Arduino UNO NRF24L01+ Shield is specially design to add wireless connectivity to Arduino UNO.

This shield is design to make MySensors available to people with basic hardware knowledge and skills. Its saves time and avoid messy wiring connections.

Is easy to use just stack the shield on the top of the Arduino UNO connect NRF24L01+ to the shield upload MySensors code, that it.

Known issues with the design:

  1. One of the mounting holes are not aligned to Arduino hole, will be changed in future.
  2. The SMD pads for NRF24L01+ are not comparable for all NRF24L01+ modules. Different vendors have different pinout of this modules. Link for compatible SMD modules will be provided.

Be advised this shield cannot be used as MySensor Ethernet Gateway, the wiring are different. There exist other project for gateway. https://www.openhardware.io/view/695/Arduino-Uno-Radio-Shield-SerialEthernet-GW

The shield use this pins of the Arduino UNO:

Pin D2 NRF24L01 IRQ

Pin D9 NRF24L01 CE

Pin D10 CSN

Pin D11 MOSI

Pin D12 MISO

Pin D13 SCK

The Pins D10 to D13 is 4wire SPI interface. On the theory those pins can be used to connect another SPI device on the interface, i never test more than one device on the SPI line.

Pin D2 is IRQ is a Interrupt Request Line to the micro-controller.

Pin D9 is Chip Enable for the NRF24L01 Module.

Pins D2 and D9 cannot be used for other devices and sensors.
