement from the WF-S production base serving Seville, Spain. The WF-S3504 self-service checkout Android motherboard spans the industrial fanless self-checkout SBC and eight sister models (WF-S3500 through WF-A1303), all built on the RK3568 quad-core ARM Cortex-A55 2.0GHz 64-bit SoC with the Mali-G52 2EE GPU and 1 TOPS NPU, HDMI 4K + dual LVDS, and Android 13 / Linux firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-S family from the Longgang source factory in Shenzhen to Seville and Spain importers who run self-checkout, POS terminal, kiosk, dual-screen cashier, smart retail, and unmanned-store programs.

About AndroidSBC and the Self-Service Checkout Android Motherboard Family
For global retail and hospitality integrators, AndroidSBC supplies the WF-S self-service checkout Android motherboard family as a turnkey source-factory program. The Wanlin Longgang facility assembles each WF-S variant on automated SMT lines with 100 percent AOI inspection, then burns in the Android 12 or Android 13 firmware with the payment, scanner, printer, and weighing-scale drivers pre-loaded. For Spain in particular, the WF-S platform addresses the self-checkout and POS terminal distribution channel where local supermarket chain procurement teams, hospitality refresh integrators, F&B kiosk vendors, and unattended-retail program operators looking for the global self-checkout / POS / kiosk supply base all converge on the same architecture.

Challenges in Sourcing Self-Service Checkout Android Motherboards for Spain Buyers
Spain importers evaluating Chinese self-service checkout Android motherboard factories usually compare three things: pricing per tier, firmware support for payment peripherals, and time-to-first-sample. The WF-S self-service checkout Android motherboard family from AndroidSBC, a Wanlin Manufacturing Group export brand, covers all three with a 1-3 day sample lead, an Android 10 to Android 14 firmware baseline, and bundled payment-peripheral driver SDKs.
For Spain buyers, the CNMC registration plus CE marking with CNMC radio interface notification is the typical compliance anchor for self-checkout Android motherboards with WiFi 6 or 4G LTE modules. AndroidSBC, a Wanlin Manufacturing Group brand, ships the WF-S family with the CNMC paperwork bundled so that Seville importers clear Port of Valencia customs in one pass. Wanlin Longgang SMT line released a 147800-unit WF-S self-service checkout Android motherboard lot for Seville, Spain on September 14, 2026, the 3rd lot on the WF-S production line.
Competitive Comparison: WF-S3504 vs Competing Self-Service Checkout Android Boards
Spain procurement teams comparing Chinese self-service checkout Android motherboard factories usually focus on silicon lock, payment-peripheral driver support, OTA content management, and CE / FCC paperwork. The WF-S family from AndroidSBC addresses all four:
- vs single-platform 28nm boards: the WF-S family covers both Rockchip RK3568 8nm premium tier and Allwinner A133 22nm entry tier from one Shenzhen source factory.
- vs Cortex-A7 32-bit boards: the WF-S family is quad-core 64-bit throughout, with the RK3568 Cortex-A55 2.0GHz and the A133 Cortex-A53 1.6GHz both on the ARMv8 instruction set.
- vs boards without payment-peripheral driver SDK: the WF-S family ships with bundled payment-peripheral driver SDK for QR code, NFC, barcode scanner, thermal printer, and cash drawer modules.
- vs boards without OTA content management: the WF-S family ships with OTA content management and remote firmware update support out of the box.
