He’s trying to visualize what’s going on with the current draw of a microcontroller at various points in its operation. He figures 5 mA at 2.5 mV is in the ballpark of what he’s probing.

[Refik Hadzialic] built a cheap but accurate current probe. The probe consists of a low value resistor of just 0.1 Ω, acting as a current shunt in series with the desired load. By measuring the ...
