Setup Nordic nRF24L01 RF modules to both Arduino UNO and Raspberry Pi. In my process of building a Wireless Sensor Network, I obtained a few low cost RF module from Inhaos that are compatible with Nordic Semiconductor nRF24L01.
My plans are to have these low cost RF modules replaces the wires for my sensor network on Arduino and connect them to Raspberry Pi as the IP gateway to the rest of the Internet. This entry will show you on how to setup both Arduino UNO & Raspberry Pi to connect to these nRF24L01 modules. Some basic information on these low cost RF modules, they communicate using SPI to the microcontroller and works on raw speed of 250Kbps, 1Mbps and 2Mbps. I'm using the following hardware & software:- RF modules used here :- Too many to choose from, just google for the above keyword on eBay or choose the cheapest as they sells in bulk of 10 pieces for a very low cost... *** The main differences between the regular nRF24L01+ modules and the Inhaos RF2400P modules are that the RF2400P have a higher output power of 5dBm but could not do 250Kbps speed. or. 2.4G Wireless nRF24L01+ Module. Overview The nRF24L01 module is the latest in RF modules from SparkFun.
This module uses the 2.4GHz transceiver from Nordic Semiconductor, the nRF24L01+. This transceiver IC operates in the 2.4GHz band and has many new features! Take all the coolness of the nRF2401A and add some extra pipelines, buffers, and an auto-retransmit feature - very nice! Note: We now populate these boards with the nRF24L01+. Features Voltage: 3-3.6V (recommended 3.3V) VMaximum output power: +20dBmEmission mode current(peak): 115mAReceive Mode Current(peak): 45mAPower-down mode current: 4.2uA. 2.4GHz Arduino Wireless Transceiver (nRF24l01+) from jeffmurchison on Tindie. - Don't like your order?

Nrf24L01. Nrf24L01-2.4GHz-HowTo. Having two or more Arduinos be able to communicate with each other wirelessly over a distance opens lots of possibilities:Remote sensors for temperature, pressure, alarms, much moreRobot control and monitoring from 50 feet to 2000 feet distancesRemote control and monitoring of nearby or neighborhood buildingsAutonomous vehicles of all kinds These are a series of 2.4 GHz Radio modules that are all based on the Nordic Semiconductor nRF24L01+ chip.
(Details) The Nordic nRF24L01+ integrates a complete 2.4GHz RF transceiver, RF synthesizer, and baseband logic including the Enhanced ShockBurst™ hardware protocol accelerator supporting a high-speed SPI interface for the application controller. The low-power short-range (200 feet or so)Transceiver is available on a board with Arduino interface and built-in Antenna for less than $3!
