Hi.
We have a requirement for a lot of 24V digital I/O pins. The 91 available on the Portenta H7/C33 via the high density connectors is a good number for us. From what I have read I can't see anything to suggest that the Portenta Machine Control module allows any more GPIO than the terminals already fixed on the top of the board, unless I have missed something? Is there any way of accessing extra GPIO pins from the high density connectors or from the castellated pins via the machine control module?
My alternative I think will be to use a C33 and build a PCB to allow use of the maximum number of GPIO pins from the high density connector, something similar to this but for 24V:
If anyone may have carried out a similar project I'd be interested to hear about it.
