Hi, @Idahowalker. I'm using pins 16, 17, 18, 19, 21 and 22 as output pins for the relay module (which is one with optoisolators). What other pin do you suggest me to use instead of 33 that has a pull-up resistor? are the other 5 pins ok to use?

Thank you for your help.

The other pins on portA, pins less then 33, have pullthingies. Pin 5 which is less then 33 has a pullthingy.
