Housekeeping update - 1.2.2 Version numbers updated to 1.2.2 for the schematic and PCB Components identified, datasheet and descriptions updated iBOM regenerated PCB plots regenerated PCB : - only thermal reliefs on PTH, not on SMD pads - couple GND islands taken care of - couple rationalisations on the 3v3 rails

Updated opamp footprint

Externalised the Iset resistor

Comments @Alex-XNR Just confirmed with comments to educate me. I think the only point that remains open is the question of Rf and Ri ? I can't remember where I saw they were included and I can't see, to find anymore. For the higher resistance I/O I think I will try with a higher Iset resistor ? With my crappy simulator it seems to run.

Updated OpAmp CC circuit Used MOSFET instead of BJT. Reduced Vref to 100mV to increase headroom.
