Micro version of the short circuit finder, it includes on board programming, USB-C, lcd via ICSP

Circuit is designed to be used at 5V via USB-C, but includes a 12V DC jack so you can quickly use any 12V psu.
There are 2 test gauges pads, the longer one is designed to be soldered with a piece of 1,5mm thick solid copper wire, while the shorter one needs a long wire to act as secondary probe.
Due to the size it cannot use 4-wires probes, but you can enable it unsoldering R6 & R7, cutting the trace between those resistors, soldering the extra wires and a 2 Ohm resistor between the new wires.
