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

Witty Pi 4 Mini is an innovative add-on board that enhances your Raspberry Pi with a real-time clock (RTC) and power management. It introduces a new level of precision and efficiency, enabling your Raspberry Pi to operate with remarkable timing accuracy and power conservation.

Equipped with a factory-calibrated RTC and temperature-compensated crystal, Witty Pi 4 Mini ensures an annual time error within ±2ppm. This means your Raspberry Pi always knows the correct time without needing Internet access. The dedicated temperature sensor with 0.125 °C resolution allows your Raspberry Pi to act as a temperature-controlled device.

With the ability to define complex ON/OFF sequences and schedule device activity, you can optimize power usage for battery-operated systems. The e-Latching power switch offers the convenience of turning your device on/off like a computer, protecting against data corruption from abrupt shutdowns.

Witty Pi 4 Mini interfaces with your Raspberry Pi via I2C protocol, emulating a single I2C device to manage the real-time clock and temperature sensor. This design eliminates I2C address conflicts, ensuring seamless integration with all Raspberry Pi models that possess a 40-pin GPIO header.

Endorsed by UUGear Web Interface (UWI) for remote access and supported by open-source software, Witty Pi 4 Mini provides a comprehensive solution for time and power management on your Raspberry Pi, aligning perfectly with your technical needs and digital projects.
