this is an awesome project and after waiting for weeks to get all parts, I finally started building.
The problem I am facing is that it seems that I cannot get the board working if I use such a 8-pin connector socket. I am generally OK with NOT using such a socket for sensors that "go into production" but for some sensors where space is not an issue or for boards which I want to use for testing different NRF24s etc, I would like to make the socket work.
Does anybody have any tipps on how to make the radio reliably work with a socket? That would be awesome!

@user2684 I am also planning to build latching valve controller. But my valve is 2" to 4" and Its coil specifications are as follow:
V: 6-20Volt DC (optimal is above 9volt)
Capacitance Required: 4700uF
Coil inductance: 90mH
Pulse duration: 20 to 200mili seconds.
Do you think h-bridge will work or do you have a better suggestion for this? My goal is also to run the controller on battery and place in farm so it must be waterproof.
I'm doing quite the same project at the moment; I ordered H bridge and also some flow detectors to check if the bistable valve is really in the desired position ( open not to see a desert, closed not to flood everything)
