Case Study: Denmark Smart Locker OEM Manufacturer Sourcing Success
Michael Thompson, a Smart Locker OEM Manufacturer based in Denmark, had spent months sourcing 32-channel rs485 lock control board products for the Nordic Europe market. Rising e-commerce volumes, last-mile delivery pressure and unattended-service demand make a reliable control board source essential for any locker partner serving Nordic Europe.
After a 3-month factory search, Michael Thompson selected AndroidSBC (Wanlin Group) as their preferred manufacturing partner. The decision came down to three things:
- Factory-direct quality backed by in-house SMT assembly and functional testing of every board, above the other factories tested
- Complete export documentation (CE / FCC / RoHS / GMS optional) so shipments clear customs without delays
- OEM and ODM customization delivered within 3 weeks

Market Demand Analysis: Denmark and Nordic Europe
According to Grand View Research (2025), as locker banks grow to 60-120 doors, high-density 32-channel lock controllers become standard, riding the same growth as the US$2.4 billion smart locker market. The Nordic Europe region is a particularly dynamic growth zone driven by:
- Operators upsizing cabinets to cut per-door site and maintenance costs
- Daisy-chain RS485 wiring reducing cable runs across large locker banks
- Door status feedback enabling remote monitoring of stuck or forced doors
- Modbus compatibility simplifying integration with existing locker controllers

Frequently Asked Questions
Q: How many doors can one system control?
A: Each board handles 32 channels and boards cascade over RS485, so a single Android motherboard manages 256+ doors with 8+ controllers.
Q: Does it work with 12V and 24V locks?
A: Yes. Jumper or firmware selection supports both 12V and 24V electric locks, magnetic locks and bolt locks.
Q: What is door status feedback for?
A: Each channel reports open/closed state, so the CMS flags forced entries, stuck doors and unresolved pickups in real time - critical for unattended sites.
Q: Can it replace a failed board in an existing locker?
A: Usually yes. Modbus RTU and standard wiring make it a drop-in retrofit for many legacy cabinets; send us the old board's protocol sheet for confirmation.
Q: What protection does the board include?
A: Overcurrent, short-circuit and reverse-polarity protection per channel group, plus optical isolation on the RS485 bus.
