BeagleBone Black Door Cape

This is a BeagleBone Black Cape designed for electronically locking or unlocking a single door. It can control either a 12V door strike or a 12V door magnet.

You can order this PCB from oshpark here: https://oshpark.com/shared_projects/fA7vdbq6

The cape has the following features:

  • Dual relays to ensure door is closed if a relay fails
  • opto-isolated GPIO inputs for detecting door status and/or relay failure
  • Jumpers for configuring door strike or door magnet (NO/NC)
  • on-board voltage regulator so BBB can be powered via 12V
  • connectors for two external software controlled 12V lamps
  • LED indicators for 12V, 5V, relay engagement, and external lamps
  • 24C256 EEPROM w/ address configurable via jumpers
  • headers for an RPi/Arduino-compatible realtime clock module
