It's a small electronic board that can add real-time clock and power management to your Raspberry Pi. Witty Pi 3 Mini is a new member of the third generation of Witty Pi, and it has bonnet/pHAT form factor. After installing Witty Pi 3 Mini on your Raspberry Pi, you get some amazing new features: - You can gracefully turn on/off Raspberry Pi with a single tap on the switch. - After shutdown, Raspberry Pi and all its USB peripherals’ power are fully cut. - Raspberry Pi knows the correct time, even without accessing the Internet. - Raspberry Pi knows the temperature thanks to the sensor in the RTC chip. - You can schedule the startup/shutdown of your Raspberry Pi. - You can even write a script to define a complex ON/OFF sequence. - Monitor external voltage and turn on/off your Raspberry Pi accordingly. 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+. 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* **Technical Details** Each Witty Pi 3 Mini package contains: - Witty Pi 3 Mini board x 1 - M2.5 x 10mm plastic screw x 4 - 4mm spacer x 4 - M2.5 plastic nut x 4 - [Diagram](https://core-electronics.com.au/attachments/localcontent/5038_diagram_283277fcec2.png) - [User Manual](https://core-electronics.com.au/attachments/localcontent/5038_WittyPi3Mini_UserManual_189541922a8.pdf) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/5/0/5038-00.jpg)
