The transceiver modules TCM 200C and TCM 220C of EnOcean enable the realization of highly efficient RF repeaters and transceivers for the EnOcean 315 MHz radio system. The module receives all signals of the EnOcean radio transmitters and makes them available at the serial port. In addition a repeater functionality can be activated. Using the API200 library it is possible to write custom software for the module.

There are two product variants: TCM 200C with 5V supply, and open drain outputs and TCM 220C with 3V supply, and digital outputs.

API200 is part of the development kit EDK100C.
