Modular PLC
This is the first equipment based on the Arduino technology designed for an industrial and professional use. This PLC has 21I/Os1. It also contains several communication systemswhich provide more flexibility and control. The PLC M-DUINO family offers the possibility to expand up to 127 modules through I2C, which means that you can have until 7100 Inputs / Outputs in Master-Slave connections, additionally to sensors, etc…

Programming Software
This PLC can be programmed using the Arduino IDE platform. See the Documentation menu below to download the software for free.

Instantantaneous connection and coding.
The PLC M-DUINO is programmed through the USB ports. This offers and immediate access to program, mantain and control. Also you can continuously monitor the status for all the variables, inputs, outputs, etc. It is compatible with the Arbosx and the Touchberry Pi with instantaneous connection.



Solar panels are popular because they are able to give us energy from light. When the light hits the panel solar conductor, the energy is translated into moving and electrons, creating current. In this newsletter we´ll make a simple monitoring

    Tenemos el duino en test desde hace 3 o 4 semanas. No parece que nada falle de momento. La verdad es que lo hemos estado puteando un poco como parte del proyecto en el que estamos investigando.
    Por el momento todo correcto.
