UUGear’s New Witty Pi 3 Provides RTC and Power Management to the Raspberry Pi

UUGear, known for their add-on boards, has released a new version of their Witty Pi board for the Raspberry Pi. According to the company, the Witty Pi 3 is descended from the previous version and adds an RTC and power management options for the Raspberry Pi, including the ability to define complex on/off sequences using simple scripts. The board is compatible with any Pi with a 40-pin header, which is pretty much every board in the product line.

On the hardware side, the Witty Pi 3 is outfitted with the same DS3231SN RTC chip as the previous versions, along with an ATtiny841 microcontroller for more complex applications, micro USB port (power/programming), and an onboard LM29150 LDO voltage regulator, which can handle up to 26V from a myriad of battery sources. There’s also a slot for a CR2032 battery (for RTC), and no jumpers to mess with, as all configuration is done via I2C, while a simple switch safely turns the Raspberry Pi’s power on or off if needed.

The Witty Pi 3 provides the Raspberry Pi with a myriad of different features, including the ability to cut power to the Pi and any peripherals connected to the board, and monitor temperatures thanks to the RTC chip. Users can even schedule start-up and shut down sequences, shut down the Pi if voltage drops, and force the power off using the switch if the OS loses response. The Witty Pi 3 is now available for $23 direct from UUGear’s product page.
