Amplified Shunt II for mA, µA and nA Current Measurements
Description
A device for measuring small currents. Inspired by the opensourced 'µCurrent' from David L. Jones: https://www.eevblog.com/projects/ucurrent/ Advanced SMD soldering skills are required to build this project! Hints: Solder the switches in the right orientation (see video) The capacitors C3, C4 and C5 are not populated Make sure the current flow through the shunt is from + to - Measure on the low side of the load (place the shunt between load and ground) Use the tool with a low voltage and current limited power supply Start with the 1mV/1mA setting and work your way down until the signal starts to get cut off Additional needed Parts: Printed Circuit Board (upload the .zip file to your favorite manufacturer) Parts in the Partlist (see file 'Partlist_ampl_shunt_II.csv') Flexible wire for soldering the batteries to VGND (see video) Video showing operation and build: https://youtu.be/QXCb8_EW-eA
