Hello,

I understand the STM32f407-VG chip used on the Discovery board has 16 available ADC channels - how many are actually accessible on the board? Some of the ports seem to be assigned to e.g. the MEMS sensor, microphone and User button. Can these ports/pins still be used for A/D tasks as well? Thanks,    Angus. #adc #stm32f4 #discovery #board

One of the manuals enumerates the usable pins. A quick count suggests 9

You might be able to free up others, or pick up a simpler breakout PCB solution
