Describe the PCIe and UART connections through the M.2 connector, the 3.3 V supply, the W_DISABLE signals and the PCIe reset signal. Disable the onboard Wi-Fi and Bluetooth nodes when the overlay is selected. The Wi-Fi PCIe path was tested on a Shikra IQS EVK with a QCC2072 module. The overlay was applied, the link trained at Gen2 x1 and the endpoint enumerated. Bluetooth UART and HCI runtime validation is pending.
