Amplified Shunt II for mA, µA and nA Current Measurements

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)
