Out of stock! Unfortunately I have decided to stop selling these transceivers so I can focus on developing my other products. If you wish to purchase more, you can get them quite cheap in quantities of 10 on eBay, or on sites like iTeadStudio.

For customers who have already purchased these transceivers from me, I will continue to offer support / answer any questions you may have regarding them.

Overview

The nRF24l01+ is a 2.4GHz transceiver that can easily be used for wirelessly communicating between two or more Arduinos (or other microcontrollers). A great, affordable way to add wireless communication to your project. They're easy to set up and example code for Arduino is included.

This listing is for one fully tested transceiver. Quantity discounts are available (see chart above for details).

These units are transceivers, meaning they act as both a transmitter and receiver. No need for a separate transmitter and receiver like with other wireless units. You can have multiple units communicating with each other, and even use them to create a mesh network.

Details

• Easy to use with Arduino (example code and libraries included)
• Only requires 5 digital pins (SPI - pins 11, 12, 13, and two user-defined pins)
• 150 to 250 foot max range (depending on various conditions including walls and other objects)*
• Up to 2Mbps on-air data-rate options
• Up to 32 byte payload
• Power requirements: 1.9V - 3.6V **
• 5V tolerant data pins (for use with Arduino)
• Low current requirements ( < 13mA during Tx and Rx / 900nA deep sleep mode)
• SPI communication

Example Code

A couple of folks have written some great Arduino libraries for these transceivers, so getting them up and running is pretty easy. Here are some of the libraries that I recommend:

• RF24
• RF24Network (for creating a mesh network with the nRF24l01+ transceivers).
• Mirf

Shipping Notes

All orders will be shipped by Canada Post. Please read my store policy for information on insured vs uninsured shipping options. If you do not see an insured shipping option at checkout and would like it, then please contact me. The delivery time estimates for insured shipments can be found here while the estimates for uninsured shipments can be found here. Note that these are not a guarantee.

I know that waiting for packages sucks, so all orders will ship as soon as possible! (Within 1 business day unless otherwise noted. Orders made before 7:00 AM EST will be shipped the same day!) Note that orders made on the weekend or on Canadian public holidays (both national and Ontario holidays) will not ship until the next business day as per Canada Post Delivery Standards.

Product Notes

This product is not designed by me.

* Transmission range listed is under ideal conditions and is not a guarantee. For the best transmission range, minimize the amount of objects between the transceivers.

** Data lines are 5V tolerant but unit must only be powered with between 1.9 and 3.6v (eg, from the 3.3v pin on Arduino). Using more than 3.6v may cause damage to the transceiver.

*** These transceivers are run through a basic transmit/receive communication test to ensure that you don't get defective units.
