868MHz 100mW FSK ISM Transceiver Module (equivalent to RFM69HW). 

The HopeRF RFM69H is the main radio module used in the UKHASnet system. The 'RFM69H' version allows for full 100mW while the 'RFM69' version only goes up to 20mW output power. Interfacing is via SPI and there is libraries and example code for use with AVR, Arduino and ARM microprocessors. The modules will require soldering and it is recommended to either use a PCB (check out our kits) or stripboard (UKHASnet Wiki) to integrate it into your node. 

Datasheet: RFM69H-V1.3.pdf


  • +20 dBm - 100 mW Power Output Capability
  • High Sensitivity: down to -120 dBm at 1.2 kbps
  • High Selectivity: 16-tap FIR Channel Filter
  • Bullet-proof front end: IIP3 = -18 dBm, IIP2 = +35 dBm
  • 80dB Blocking Immunity, no Image Frequency response
  • Low current: Rx = 16 mA, 100nA register retention
  • Programmable Pout: -18 to +20 dBm in 1dB steps
  • Constant RF performance over voltage range of module
  • FSK Bit rates up to 300 kb/s
  • Fully integrated synthesizer with a resolution of 61 Hz
  • FSK, GFSK, MSK, GMSK and OOK modulations
  • Built-in Bit Synchronizer performing Clock Recovery
  • Incoming Sync Word Recognition
  • 115 dB+ Dynamic Range RSSI
  • Automatic RF Sense with ultra-fast AFC
  • Packet engine with CRC-16, AES-128, 66-byte FIFO
  • Built-in temperature sensor
  • Module Size: 19.7x16mm 

Note: This module is the Chinese distribution version of the 'RFM69HW', hence missing the 'W' tag. This module is specified as being identical in functionality and performance as well as still complaint to ETSI and FCC requirements. The RFM69HW datasheet for comparison can be found at: RFM69HW-V1.3.pdf
