Loic, thank you very much for your answer. Just to make it clear before doing anything stupid, the only thing I have to do is soldering a couple of wires from pins SDA and SCL, GND and +5V on the back of the ethernet module, right? I have taken a picture of the back of the board (https://goo.gl/photos/WhEEbwt2JyZGRNdY6), I assume SDA and SCL are the pins labelled as 13 and 14 respectively, correct? Thank you for your support, Paolo
Dear Paolo, You could fit a little RTC breakout module such as this one ( https://www.adafruit.com/products/264 ) into the case of the ethernet module. Pins D2 (SDA) and D3 (SCL) can be found on the 14pin connector of the ethernet module (labelled on the silkscreen on the back of the board). We will implement an RTC as standard on future versions of the Industruino. Best Regards, Loic
