Description: Nordic Semiconductor nRF24L01+. Transceiver chip operating in the 2.4GHz band. Take all the coolness of the nRF2401A and add some extra pipelines, buffers, and an auto-retransmit feature - very nice! The improved ‘+’ version of the nRF24L01 includes more features and better range!

Features:

  • Drop in compatible with nRF24L01
  • 1.9V-3.6V supply
  • 2Mbit data rate
  • New long range 250kbit option
  • Auto acknowledge
  • Auto re-transmit
  • Multiceiver - 6 data pipes
  • 32 byte separate TX and RX FIFOs
  • 5V tolerant input pins
  • Software selectable channel from 2400MHz to 2525MHz (125 Selectable channels)
  • Minimum number of external components
  • Lots of application notes and support on Nordic Semiconductor Website
  • Works well with the 16MHz SMD Crystal

Customer Comments

  • Has anyone tested this new low-data rate mode? How much more range does it buy you?

  • Just wondering: if I integrate this into a product, does my product then have to be FCC certified?

    Edit: I see your key fob, and it does not seem to require any FCC approval, so I believe I answered my own question. However, if someone could confirm this?

  • so… what do I need to use this? does it come with some base? can I hand solder this? what componets do I need to get to use it? crystal? anybody has a circuit diagram?

  • Nice chip our beta prototype of wireless flash trigger

    Hand soldered!!!!!!!!!!!!!!!

  • Has anyone transmitted packets with more than 8 bytes? I go to 9+, and no more comm… I don’t own any sweet RF equipment to debug, and my o-scope has trouble triggering on the ShockBurst packets (to at least see the envelope)..

    • Ok. The Sparkfun demo code works “out-of-the-box”, but it does not scale that way… If using the code, be sure to modify
      void tx_send_payload(char cmd)
      to something like
      void tx_send_payload(char cmd,char count)
      Do its RX friend, too.
      Other than that, if you can get over the task of soldering this little dude, awesome chip!
