EnOcean click carries a TCM 310 transceiver, which is a bidirectional gateway for EnOcean’s 868 MHz radio systems. The click is designed to run on a 3.3V power supply. It communicates with the target MCU through UART (TX, RX pins), with additional functionality provided by RST and EN pins.
Note: Modules with 868 MHz frequency are suitable for Europe and other countries adopting R&TTE specification. Versions of EnOcean click covering different frequency bands will be available in the future.
TCM 310 transceiver
This low-powered wireless module is intended for use together with EnOcean’s range of energy harvesting modules that include self-powered, battery-free wireless switches, sensors and actuators.
Essential features
EnOcean offers a range of modules compatible with TCM 310. Those are miniaturized energy converters that use the surrounding environment — motion, light or temperature differences — to harness enough energy to send a wireless signal to the receiver onboard EnOcean click.
The TCM 310 module can also be set up as a repeater to extend the range of the signal. You can then develop various battery-free switching systems, data loggers and similar.
Onboard antenna
EnOcean click features a small high-performance 868MHz chip antenna onboard so no external antennas are required.

Pinout diagram
This table shows how the pinout on EnOcean click corresponds to the pinout on the mikroBUS™ socket (the latter shown in the two middle columns).
Programming
The function sends ESP3 packet header and data over UART interface to an EnOcean module.
01 uint8_t sendMessage(ESP3Pack* esp){ 02 03 uint8_t i=0; 04 05 if((esp->header.dataLength || esp->header.oppDataLength) == 0) 06 { 07 return -1; 08 } 09 10 UART2_Write(esp->syncByte); 11 UART2_Write((esp->header.dataLength & 0xFF00)>>8); 12 UART2_Write((esp->header.dataLength & 0xFF)); 13 UART2_Write(esp->header.oppDataLength); 14 UART2_Write(esp->header.packetType); 15 UART2_Write(esp->headerCRC); 16 17 for(i=0; i < esp->header.dataLength; i++) 18 UART2_Write(esp->dataESP3[i]); 19 for(i=0; i < esp->header.oppDataLength; i++) 20 UART2_Write(esp->optData[i]); 21 22 UART2_Write(esp->dataCRC); 23 24 return 0; 25 }
