To use UART 1 via Arduino headers, the virtual UART of the J-Link probe needs to be disabled, e.g. with the JLink Configuration Tool.
### UART 1 + Time Sync Pinout
### UART 1 Pinout
Signal direction as seen from the nRF5340.
| PIN | Arduino | nrf | Direction |
| PIN | Arduino | MCU | Direction |
|----------|---------|-------|-----------|
| TX | D0 | P1.09 | out |
| RX | D1 | P1.08 | in |
| RTS | D7 | P1.11 | out |
| CTS | D8 | P1.10 | in |
| Timesync | D10 | P1.01 | out |
### Time Sync Pinout
For time sync, Arduino header D10 is used, which uses different MCU pins on the Audio vs. the regular DK.
