TCM 300 / 300C / 320 / 320C 

The transceiver modules TCM 300 / 300C 
and TCM 320 / 320C enable the realization of 

highly efficient RF repeaters and transceivers 
for the EnOcean 868 MHz and 315 MHz radio 

systems.  
 

The module provides several built-in 
operating modes.  In addition repeater 

functionality (1 or 2 level) can be activated. 
Using the Dolphin API library it is possible to 
write custom software for the module. All 

module variants are in-system programm-
able.
