This small GPIO interface board allows using the NRF24L01+ radio (standard version with PCB antenna or external antenna with power amplifier) on a Raspberry PI GPIO interface.
I use this as my controller running Domoticz and it interfaces with the MySensor network via software also running on the Raspberry Pi2.
There is a small solder jumper on the bottom side.
If the middle contact and the contact marked with 3V3 are bridged, then 3V3 DC is taken from the GPIO via the 2x4 GPIO header. Use this setup when plugging the small standard radio's.
If the middle and 5V contacts of the jumper are bridged, then you need to add a two wire to connect the 1x2 pin male header to the two 5V pins of the GPIO. This second case is because the 3V3 pin on the GPIO can not carry enough power for the larger NRF24L01+ modules with power amplifier. So this board then takes power from the 5V input and steps that down to 3V3.
On the software side, install the Raspberry Mysensors gateway as per instructions below.License: CERN Open Hardware License
