Description

Add 2 relays and PWM/Analog/GPIO via I2C interface

MOD-IO2 is a stackable development board to add RELAYs and GPIOs to any of your development boards using I2C bus. It is even more easy with UEXT capable board, just plug it works with any of boards exposing UEXT connector.

With MOD-IO2, you will have more GPIOs (PWM, analog input, digital input/output) and/or RELAY outputs! Just connect the MOD-IO2 through I2C bus to your development board and you will be able to use the 7 GPIOs and 2 Relays with an affordable I2C protocol. Libraries are available for Arduino and MicroPython plateform.

The MOD-IO2 is stackable and addressable. This means that these boards can stack together (or with other UEXT board) so you can add as many inputs and outputs as you want! The MOD-IO2 is propelled with a PIC16F1503 microcontroller and the open-source firmware is available for modification.

What's UEXT ?

UEXT connector UEXT is a connector carrying I2C bus + SPI bus + Serial + 3.3v power. It use a very standard 10 Pin IDC connector. It is quite easy to add sensors and extension board with UEXT connector... just plug it or wire it with IDC ribbon! Great.

Our favorite is the carrying of I2C bus allowing to easily add several sensors and expansion board. On the other side, SPI would be welcome for fast data transmission like remote screen. The serial connexion could be made compatible with RS-232, RS-422, RS-485, DMX512, MIDI by using appropriate level-shifting circuitery.

This connector is usually available on almost Olimex's product including nano computers. It is a great way to add extension boards on products like ESP8266 WiFi microcontroler or microcontroler board. UEXT is suited for prototyping, school learning (no need for iron) and industrial solution (Olimex produces Industrial Grade boards).

See our UEXT expansion or all products exposing UEXT connector on the shop, the Olimex's UEXT collection, Wikipedia to learn more about UEXT.
