The Witty Pi 3 RTC & Power Management for Raspberry Pi Board is the third generation of Witty Pi, and it is the descendant 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, including A+, B+, 2B, Zero, Zero W, 3B, 3B+, 3A+ and 4B.
Comparing to Witty Pi 2, Witty Pi 3 uses the same RTC chip (DS3231SN) and introduces a new micro-controller (ATtiny841), which allows it to behave smarter and handle more complex situations. Thanks to the new on-board LDO voltage regulator (LM29150), Witty Pi 3 can accept DC voltage higher than 5 V (up to 26 V, depends on the load and heat sink).
