DFRobot Raspberry Pi UPS HAT is an uninterruptable power supply shield for the Raspberry Pi. With the addition of your own 3.7V Lithium battery, it can provide a steady 2A power source to your Raspberry Pi for an extended period of time when the system is powered off, to avoid system damage and assure safe shut down.
In addition, the product can be used to supply stable power for some applications requiring mobility such as a Raspberry Pi camera project.
A MAX17043 fuel gauge is used on this board for accurate power detection. DFRobot also employs an onboard microcontroller (MCU) for data processing. This allows the Raspberry Pi board to receive information on power capacity and battery voltage directly via I2C communication.
Five onboard LEDs for the shield can show the status of the battery capacity visually without programming.
DFRobot adopted an excellent power management solution in this Raspberry Pi UPS HAT. Over 90% power conversion efficiency and non-diode design make the shield able to remain cool even under continuous high load operation of the Raspberry Pi.
