Based on EnOcean's innovative Dolphin system architecture, all wireless modules (315 MHz) of EDK 300C can be programmed for custom applications through the API interface. The new STM 300C scavenger transceiver is excellent for implementing energy-autonomous applications to sense temperature, light or air quality, for example. The TCM 300C and TCM 320C transceivers on the other hand are best suited for use in line-powered components such as flush-mounted actuators, repeaters or gateways.
