I had originally assumed that the female 2x20 header in the RFM69 could be directly connected to the male 2x20 header on the Pi.
I now suspect it is not that simple because:
- when doing that the male pins on the Pi3 could not be pushed all the way into the female receptacles on the RFM69 module, and,
- the description of the pinout in the documentation makes no mention of the 2x20 header
I tried using jumper wires to connect the holes in the RFM69 to the pins on the Pi3 but they do not fit snuggly, so I am wondering what's the "right way" from doing this.
I am avoiding soldering anything to the radio as I am afraid I might damage it (and the pictures in the documentation suggest the connecting should be easier than that...
Does anyone has detailed instructions on how they connected and successfully an RFM69 module to their Pi 3? Please, be specific as possible: for instance, what kind of wiring was used to connect.
Added 2021/01/13: The problem I seem to be having is that there are 4 pins in the Raspberry Pi 3b+ that were not there in previous versions of Raspis 3s that do not let the bonnet to be connected all the way: see figure. Does anyone know what those pins are?
