OLIMEX MOD-IO Rev A - ATMEGA16 with RELAY MODULE

MOD-IO is a stackable development board which adds analog and digital inputs and outputs to any of our development boards with UEXT. If you work with any of our development boards with a UEXT connector and you need more digital and analog inputs and outputs, you can add these by connecting MOD-IO to your development board. This board allows easy interfacing to 4 relays, 4 optoisolated digital inputs, 4 analog inputs. MOD-IO is stackable and addressable, what does this mean? It means that these boards can plug together so that you can add as many inputs and outputs as you want! E.g. 2-4-6-8 etc.! The MOD-IO has an ATmega16 microcontroller and the firmware is available for modification.
