Dear Lattepanda,
I understand that the Arduino side of the LP board is based on Arduino Leonardo which only had 1 set of TX, RX pins for serial communication. I need 2 sets of these pins for my current project.

Is there any way to have 1 more set of TX RX pins for the LP board, such as connecting an using an external device like FT232RL USB to Serial Breakout board?
