Power-Monitoring-Board

This repo contains scripts, details and specifications for a board designed to measure very low power consumption in MCU's with high accuracy.

Goals

The goal here is to develop a simple current measuring board that can measure from 1uA - 50mA at high frequencies (>10kHz).

This board has to be easy to connect to a computer or a raspberry, minimizing cable connections. The idea is to have a single board with two usb ports, one to connect to the PC and the other to an IoT node with any usb connection (micro, mini, etc.).

Organization

The repo is organized as follows,

• ltspice: in this folder can be found the different spice schematics to simulate the different current measurement boards.
• scripts: in this folder can be found different c, python, etc. scripts used to read data from the current measurement circuit or calibrate the respective board.
• boards: the actual eagle schematics can be found in this folder, either for the circuits or breakout's for small smd-components.
