| [title] Duet 3 Usage | |
| [* black] Because the CH340 drives RX to ~4.5v it doesn't communicate with the Duet 3. To remedy this you need to either cut the trace or de-solder the pad on the CH340(green) or on the ATMega(red). I would suggest de-soldering the pad on the CH340 because it's easier. | |
| [* black] In addition to the current wiring schematic you'll also need to to connect the TX from the Arduino to RX on the duet | |
| [* black] Arduino RX > Duet 3 io1.out | |
| [* black] Arduino TX > Duet 3 io1.in | |
| [* black] Arduino GND > Duet 3 io1.GND | |
| [* black] After the modifications you will no longer be able to upload a sketch using the USB port. You have to use a FTDI serial adapter and connect it to the 6 header pins next to the USB port. | |
