Grand Central M4 w/ 56 Relays?

by blink515 on Thu Jul 11, 2019 2:14 pm

Hello,
I'm needing to control 56 relays for a large project and looking at using the Grand Central M4 Express. I see that it has 62 GPIO but will it support 56 digital output or will I need to look into a mux/demux board to support the number of relays needed?

Thanks.

Any of the GPIO pins are capable of operating in digital output mode.
