UPDATE: Tested in hardware now.

Update: PCB with NRF24 standart version tested in hardware.

@yveaux Sorry, i don't test the range of nodes - plan to use in the 2 floor house of 60 meters.
But you opinion is correct, this design is compromise of size, pins count and range degradate.
This is prototype, work good about 1 year:

Update status "Work in progress" (add info about tested in hardware configuration, add example of usage).

@dbemowsk
I used LP2950-5.0 in one node when feeding from 12v - about 3 months everything works quite stably.

@dakipro +1, about 2 years, running on Raspbery Pi 2B.

@ted Big thanks!
