## nRF5340 Audio DK
The first UART (UART1, P1.04, P1.05) is only available via test points (TP60, TP61, ...)
The second UART (UART2, P1.08, P1.09) is connected to the Arduino headers.

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.

### Time Sync Pinout
For time sync, Arduino header D10 is used, which uses different MCU pins on the Audio vs. the regular DK.
