Description:

Witty Pi 3 is the third generation of Witty Pi, and it is the upgraded version of Witty Pi 2. It adds realtime clock (RTC) and power management to your Raspberry Pi, and can define complex ON/OFF sequence with simple script. Witty Pi 3 supports all Raspberry Pi models with 40-pin header such as 4B, 3B+, 3B, 3A+, 2B, B+, A+, Zero, Zero W.

Witty Pi 3 uses the same RTC chip (DS3231SN) as compare to the Witty Pi 2 and it comes with a new micro-controller (ATtiny841), which enables it to act smarter and handle more complex situations. Thanks to the new on-board LDO voltage regulator (LM29150), Witty Pi 3 can acknowledge DC voltage higher than 5V (up to 26V, depends on the load and heat sink).
