nRF7002 DK v1.0.0

Debug out for programming external boards

The nRF7002 DK supports programming and debugging external boards with an nRF51, nRF52, or nRF53 Series System on Chip (SoC) or the nRF91 Series System in Package (SiP).

The interface MCU on the nRF7002 DK runs SEGGER J-Link onboard interface firmware and is used to program and debug the firmware of the nRF5340 SoC by default.

To program or debug an external board instead, connect to the Debug out connector (P19) using a 10-pin cable or use P20 for custom connection.

Note: It is recommended to power the external board separately from the DK. The voltage on the external board must match that of the DK, which is 1.8V when the DK is powered through the USB connector.
