How to connect an SD Card to an industrial Arduino Ethernet PLC

Installing a uSD card in an M-Duino industrial PLC


In this post, we are going to install the uSD card in an M-Duino Family PLC controller Arduino.


In order to work with a micro SD, you must have one PLC Arduino included in the next families:

Also we will need a micro SD card and a tweezer.

Checking switches

Before proceeding to connect the uSD card to the industrial controller, we must check that the uSD switch is correctly configured. We must check the communication switches and put the SD switch at OFF position (If your PLC has it) :
