This board supports 3 different radios (beside the onboard WiFi, ESPnow of the ESP32): RFM69, RFM95, CC1101, so it can be used as mySensors gateway, mysensors node, Homematic etc. and it has a mySX connector.
@benhub - ok, there are some things you need to consider, and that is the space of the adapter.
I read now i "suggested" this adapter, but let me clear it it is not tested, maybe a language barrier from my side.
You need to consider that it fits in the board and do not crash into other compontens, like the arduino.
If it does, you maybe need to consider some other board or even build one.
