Raspi-NRF24-header

Raspberry Pi NRF24L01 header (incl. 5V to 3V3 voltage regulator and additional SPI header)

This PCB is modified version of https://www.openhardware.io/view/17/Raspberry-Pi2-GPIO-interface-for-NRF24L01.

####Usage with MySensors May be used as MySensors.org gateway, see https://github.com/mysensors/Raspberry for details.

#####Installation of MySensor's gateway

 # NRF24 Libraries
 apt install git make g++ rsyslog
 git clone "https://github.com/TMRh20/RF24.git"
 cd RF24/
 make all
 cd ..
 # MySensor gateway for Raspberry Pi
 git clone "https://github.com/mysensors/Raspberry.git"
 cd Raspberry/
 make all
 sudo make install
 sudo make enable-gwserial

#####Usage

Make your gateway available as /dev/ttyMySensorsGateway by running

sudo make enable-gwserial

If accesing by some software controller, it has to have an access rights to above device. E.g., when using FHEM controller, allow it to access /dev/ttyMySensorsGateway by

 usermod -a -G tty fhem

####PWR_SEL jumper (must be shorted correctly) Select power source by connecting a jumper to the proper pair of pins:

Short 3V3_NRF <---> 3V3PI  if using Raspberry's internal 3V3 (take care!)
Short 3V3_NRF <---> 3V3EXT if assembled LD117 regulator 
                              and feed the device via EXT_PWR_IN 5V pin (e. g. connected to Raspi 5V)

Without a proper short/jumper described above, radio is not powered!

####PWR_OUT1, PWR_OUT2 headers (optional) PWR_OUT1, PWR_OUT2 headers may be used to feed any optional external 3.3 V device
