MOD-IO2 is UEXT module with two relays and 7 GPIOs, which can work with any of our boards with UEXT connectors.As MOD-IO2 are stackable you can have as many IOs as you want to your UEXT board by simply plug together MOD-IO2 boards, so you can have 2,4,6 etc controllable relays.
The modules talk via I2C and the protocol is very easy. You can command the relays and read the GPIO status.
