Description
A power management module with RTC clock designed for the Raspberry Pi. The board is equipped with an ATtiny841 microcontroller which controls the operation of the module. The Witty Pi 4 allows scripting of power-up and power-down sequences for the minicomputer and provides up-to-date date and time without internet access and allows temperature measurement thanks to the built-in thermometer chip. It is designed to operate with a 3.7V lithium (ion or polymer) battery and can be used as an uninterruptible power supply (UPS). The module is compatible with all versions of Raspberry Pi with a 40-pin connector. It has a built-in DC-DC step-up converter. It will be used in projects that require more advanced functions to switch the device on and off depending on the supply voltage, for example.
Features
- Real-time clock RTC PCF85063A (I2C interface)
- ATtiny841 microcontroller
- Built-in MP3423 DC-DC step-up converter
- Power supply: 5 V (USB type C) or 3.7 V LiPo battery
- Option to switch the Raspberry Pi on/off using a button
- Time synchronisation possible between real-time clock and Raspberry Pi
- Temperature measurement: LM75B
- Ability to create scripts to define a complex on/off sequence
- Output current: 3 A
- Current consumption in stand-by mode: 0.3 mA
- Dimensions: 65 x 30 x 7 mm
Kit contains
- Witty Pi 4 L3V7 board
- Screw set
- Cable
