FYI for anyone who finds this thread:
I installed the shield on a Raspberry Pi 3 and used --my-leds-rx-pin=15 --my-rf24-ce-pin=12 config parameters. The network seems to work and the red LED is blinking. I have not verified whether the LED blinks when MySensors daemon receives a message, but I would assume it does and does not just blink randomly.
All in all this shield seems like quite a nice way to install the NRF24 radio to a Raspberry Pi, so I would highly recommend it over Dupont cables.
@jvdk I agree with the point made by @evb , why would you want to wire connect the ultrasonic node rather than the usual radio connection ? You are adding levels of complexity and power demands for what reason ?
My ultrasonic water tank node (pro-mini+rfm69) is now 2 years on the same 2xAA batteries sending in levels every hour (RTC), the only problem encountered - condensation forming a drip on the face of the ultrasonic head during very low temperatures.
@virtualmkr If you say so. I'd wadger if SPI is working on the atmega4809, and just regular arduino basics, that there's not a lot of adaptation needed. But I guess to prove it I'd have to do it, and I have other priorities at the moment.
