868MHz 20mW FSK Transceiver Module (equivalent to RFM69W)

The HopeRF RFM69 is the lower cost, lower power brother to the RFM69H main radio module used in the UKHASnet system. This version allows for only up to 20mW RF Output Power, but is otherwise identical to the RFM69H. 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.

Note: This module is the Chinese distribution version of the 'RFM69W', hence missing the 'W' tag. This module is specified as being identical in functionaility and performance as well as still complaint to ETSI and FCC requirements.
