ANT BBPS: A small, portable and elegant open source OLED breadboard power supply (schematic, source code)

ANT BBPS displays voltage, current and power on an OLED display. It features digitally controlled current limit, wide input voltage range and up to 12 V DC output. It also has two input connections, a USB type-C connector and a screw terminal. A USB input means a battery pack can easily be used as your power source, and the screw terminals allow any other input source to be connected, such as AA and 9 V batteries, or even that old 7 V wall adapter you might have lying around.
