La carte Click Board™ EnOcean 2 embarque l'émetteur-récepteur TCM 515Z, basé sur la norme radio IEEE 802.15.4 à 2,4 GHz. La carte Click Board™ est conçue pour fonctionner sur une alimentation de 3,3 V. Elle communique avec le microcontrôleur cible via l'interface UART.
Ce module sans fil à faible consommation est destiné à être utilisé avec la gamme de modules de récupération d'énergie d'EnOcean. Il s'agit de convertisseurs miniaturisés qui exploitent l'énergie du mouvement, de la lumière ou des différences de température, sous la forme d'interrupteurs, de capteurs et d'actionneurs sans fil auto-alimentés et sans batterie.
The EnOcean 2 Click Board™ 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.

Software Support
Code examples for the EnOcean 2 Click Board™, written for MikroElektronika hardware and compilers are available on Libstock.
The library implements EnOcean Serial Protocol 3. It can be used for communication between a host and an EnOcean module. Recieved packets, if valid, are forwarded to a user via the callback function.
The demo demonstrates the library functionality using the EnOcean 2 Click Board™ and PTM215ZE Pushbutton Transmitter Module. When the user pushes the button, a corresponding LED is turned on or off.
