Hello.

@Mega mozg

I know its possible to use pro micros 5v to power up mcp 3208 however in your original pro micro and extension board you have used external 12v power supply converted to 5v to power up both mcp 3208.

My knowledge of electronics is limited and i can only guess why did you do that way.
Am i correct guessing that the only reason to use external power supply (stable 5v) to mcp3208 is to get highest sampling rate from the chip.

Thanks

@tirta

i am using 'ebay' pro micro and it works just fine, just make sure its pro micro and not any 'other'micro
