Hi bennyber,

So sorry about the delay of replying.

We have provide four 2.54mm breakout pins for connecting with jumper wires on the board. So you can solder a four pin Header Connector on the board to make a breakout as following pictures show.

Then you can connect the Lego Motor Bridge to the Arduino board directly with jumper wires.

The power supply should be 7V to 12V from arduino and connect PWR to Vin, connect GND to GND from Lego Motor Bridge to Arduino.

There are two choices for the connection of SDA and SCL on Lego Motor Bridge to Arduino.

Hope this may give you some help.

Hello,

I really need to know if ‘motor bridge V2.0’ allows
to read motor feedback from Lego motors using your library?

Thank you in advance,
Benny.

Hi bennyber,

It can read motor feedback from Lego motors.

I attached a file that shows how to operate two LEGO EV3 motors using Arduino.
