Hello, we are new with Arduino products and have little knowledge of electronics, we currently want to plug the card into the control Board of the Arduino Robot, the card has 4 pins (RX,TX,GND and 5v). Thought about using the pins for the LCD Module, but we are unsure where exactly they whould go, suggestions would be accepted thankfully because we´ve come across a tutorial on how to connect the card with an Arduino 1 but the pins dont match.
We do know how to at least plug in the power and GND, but our doubts reside on where does the RX and TX should go.
