It is a tool that can basically measure µA/nA and therefore calculate the used energy of a low power device. Since such a tool is super handy to have around, I will also try to create my own crude low energy meter in this video. Let's find out whether a Teensy microcontroller and an Op-Amp circuit is capable of measuring µA/nA! Let's get started!
