nRF5340-DK

lbuild config: modm:nrf5340-dk

Nordic Semiconductor nRF5340 Development Kit.

This BSP supports both cores and Board::initialize() configures the selected core with these settings:

  • Application core target: nrf5340-xxaa@app
  • 128MHz CPU clock frequency.
  • MODM_LOGGER initialized at 115.2kBaud on UARTE1 (P1.01 TX, P1.00 RX).
  • Owns LED1/LED2 and Button1/Button2.

  • Transfers selected GPIO ownership to the network core.

  • Network core target: nrf5340-xxaa@net

  • 64MHz CPU clock frequency.
  • MODM_LOGGER initialized at 115.2kBaud on UARTE0 (P0.20 TX, P0.22 RX).
  • Owns LED3/LED4 and Button3/Button4.

The default board core in board.xml is the application core (nrf5340-xxaa@app). To use this board with the network core you must inherit and then overwrite the the modm:target with nrf5340-xxaa@net.
