EnOcean 2 click carries the TCM 515Z transceiver, based on the 2.4 GHz IEEE 802.15.4 radio standard. The click is designed to run on a 3.3V power supply. It communicates with the target microcontroller over UART interface.

This low-powered wireless module is intended for use together with EnOcean’s range of energy harvesting modules. These are miniaturized converters that harness energy from motion, light or temperature differences, that come in the form of self-powered, battery-free wireless switches, sensors and actuators.

TCM 515Z

TCM 515Z enables the realization of line-powered actuators, controllers, and gateways communicating based on the 2.4 GHz IEEE 802.15.4 radio standard.

It provides a transparent radio link between EnOcean 2.4 GHz devices and an external host connected via the standardized ESP3 interface (EnOcean Serial Protocol V3).

TCM 515Z works on a 2.4 GHz frequency for ZigBee systems.

EnOcean Serial Protocol 3.0 (ESP3)

ESP3 is a Point-to-Point protocol with a packet data structure.

The maximum size of transferred data is 65535 bytes. Compared with ESP2.0, that has the maximum of 25 bytes, it’s a considerable improvement.

Onboard antenna

TCM 515Z receives and transmits data based on a 50Ω whip antenna connected to its ANTENNA input.
