Witty Pi 3 is the third generation of Witty Pi, which adds RTC and power management to your Raspberry Pi, and can define complex ON/OFF sequence with simple script.

After installing the software on your Raspberry Pi, you can enjoy these amazing new features:

• You can power your Raspberry Pi with higher voltage.
• You can gracefully turn on/off Raspberry Pi with 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 RTC chip.
• You can schedule the startup/shutdown of your Raspberry Pi.
• You can even write a script to define complex ON/OFF sequence.
• Shutdown Raspberry Pi when input voltage is lower than pre-set value.
• Turn on Raspberry Pi when input voltage raise to pre-set value.
• When the OS loses response, you can long hold the switch to force power cut.
