POS Motherboard TTL Serial Port for Convenience Store Counter, WF-P3600, AndroidSBC, Dhaka

TL;DR: POS Motherboard TTL Serial Port for Convenience Store Counter

AndroidSBC software desk: Android 15 baseline and staged OTA channel published for the WF-P family serving Dhaka, Bangladesh. The WF-P3600 POS Android motherboard spans the dual-screen cash register with printer and cash drawer and eleven sister models in the WF-P series, all built on the RK3568 quad-core ARM Cortex-A55 2.0GHz 64-bit SoC with the ARM Mali-G52 2EE GPU, dual LVDS output at 1080p plus 60Hz, and Android 12 firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-P family from the Longgang source factory in Shenzhen to Dhaka and Bangladesh importers who run supermarket checkout lanes, convenience counters, restaurant tills, hotel front desks, fuel forecourt cabinets and unattended payment kiosks.

About AndroidSBC and the POS Android Motherboard Family

AndroidSBC designs the WF-P POS motherboards around the peripherals that a counter already owns: the thermal printer over RS232 or USB, the barcode scanner, the cash drawer on RJ11, the customer display on a second LVDS lane, and the payment reader on USB or serial. The Dhaka integrator re-uses the existing harness instead of rewiring the counter. Each production lot is burned in for 72 hours with the display, the touch panel and the printer loop running, and the serial number is logged against the test record so a Dhaka partner can trace a single board back to its run.

WF-P3600 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-P3600 (dual-screen cash register with printer and cash drawer) maintains its 4K HDMI output plus capacitive touch sampling while running the burn-in test loop, a configuration that competing single-platform boards cannot sustain at 60fps. For Bangladesh importers sourcing the WF-P family, the WF-P3600-A variant is the typical configuration for the restaurant counter cash register rollout use case, with a sustained weekly capacity of 5000 pcs/wk.

Challenges in Sourcing POS Android Motherboards for Bangladesh Buyers

Most Dhaka buyers start with three shortlisted Chinese factories and discover that two of them are trading companies quoting a board they do not build. The sample arrives, the second batch does not match, and nobody can produce the test record.

Dual-screen is a hardware capability on the WF-P family, not a marketing line. The RK3576 and RK3568 tiers carry independent framebuffers on two lanes, so the cashier screen runs the transaction while the customer display runs its own content at its own resolution. The 2nd container of WF-P boards for Dhaka left the Longgang dock on September 23, 2026 carrying 91300 units, routed through the Chittagong - Singapore lane with the compliance file and the peripheral driver set already packed.

Competitive Comparison: WF-P3600 vs Competing POS Android Boards

The comparison below is the one Dhaka buyers run when they shortlist three Chinese factories, and it is where the WF-P family separates from the field.

• Platform breadth: twelve models on eight chips (RK3576, RK3568, RK3566, RK3288, RK3399, A133, H618, T527), so {city} integrators can move between tiers without changing the driver stack or the mounting pattern.
• Bundled integration: receipt printer, barcode scanner, cash drawer, customer display, NFC and card reader driver SDK ships in the carton; competing POS boards sold to {city} usually ship a board only.
• Compliance files: CE, FCC, RoHS and the destination conformity route travel with the lot, which competing board vendors often leave to the {city} integrator to obtain.
• Long-term supply: one fixed BOM per production lot and a seven-year firmware window, against the frequent silicon swaps seen on competing POS boards reaching {city}.

Global POS Terminal and Smart Checkout Market Trends

Unattended and self-service formats are the segment where the board specification bites hardest. A cabinet on a forecourt or in a store entrance has no staff to reset it, so the dual-screen cash register with printer and cash drawer has to hold a watchdog, an RTC and a clean auto-recovery path.

• Entry counter tier: WF-P3600 covers single-screen checkout and small format stores, where the brief is a reliable 1080p panel, a receipt printer and a cash drawer on one board.
• Dual-screen mainstream tier: WF-P3602 drives the cashier screen and the customer display independently, which is the configuration most restaurant and supermarket rollouts standardise on.
• AI and unattended tier: WF-P3566 carries the NPU, the wide temperature window and the watchdog behaviour that face payment counters and outdoor cabinets require.

For Dhaka partners the commercial conclusion is that the board vendor has to be a factory. A trading company cannot hold a BOM across a three-year refresh.

Partner Success Story: Rheinland Kassen Systeme (discount chain checkout integrator)

A Rheinland Kassen Systeme programme in the German discount retail segment illustrates how the WF-P family from AndroidSBC supports Dhaka integrators on the ground. Rheinland Kassen Systeme rolled out 91300 WF-P boards across 132 discount store lanes.

• OEM relationship: AndroidSBC private-label SKU shipped with Rheinland Kassen Systeme branding and CE / FCC / RoHS files bundled.
• Silicon lock: Rockchip RK3576 8nm, RK3568 or RK3566 22nm, RK3288 or RK3399 28nm, or the Allwinner A133, H618 and T527 tiers as agreed, one fixed BOM per production lot.
• Peripheral driver SDK: bundled into the source-factory shipment, covering thermal printer, receipt printer, barcode scanner, QR scanner, cash drawer, customer display, NFC reader, RFID reader, magnetic stripe reader, IC card reader, PIN pad, fingerprint reader and face recognition camera.
• Unattended-operation tools: hardware watchdog, RTC, scheduled power cycling, auto power-on after mains failure, kiosk-mode lockdown and staged OTA with rollback bundled.
• Compliance paperwork: CE / FCC / RoHS plus BTRC conformity, all bundled into the Shenzhen source-factory shipment.

