On the NanoPC-T6 which PIN of the Debug UART is closest to the EDGE of the BOARD, #1 or #3?

On the NanoPC-T6 which PIN of the Debug UART is closest to the EDGE of the BOARD, #1 or #3 ?

  • Debug UART Pin Spec

3.3V level signals, 1500000bps

Pin# Assignment Description
1 GND 0V
2 UART2_TX_M0_DEBUG output
3 UART2_RX_M0_DEBUG intput

I can not find the ORIENTATION (Pin #1) of the Debut UART on the PCB or Silkscreen

Thank you for your time and attention.
