EnOcean TCM 300U RF Transceiver Radio module 315MHz, 2.6 → 4.5V

The EnOcean transceiver modules TCM 300 and TCM 320 enable the realization of highly efficient radio actors, repeaters and gateways for EnOcean ISM-band systems. The modules have several built-in operating modes. In addition a repeater functionality (1 or 2 level) can be activated. Using the Dolphin API library it is possible to write custom software for the module. Both modules are in-system programmable.

Batteryless Wireless Applications

EnOcean manufacture a range of transmitter and receiver products that operate in the 868MHz area of the ISM band. These devices are typically very efficient in terms of the power supply requirements and are used to send short messages.,The advantages of EnOcean technology are clearly illustrated through applications such as electrical control which eliminates the need for external wired connections and batteries.,Suitable for limitless applications where maintenance free and flexible switching needs to be installed without drilling, cabling and reconstruction costs.,Power in the transmitters is also created for "FREE" using energy harvesting techniques to create energy from the push button switches or solar power for its sensors transmitters.,Radio systems based around EnOcean technology can be formed into star, mesh, or hybrid topology networks, and are a good complement to ZigBee systems, typically in building automation and remote sensor applications.
