I am just referring to this https://www.mysensors.org/hardware/nrf2rfm69
The sockets you can find them on gearbest or aliexpress.
Of course the coverage gain is only within HW, but you can have closer nodes using normal W version.
Ok, you use this adapter to place the RFM69 module on it and let it fit in something like that?
Then I could wire it as always or should it use the 5V in the RPi instead?
