well this is my project , right now im using 2 arduino nano with ethernet shield to read 3 lines Voltage on a delta instalation , 3 current sensors of 300amps for a motor , and 1 water pressure ,
all conected to a raspberry pi with domoticz
but yesterday i decide to change all , instead of 2 uno i will use a pro mini with a nrf24
so i desing two pcb
some code

havent tested with sensors yet
but looks good so far
