I ordered the MNT Pocket Reform Headset/Switch Board 2.0 and I have a surplus cable, see picture. I tried to understand where it belongs so I took a look at the DIY Assembly Guide . It seems step 19 (page 17) show the Headset/Switch Board 1.0 while step 20 (same page) shows the Headset/Switch Board 2.0. I guess step 19 would be the step where the correct location would be shown. I tried to find the correct connector on the mainboard but failed. I do have a slot for the WiFi card on the mainboard so I am fine, but still the guide might need fixing (or I am missing something).
This cable plugs into the RCORE carrier board on which the RK3588 SoM is mounted. The connector is underneath the SoM board, between its high-speed connectors.
Note the connector in this image that says “WiFi/BT”, to the left of the MNT logo near the left edge of the carrier board.
