Witty Pi 4 enhances your Raspberry Pi with precise timekeeping and intelligent power management. Its factory-calibrated real-time clock ensures an annual error within ±2ppm, maintaining accurate time without internet access. Schedule custom ON/OFF sequences to optimize battery usage, perfect for unattended installations.The integrated temperature sensor offers 0.125°C resolution, enabling temperature-triggered actions. With its robust DC/DC converter, power your Raspberry Pi via inputs ranging from 6 to 30V, or opt for USB type C compatibility. The e-Latching power switch mimics a PC's power button, preventing data corruption from abrupt shutdowns.Compatibility spans all Raspberry Pi models with a 40-pin GPIO header. Utilizing a single I2C device design, avoid address conflicts while simplifying device management. Access Witty Pi 4 remotely through UUGear Web Interface (UWI) for convenient control. Open-source firmware and software provide customization options. https://elecena.pl/product/29498452/adafruit-witty-pi-4-hat-rtc-amp-power-management-for-raspberry-pi 2025-11-11
