Train Station Query Voice Board, WF-K3288, AndroidSBC, Dhaka

TL;DR: Train Station Query Voice Board

AndroidSBC field desk: query rollout map updated across hospitals, bank branches, government halls, malls and airports serving Dhaka, Bangladesh. The WF-K3288 self-service query terminal Android motherboard spans the legacy query terminal refresh with hall display and eleven sister models in the WF-K series, all built on the RK3288 quad-core ARM Cortex-A17 1.8GHz SoC with the ARM Mali-T764 GPU, 1080p HDMI plus LVDS, and Android 10 firmware support. AndroidSBC, the export arm of Wanlin Manufacturing Group, ships the WF-K family from the Longgang source factory in Shenzhen to Dhaka and Bangladesh importers who run hospital information points, bank branch lobbies, government service halls, mall directory stations, airport concourses and outdoor query cabinets.

About AndroidSBC and the Self-Service Query Terminal Android Motherboard Family

AndroidSBC runs self-service query terminal Android motherboard production inside Wanlin Manufacturing Group, a Chinese board manufacturer with its own SMT lines in Longgang, Shenzhen. For Bangladesh importers the practical point is that the WF-K series keeps one twelve-model catalogue, one driver SDK and one compliance file set across every tier a Dhaka project might need. The plant holds a standing allocation of LPDDR4X and eMMC for the WF-K line, which is how Dhaka projects keep their lead times stable across quarters.

WF-K3288 Technical Specifications

All parameters in the table above are measured at 25C ambient. The AndroidSBC WF-K3288 (legacy query terminal refresh with hall display) 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-K family, the WF-K3288-A variant is the typical configuration for the installed-base query terminal refresh use case, with a sustained weekly capacity of 5000 pcs/wk.

Challenges in Sourcing Self-Service Query Terminal Android Motherboards for Bangladesh Buyers

Many Bangladesh integrators under-estimate the peripheral side of a query terminal. The board is one line item, but the printer, scanner, card reader and touch drivers decide whether Dhaka can actually ship a working station.

The third constraint is the evidence pack. Dhaka integrators bidding on public work in Bangladesh are routinely asked to show the BTRC trail behind BTRC type approval with BSTI import conformity, which is where a factory-direct supplier earns its place. AndroidSBC deals with it by treating the Dhaka requirement as one lot of 154800 units on one BOM, quoted on September 22, 2026 and shipped over the Chittagong - Singapore lane.

Competitive Comparison: WF-K3288 vs Competing Self-Service Query Terminal Android Boards

Competing query boards in Bangladesh often win on headline price until the Dhaka integrator prices in the missing driver SDK and compliance files.

• Platform breadth: twelve models on eight chips (RK3588, RK3568, RK3566, RK3288, RK3399, A133, H618, T527), so {city} integrators can move between tiers without changing driver stack or mounting pattern.
• Bundled integration: touch, printer, scanner, card reader, camera and voice driver SDK ships in the carton; competing query 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 query boards reaching {city}.

Global Self-Service Query Terminal / Information Kiosk Market Trends

The query terminal category is expanding faster than the general kiosk market because it replaces a staffed desk rather than supplementing one. In Bangladesh that shows up as bundled tenders covering the legacy query terminal refresh with hall display together with hall displays and information screens, and Dhaka operators are following the same pattern.

• Volume shift to board-level sourcing: more integrators now buy the motherboard rather than the finished kiosk, which is why the WF-K3288 and WF-K3399 tiers ship in board form with the enclosure left to the local partner.
• Dual-screen becomes the default: hall display plus touch query on one board is replacing two separate devices, and the WF-K3399 and WF-K1330 configurations address that pattern directly.
• Longer service life expectations: operators now plan five to seven years per query terminal, which favours a fixed BOM such as the WF-K1330 over boards that re-spin silicon between lots.

For Dhaka the practical reading is that query terminal demand is not a spike but a standing requirement, and Bangladesh operators are buying on repeatability rather than on a one-off price.

Partner Success Story: Rheinland Auskunft Systeme (municipal information system house)

The Rheinland Auskunft Systeme case in the Germany public sector segment is a working example of how the WF-K family from AndroidSBC supports Dhaka integrators. Rheinland Auskunft Systeme supplied 154800 query boards with site-specific number formats.

• OEM relationship: AndroidSBC private-label SKU shipped with Rheinland Auskunft Systeme branding and CE / FCC / RoHS files bundled.
• Silicon lock: Rockchip RK3588 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 capacitive touch, thermal printer, receipt printer, document scanner, A4 printer, barcode scanner, QR code, NFC, RFID, card reader, ID reader, face recognition, voice module, speaker amplifier and microphone.
• 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.

As Rheinland Auskunft Systeme Leiter Technik for Germany Public Sector put it: Rheinland Auskunft Systeme needed the display board to accept municipal number formats, and the WF-K board handled it across 154800 units installed in Dhaka without a custom firmware fork.

