Hi, Working up a design to use two programmable outputs plus some relay latching to control the torque convertor lockup on a gearbox. I intend using a hi/lo 5v x 4 relays module for Arduino. Is it possible to wire the In connections of the relay modules directly to pins D20/21 via J5? Just checking there are no pullup resistors etc required and this is compatible.
