My RF24L01+ modules

The Nordic >nRF24L01+ is a highly integrated, ultra low power (ULP) 2Mbps RF transceiver IC for the 2.4GHz ISM band.

I bought a set of cheap modules to try out some time ago. Talk of these chips has also come up at Tarlab recently. The short range and small packet seem fitting for collecting occasional readings and sending control commands. There is no security whatsoever. Supposedly the chips run on fairly little current and work well on battery power. Having a microcontroller with similar abilities would be convenient. MSP430 and STM32 appear nice at a glance.

The plan


Threw together a kicad nrf24l01+ component for a start. Note pin 1 location depending on board orientation. This was made from other docs and unverified. A plain schematic might help with initial wrapup. A 2x4 pin header should work as a footprint/module.

Software and firmware

TBD. I don't like working without hardware to test on. Browsing inspirational resources for a start.
