I am looking for a microchip or a small device that would be able to measure electrical current, preferably to 1pA, in 32 or more wires, all very near to each other?
I found this PCB https://www.ebay.co.uk/itm/124728300328 for £199 but (1) it only measures in one wire, (2) it comes with a small display and PCB.
