Cool.
But why do they arrange the BNCs like that?
You can't use a normal case with flat front panel with that...

Nice, it would be a 6 star device with a micro ohm meter included. Btw with that HW it is just a firmware jerk to implement it.

Yeah, but should be a real one: limit the excitation to a few millivolts, but do it with ac and read it with a lock-in amplifier. This way you don't burn away the oxidation you want to measure and don't open diodes. The ac also cancels out thermoelectric effects.

Looks like they are imitating red Pitaya..... PhuuuuCk. I hope this doesn't become a new form factor trend like the ardiuno headers.
