Pin on J8Pin on WBZ450PE ModuleDescription
1GNDGround
2PB6, SERCOM1_PAD2UART RTS pin
3NC No connection
4PA6(2), SERCOM1_PAD1UART RX pin
5PA5(1), SERCOM1_PAD0UART TX pin
6PB0, SERCOM1_PAD3UART CTS pin
Note:
  1. In J8, PA5 is also shared with PKOB4. Depopulate R1 to isolate the connection to PKOB4.
  2. In J8, PA6 is also shared with PKOB4. Depopulate R2 to isolate the connection to PKOB4.
