Key features

• •PiSugar 3 adds a software watchdog function. When the function is turned on, the dog needs to be kicked regularly, which can effectively prevent the Raspberry Pi from crashing and improve the reliability of the system.
• •PiSugar 3 provides hardware battery protection like never before, limiting battery voltage to nearly 80%. When charging protection is turned on, the battery cycles life can be improved.Set up quadruple overvoltage protection function, overcurrent protection function and undervoltage protection function to ensure the safety of the Raspberry Pi, PiSugar as well as the lithium battery.
• •PiSugar 3 continues to use the pogo pin design to connect with Raspberry Pi from the back. In this way, it does not occupy the GPIO, and is compatible with other GPIO devices.
• •PiSugar 3 has full UPS functions and can set up multiple awakening methods to meet various unique project needs.
• •PiSugar 3 communicates with the Raspberry Pi through the I2C interface and is compatible with most I2C devices. In addition, the I2C communication address can be customized to avoid I2C address conflicts.
