nRF7002 DK v0.7.2

nRF7002 companion IC

The nRF7002 companion Integrated Circuit (IC) is connected to the nRF5340 System on Chip (SoC) using Quad Serial Peripheral Interface (QSPI) and a set of control signals.

The control signals are also available on header P24, while the QSPI by default is not connected. These can be connected to P24 by shorting the solder bridges SB20SB25.
