RFM69CW 433Mhz

RFM69CW RF transceiver module

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
