Market Demand Analysis: Mexico and Latin America
According to Grand View Research (2025), as locker deployments grow larger, high-density lock control with reliable status feedback has become a core component in the expanding smart locker market. The Latin America region is a particularly dynamic growth zone driven by:
- Large pickup stations needing 48-96 doors under one controller chain
- Door-status feedback reducing maintenance visits to locker sites
- Mixed lock types in one cabinet requiring flexible drivers
- OEMs standardising on RS485 daisy-chain wiring for scalability

Frequently Asked Questions
Q: How many doors can be chained together?
A: Each controller handles 2 to 32 doors, and RS485 daisy-chaining links multiple controllers to one Android motherboard, supporting stations of 96 doors and beyond.
Q: Which lock voltages are supported?
A: The board drives both 12V and 24V electric bolt, electromagnetic and magnetic locks, selected per channel group to match the locker hardware.
Q: Does the board report if a door is left open?
A: Yes. Door magnetic sensors report per-channel status, so the system flags forced or left-open doors and logs the event for maintenance.
Q: What about emergency opening?
A: An emergency unlock interface supports both fail-safe (opens on power loss) and fail-secure (stays locked) configurations per project safety requirements.
Q: Is integration documentation available?
