From the project

Doorbot is an RFID access control platform, primarily intended for exterior doors in a makerspace environment. Based on Raspberry Pi 3b+, PoE hat, and a custom interface hat.

- pihat - Access control hat that sandwiches between a Raspberry Pi 3b+ and a Raspberry Pi PoE hat. It provides isolated Wiegand RFID reader translation as well as isolated PWM solenoid control. - i2clcd - Presently incomplete project for an I2C add-on display for the Doorbot Pi hat.
