Adafruit Witty Pi 4 Mini - RTC & Power Management for Raspberry Pi

Description Witty Pi 4 Mini is an add-on board that adds real-time clock (RTC) and power management to your Raspberry Pi. It can define your Raspberry Pi’s ON/OFF sequence, and significantly reduce energy usage. Witty Pi 4 Mini is the fourth generation of Witty Pi and it has these hardware resources onboard: Factory calibrated and temperature compensated real-time clock with ±2ppm accuracy. Dedicated temperature sensor with 0.125 °C resolution. AVR 8-bit microcontroller (MCU) with 8 KB programmable flash. It's a small electronic board that can add real-time clock and power management to your Raspberry Pi. Witty Pi 4 Mini is a new member of the fourth generation of Witty Pi, and it has a bonnet/pHAT form factor. Please note, our demo photo shows it with a "2x20 Riser Header" which is NOT included! Witty Pi 4 Mini has a very similar design to Witty Pi 4, however, it doesn’t come with a DC/DC converter onboard, and it uses a supercapacitor for RTC timekeeping when no power supply is
