Today we’re going to be building a mini Raspberry Pi server with a built-in UPS and OLED stats display. A Raspberry Pi makes a great server for a NAS or for media streaming, home automation, or even a home security hub for your cameras. All of these projects would benefit from having a built-in UPS to ensure that the Pi is kept running in the event of a power interruption.

It looks like a relatively simple board, with a prominent battery holder on one side, but it actually has a number of great features, including power management circuits and I2C communication, enabling low voltage safe shutdown and automatic restarts.

Power is supplied to the UPS through either USB C or a micro-USB port, with the board taking advantage of the USB 3.1 protocol to allow a higher input power through a higher charging voltage.