Field Report: installed-base query terminal refresh at a social security service hall

LONGGANG, Shenzhen, September 22, 2026 - Lai Feng, AndroidSBC field desk. Burn-in for the WF-K3288 batch ran the touch, printer and card reader loops simultaneously, which is the combination Bangladesh integrators actually meet in the field. The WF-K3288 self-service query terminal Android motherboard order for Dhaka, Bangladesh cleared the burn-in station on schedule and is en route via the Chittagong - Singapore lane.

The WF-K3288 legacy query terminal refresh with hall display production lot includes the WF-K3288-A variant as the typical configuration, with touch panel, thermal printer and document scanner 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 Lai Feng, AndroidSBC field desk, LONGGANG, Shenzhen. Bangladesh integrators typically request CE plus local radio interface notification for self-service query terminal board deployments.

WF-K3288 Application Scenarios

The WF-K3288 legacy query terminal refresh with hall display sits inside a twelve-variant WF-K self-service query terminal Android motherboard family from AndroidSBC, a Wanlin Manufacturing Group export brand. The WF-K3288-A configuration is the typical build for the installed-base query terminal refresh use case, with touch panel and identity peripheral driver SDK plus staged OTA management bundled.

• Hospital and clinic information points: the WF-K3288 drives a touch query station at the entrance while the hall display shows the same information set to waiting visitors in Dhaka.
• Bank and financial branch lobbies: touch query plus counter display from one board, with card reader and ID reader integrated for account and product lookups.
• Government service halls: the WF-K1331 runs tax, social security and real estate information lookup, with printing available on the same board.
• Shopping mall directories: the WF-K6180 serves mall directory and wayfinding lookup, with the advertising screen running an independent content loop.
• Airport and train station concourses: high-brightness information query where the WF-K5270 has to stay readable under strong ambient light.
• Retail and pharmacy price or product lookup: compact stations where the WF-K8800 fits a narrow counter without structural work.
• Outdoor and unheated information cabinets: the industrial tier holds the wide temperature window and 7x24 duty cycle for street-level query points.
• Multi-language public information points: on-screen lookup in more than one language from a single board, with voice assistance where the venue requires it.
• Retrofit programmes in Dhaka: the same board re-uses the existing enclosure, panel and mounting pattern so an installed estate can be upgraded board by board.

Partnership Models for Dhaka Buyers

AndroidSBC works with Dhaka integrators on three commercial tracks rather than one, because Bangladesh projects differ in how much of the stack the local partner wants to own.

• Distribution track: the partner buys the WF-K 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-K board ships under the partner brand with customised boot logo, packaging and documentation, on a fixed BOM held for the length of the agreement.

For Bangladesh buyers the sequencing advice is simple: prove the board on one pilot site in Dhaka, then choose the track that matches the volume the pilot generates.

Frequently Asked Questions

Does the WF-K self-service query terminal Android motherboard family support a legacy query terminal refresh with hall display?

Answer: Yes. AndroidSBC ships the legacy query terminal refresh with hall display as a standard configuration, and the touch, printer and card reader drivers for it are integrated into the factory image rather than added by the Dhaka integrator on site.

What is the real difference between the RK3288 tier and the other silicon tiers in the WF-K family?

Answer: The RK3288 tier differs in compute headroom, display capability and NPU availability rather than in board-level interfaces. All WF-K models share the same mounting pattern, the same peripheral pinout and the same firmware baseline, so a Bangladesh project can move between tiers without re-designing the enclosure.

Can AndroidSBC handle CE / FCC / UKCA / RoHS / REACH paperwork for Bangladesh?

Answer: Yes. AndroidSBC prepares the conformity file set for Bangladesh as part of the order, covering CE, FCC, RoHS and REACH as applicable, plus the destination-specific route. The documents travel with the Dhaka shipment rather than following it.

What are the MOQ and lead time for a first order of the WF-K self-service query terminal family?

Answer: For Dhaka the entry MOQ is low enough to validate one site before committing to an estate, with 1-3 day samples and a 15-30 day first bulk lead time for Bangladesh.

Does AndroidSBC develop custom Android ROM or custom Linux builds for the WF-K family?

Answer: Yes, and the custom build is maintained as a branch rather than a one-off, so Dhaka partners receive updates against their own image for as long as the Bangladesh programme runs.

How are software updates and long-term support handled on the WF-K family?

Answer: The WF-K family runs a staged OTA channel with rollback. Updates are released against the shared firmware baseline, and Dhaka integrators can hold a Bangladesh estate on a known revision while a new build is validated.

Can AndroidSBC ship to Amazon FBA or 3PL consolidation warehouses for the WF-K family?

Answer: Yes. Boards for Dhaka can be routed straight into Amazon FBA or a third-party 3PL in Bangladesh, with the labelling and packing specification confirmed before the lot is packed.

How are RMA and DOA replacements handled on the WF-K self-service query terminal family?

Answer: DOA and RMA cases are managed by lot, with replacement units supplied from a matching build so a Dhaka partner does not end up with mixed firmware across a Bangladesh estate.
