The device looks pretty nice and reasonably well built. It can do 4
wire measurements.
The device itself is built around a single ST W60N10 N channel MOS
transistor (100V, 60A, 200W) and a STM8S005K6 microcontroller.

The shunt resistor is a 10mΩ wire. A very small value that explains
the rather big minimal current of 200mA (which means a voltage drop as
low as 2mV).
