MySensors SMD gateway (nRF24L01, 2.4GHz) designed to fit Raspberry Pi GPIO ports. Shrunk SMD version of GertSanders Raspberry Pi2 GPIO interface for NRF24L01+.
Two different models are available, only difference being the PCB shape.
Regular version is the smallest form factor available. Radio module is straight with GPIO pins.
A Pimoroni version is also available, designed to fit inside the popular Pimoroni cases designed for the original Raspberry Pi model B, such as Pibow.
This version can be ordered directly assembled($20) on openhardware.io
Gerber files are included so you can order these PCB at your favorite PCB fab house and solder the few components yourself. For an easy ordering process you can directly order these PCB without having to do anything else:
Plug the Gateway module to Raspberry Pi Pins 17 to 24 and follow the instructions on MySensors website to compile the code.
