Witty Pi 3 Mini supports all Raspberry Pi models that have the 40-pin GPIO header, including A+, B+, 2B, Zero, Zero W, 3B, 3B+, 3A+, and 4 B+.
Raspberry Pi communicates with the RTC chip (DS3231) on Witty Pi 3 Mini via I2C protocol. The DS3231 chip has a fixed I2C address: 0x68. Also Witty Pi 3 Mini has a micro controller (ATtiny841), which also works as an I2C peripheral, and the micro controller's I2C address is 0x69.
Witty Pi 3 Mini uses the same software as Witty Pi 3. You just need to run these two commands in your Raspberry Pi to install the software:
pi@raspberrypi:~ $ wget http://www.uugear.com/repo/WittyPi3/install.sh pi@raspberrypi:~ $ sudo sh install.sh
