Description: Miniature RF (MiRF) 2.4GHz transceiver modules with built in antenna designed around the Nordic Semiconductor nRF2401A with high sensitivity and good range. These units are a SparkFun exclusive; small in stature, big on performance, all wrapped up in a user friendly package. Units come with an empty 0.1" spaced footprint ready for a straight header, right angle header (recommended), or your own wires/umbilical cable.

Note: These are sold as single units. We recommend ordering two for a complete link.

Customer Comments

  • This module would be awesome with an SMA connector, wouldn’t it? This antenna looks too uncomfortable to put around in a case under the rain, and the other module with the on-chip antenna looks like having problems with range.

  • 0dBm is 1mW, right?

  • Is it possible to transmit data from a uC to PC and vice versa if on the controller side I use a nRF2401A and on the PC I use a WRL-09019 with nRF24L01 on it ?
    Thank you.

  • Has anyone ever gotten this to work with arduino successfully ? I tried using the library available for NRF2401 on their website but it doesn�t work.

  • how much do these weigh?

  • Last batch use the nFR24AP1 not the nFR2401A chip. It seems protocol are not the same I think.
