because I want to monitor the serial output of my mbilly board (without causing a reset), I try to use the Grove connector nr 3 which are the same I/O lines that are connected to the USB port.
For security I didn’t connect the 5V line.
So I connected for grove nr 3
grove GND (black) => USB GND (black)
grove RX (white) => USB D- (white)
grove TX (yellow) => USB D+(green
grove +5V (red) left free => USB +5V (red) left free
I also swapped the RX and TX but no progress. I don’t see the output
How can I monitor the USB port of the Mbilli ? Using Arduino Serial port monitor ? or Putty ?
