6. IO vs MOD IO2 MOD IO2 is a smaller input output extension module compared to MOD IO both in terms of size and in terms of functionality however in a lot of situations MOD IO2 might provide the better choice Designs which need optocouplers should consider MOD IO In a lot of the other cases MOD IO2 might be the better choice since it is possible to stack multiple MOD IO2 s over each other MOD IO has a better power supply with the option to be supplied in the range of 8 30VDC Page 5 of 28 OLIMEXO 2015 MOD IO2 user s manual 1 3 Target market and purpose of the board MOD IO2 is an extension development board which can interface other Olimex boards via UEXT connector it adds add RELAYs and GPIOs Multiple MOD IO2s are stackable and addressable The firmware allows you to interact with the board using simple commands and yet if you wish you can modify the firmware for your needs If you work with any of our development boards with UEXT connector and you need more GPIOs and RELAY outputs you can add these by connecting MOD IO2 to your development board This board allows easy interfacing to 2 relays and 7 GPIOs MOD IO2 is stackable and addressable these boards can be plugged together and you can add as many inputs and outputs as you want 2 4 6 8 etc MOD IO2 has PIC16F1503 microcontroller and the firmware is open source and available for modification The board is a very good addition to most of the Olimex boards if you need analog GPI
