Overview

Comes as either bare PCB or kit options. All through-hole components so no special soldering tools or skills required.

Details

RFX nRF24L01+ Proto Shield. This nRF24L01+ shield with prototyping area is a neat and convenient way to add a nRF24L01+ module to an Arduino/X:duino project, saving on the point-to-point wiring.

It supports the standard Arduino shield header layout, as well as a second breadboard compatible (i.e., proper 0.1" pitch grid-aligned) header layout, so you can also easily connect the nRF24L01+ shield to common 50mm (or wider) proto board.

Shield has two 8 pin (4x2) headers for plugging in a nRF24L01+ module, one header providing connection to the hardware SPI pins D11-D13, and the other to an alternative set of pins, D4-D6, for a software SPI ("bit banging") implementation if preferred. IRQ pin is set at D2, CE is D3 and CSN is D7.

Also has provision for a 3x2 connection header to the ICSP hardware SPI pins, which is required if accessing hardware SPI for Mega, Leonardo, Due. (There is provision for disconnecting the D11-D13 pins from the hardware SPI header in this case, if needed.)

Three power supply configurations are available via a jumper setting (or soldered link, if preferred). If using the 3v3 voltage regulator, power can be sourced from either 5V or VIN pins, or if the dev board can provide a sufficient supply on the 3v3 pin, the shield voltage regulator can be dispensed with entirely.

Use Cases

So lots of flexibility and configuration options with this shield! Combined with the generous prototyping area, this can make deploying of nRF24L01+ enabled projects faster and neater.

Designed originally as part of the Radio for X:duino (RFXduino) project, but these boards can be used with any software library that support nRF24L01+, as the shield hardware is not RFXduino library specific in any way (although that's always a good choice, of course :-).

Shown in photos as populated shield, and installed on various dev boards: Arduino Uno, Mega2560, Due, and the PJRC Teensy 3.0.