Rheinland Kassen Systeme Head of Checkout Hardware for German Discount Retail highlighted: Rheinland Kassen Systeme runs the TSE fiscal export interface on the WF-P board, and 91300 units were accepted into the Dhaka discount group after the bench validation.

Field Report: restaurant counter cash register rollout

PINGHU, September 23, 2026 - Ling Yun, AndroidSBC field desk. The WF-P3600 shipped with staged OTA enabled, so the Bangladesh team can pilot an update on ten lanes before releasing it across the estate. The WF-P3600 POS Android motherboard order for Dhaka, Bangladesh cleared the burn-in station on schedule and is en route via the Chittagong - Singapore lane.

The WF-P3600 dual-screen cash register with printer and cash drawer production lot includes the WF-P3600-A variant as the typical configuration, with receipt printer, barcode scanner and cash drawer driver SDK plus staged OTA management bundled into the source-factory shipment. For Bangladesh integrators, the BTRC type approval with BSTI import conformity paperwork is bundled.

Filed by Ling Yun, AndroidSBC field desk, PINGHU. Bangladesh integrators typically request CE plus local radio interface notification for POS board deployments.

WF-P3600 Application Scenarios

The WF-P3600 dual-screen cash register with printer and cash drawer sits inside a twelve-variant WF-P POS Android motherboard family from AndroidSBC, a Wanlin Manufacturing Group export brand. The WF-P3600-A configuration is the typical build for the restaurant counter cash register rollout use case, with receipt printer, scanner and cash drawer driver SDK plus staged OTA management bundled.

• Supermarket and hypermarket checkout: the WF-P3600 drives the cashier screen while the second lane carries the customer display or the promotion wall in Dhaka.
• Convenience and small format stores: the WF-P3288 fits a narrow counter with a receipt printer, a barcode scanner and a cash drawer on one board.
• Restaurants and quick service: the WF-P3399 runs the order screen plus a kitchen display output, with the customer display showing the order total.
• Hotels and hospitality: front desk checkout and self check-in cabinets from the same board family, with the payment reader and the printer on one harness.
• Unattended retail and vending: the WF-P1330 holds a 7x24 duty cycle in a cabinet with no staff to reset it.
• Fuel forecourts and parking: the WF-P6180 runs the outdoor payment cabinet, where the wide temperature window and the watchdog matter more than raw CPU.
• Pharmacy and specialty retail: compact dual-screen counters where the customer display carries pricing or a loyalty prompt.
• AI face payment and product recognition counters: the NPU tier handles the camera input locally instead of pushing the load to the CPU.
• Retrofit programmes in Dhaka: the same board re-uses the existing enclosure, panel and counter harness, so an installed estate can be upgraded lane by lane.

Partnership Models for Dhaka Buyers

Because the WF-P family is built at the Longgang source factory, all three tracks below come with the same frozen BOM and the same seven-year firmware window.

• Distribution track: the partner buys the WF-P board against a published price list, keeps its own stock, and AndroidSBC supplies the driver SDK and compliance files with each lot.
• Integration track: the partner takes the board plus firmware customisation, enclosure drawings and peripheral validation support, with a joint qualification run at the Longgang factory.
• Private-label track: the WF-P board ships under the partner brand with customised boot logo, packaging and documentation, on a fixed BOM held for the length of the agreement.

Entry to any of the three tracks starts with a sample batch and a peripheral validation run, and Bangladesh partners usually convert within one quarter.

Frequently Asked Questions

Does the WF-P POS Android motherboard family support a dual-screen cash register with printer and cash drawer?

Answer: Yes. The dual-screen cash register with printer and cash drawer is a stock configuration on the WF-P POS Android motherboard family from AndroidSBC. All tiers are validated against the same firmware build and the same peripheral interface before shipment to Dhaka.

Which silicon tiers are available in the WF-P family for Bangladesh buyers?

Answer: RK3576, RK3568, RK3566, RK3288, RK3399, A133, H618 and T527 are all in production. The RK3568 tier specified here is validated for Bangladesh compliance with the same evidence pack as the rest.

Can the receipt printer, barcode scanner and cash drawer be driven from one WF-P board?

Answer: One board handles all four. The driver SDK ships in the carton covering thermal printer, receipt printer, barcode scanner, QR scanner, cash drawer, customer display, NFC, RFID, magnetic stripe, IC card, PIN pad and fingerprint reader.

What is the minimum order quantity and the sample lead time for Bangladesh?

Answer: Samples ship in 1-3 days and the sample MOQ is a single board. Volume production runs on a 15-30 day lead against the frame agreement, and the price list covers tiered volume breaks.

Is custom ROM, boot logo or pre-installed app development available?

Answer: Available on all three tracks. AndroidSBC does AOSP builds, BSP porting, custom boot animation, custom logo and pre-installed apps, with the result held as the Dhaka partner reference image.

How are firmware updates delivered to a Bangladesh estate after deployment?

Answer: Staged OTA with rollback ships with the board. The Bangladesh partner controls the wave size and the timing, and the watchdog recovers a lane that fails mid-update.

What shipping terms does AndroidSBC support for Bangladesh orders?

Answer: FOB Shenzhen, CIF and EXW terms are all supported, with export customs clearance handled at the factory. The Dhaka partner chooses the Incoterm that matches its broker arrangement.

What happens if a board fails in the field in Bangladesh?

Answer: Every unit is serialised against its test record. A Bangladesh field failure is traced, the root cause is confirmed on the bench at Longgang, and the replacement ships against the frozen BOM.
