Pmod RF2: IEEE 802.15 RF Transceiver

(1 review) Write a Review

Please note: the Pmod RF2 is no longer in production. Once the current stock is depleted, it will be retired.

The Pmod RF2 adds RF communication through the Microchip® MRF24J40 IEEE 802.15.4™ 2.4GHz RF transceiver module. By communicating with the device through SPI, users can transmit data at speeds up to 625 kbps through the ZigBee®, MiWi™, and MiWi P2P software stacks all available for download at the Microchip website:

  • IEEE 802.15-compliant RF transceiver
  • Supports ZigBee, MiWi and MiWi P2P wireless networking protocols
  • ISM band 2.405-2.48 GHz operation
  • Integrated 20 MHz and 32.768 oscillator circuitry
  • Small PCB size for flexible designs 1.2“ × 0.8” (3.0 cm × 2.0 cm)
  • 12-pin Pmod connector with SPI interface
  • Follows Digilent Pmod Interface Specification Type 2A
  • Pmod RF2
  • Custom antistatic Pmod packaging

Quickly find what you need to get started and reduce mean time to blink.

    Not trivial. MiWi takes 20k space I read. It's not available for MPLABX and it's proprietary. You could probably get a simple beacon-enabled system running on less than 2k ROM for RFD and maybe twice that for PAN-coordinator FFD in a simple network. It's definitely worth getting two and a logic analyzer to explore the wireless network protocol. I could have never got it up without the logic analyzer. I don't see how printf's could do it. I
