Why the TF socket is not full connected on the GPIO?

I can see, there are two pins unconnected at the TF socket, so if these pins will be connect to the GPIO pins, we can use the TF socket easy for plug-in LoRa SX1262 chip via the SD card extension.

Note, that the Waveshare boards started use full TF socket connection.

Thanks

That's a great suggestion. We will consider supporting LoRa expansion via the TF card slot.

I also think that would be a worthwhile improvement. A full GPIO connection on the TF slot would offer greater expansion possibilities, particularly for integrating an SX1262 LoRa module. I hope SpotPear might consider this option for a future revision.
