[Aleksejs Mirnijs] needed a tool to accurately measure the power consumption of his Raspberry Pi and Arduino projects ... Since most SBC projects require a USB hub anyway, he designed a smart ...

The USB interface is being increasingly used as a power supply and charging port for ... resistive divider that has a range of up to 6V. An Arduino sketch reads voltage and current data on the ...

It's like a shrunken version of the Arduino Leonardo as it features the same ATmega32U4 microcontroller, micro-USB port ... is the lack of power barrel connector on the Micro.

The Arduino Nano and Raspberry Pi Pico support different input voltages, so they also use different power sources. However, they can both be powered with a 5V supply via their onboard USB ports.
