Hardware description
5.7 nRF52840
An nRF52840 Bluetooth/IEEE 802.15.4 System on Chip (SoC) is included on the nRF9160 DK board.
This device has two functions:
• nRF9160 DK board control
• Bluetooth/IEEE 802.15.4 network processor

5.7.1 nRF9160 DK board control
The nRF52840 controls analog switches on the nRF9160 DK, enabling routing of some of the nRF9160
GPIO pins to onboard functionality, for example LEDs, or the regular GPIO interfaces.
For details on which GPIOs on the nRF9160 can be routed by these analog switches, see the table below.
