The RFM69CW is a pin-compatiable replacement for the RFM12B. The module is manufactured by HopeRF with SEMTEC silicon.
With the updated RF12 driver from JeeLabs the RFM69CW can be backwards compatible with the RFM12B
Up to 300Kbps
13dBm Output Power
Up to 28 nodes per network
Up to 250 different network groups
Hardware Encryption Options
3 different ISM band frequencies: 433Mhz (worldwide), 868Mhz (Europe), 915Mhz (USA & Australia only) . Note: frequency of a module is set in software, for best performance the frequency set should match the intended hardware frequency of the module.
FCC and ETSI complient
SPI interface
1.8-3.6V supply voltage
Low power – 0.1µA standby current
