Input output expandable board with UEXT


MOD-IO2 is a stackable development board which adds RELAYs and GPIOs 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 GPIOs and/or RELAY outputs, you can add these by connecting MOD-IO2 to your development board. This board gives you an easy way to interface up to 2 relays and 7 GPIOs. MOD-IO2 is stackable and addressable, what does this mean? It means that these boards can stack together so you can add as many inputs and outputs as you want! E.g. 2-4-6-8 etc.! MOD-IO2 has a PIC16F1503 microcontroller and the firmware is available for modification.


PIC16F1503 microcontroller

Pre-loaded open-source firmware for easier interfacing, especially with Linux-enabled boards

ICSP 6-pin connector for in-circuit programming with PIC-KIT3 or other compatible programmer/debugger.

9-pin terminal screw connector for

7 GPIOs, 3.3V and GND PWR jack for 12VDC 7 GPIOs which could implement different functionality as PWM, SPI, I2C etc.

2 relay outputs with 15A/250VAC contacts with screw terminals
