#Witty Pi
|
||
|
|
||
|
Witty Pi is an extension board that adds realtime clock and power management to your Raspberry Pi.
|
||
|
|
||
|
You can turn on/off your Raspberry Pi with a single tap on the button on Witty Pi, and the power supply for Raspberry Pi and all its USB peripherals will get fully cut after the shutdown.
|
||
|
|
||
|
Witty Pi has a CR2032 backed realtime clock (DS1337) on board, and can keep time for Raspberry Pi when it is off. You can schedule next shutdown/startup of your Pi via the software. A user-defined schedule script could be used for complex use case, which requires scheduling multiple shutdowns and startups at different moments.
|
||
|
|
||
|
You can use the two commands below to install software for Witty Pi:
|
||
|
|
||
|
```bash
|
||
|
wget http://www.uugear.com/repo/WittyPi/installWittyPi.sh
|
||
|
|
||
|
sudo sh installWittyPi.sh
|
||
|
```
|
||
|
After the installation is done, reboot your Raspberry Pi and your Witty Pi is ready to go.
|
||
|
|
||
|
Witty Pi supports all Raspberry Pi models that have 40-pin header, including A+, B+, 2B, 3B and Zero.
