Part NumberEDK 350C

The EnOcean Developer Kit EDK 350C gives the designer a fast and full overview of the powerful Dolphin platform. OEMs can develop their own energy- autonomous applications for building automation and other purposes, and assure themselves a competitive edge. The kit covers the entire product range, from energy harvesting and wireless modules to ready-made product solutions: ECO 200, PTM 2xyC, PTM 330C, STM 300C, STM 33xC, TCM 320C, USB 300C, DolphinStudio and DolphinAPI.


Detailed Description

You may also order a free extension board from Sensirion to develop an sensor application and explore the I2C interface of EnOcean Modules.

EnOcean modules offer a pre-defined  feature set for  energy  management,  data  acquisition,  data processing  and wireless  data  transmission.  User specific  applications  can  be  implemented  based on  the  application  programming  interface.

Key features 

  • Supports the international standard for energy harvesting wireless radio protocol for self-powered applications: ISO/IEC 14543-3-101) and EnOcean Alliance Equipment Profiles
  • Ready to start with EnOcean security protocol
  • Supports self-powered (e.g. sensors) and line-powered applications (e.g. switching actuator, gateway and repeater)
  • Programming & configuration slots for STM 300 on adapter, TCM 320 and STM 3xy
  • Easy prototyping of customer-specific hard-ware with patch area and pin connectors 
  • App.  notes, demos and firmware examples

Development Kit EnOcean EDK 350C

Sensor Transmitter Module STM 330C

The extremely power saving RF transmitter module family STM 33x of EnOcean is optimized for realization of wireless and maintenance free temperature sensors, or room operating panels including set point dial and occupancy button with a minimum number of external components. The module provides an integrated calibrated temperature sensor. 

Scavenger Transceiver Module STM 300C

The extremely power  saving RF  transmitter module  STM  300  of  EnOcean  enables  the realization of wireless and maintenance free sensors and actuators such as room operating  panels, motion  sensors  or  valve  actuators for heating control.
Power  supply  is  provided  by  an  external  energy harvester,  e.g.  a  small  solar  cell  or  a  thermal harvester. An energy storage device can be connected externally  to bridge periods with no  supply  from  the  energy harvester. A  voltage  limiter avoids damaging of  the module when  the supply from  the  energy  harvester  gets  too  high.


  • 3 A/D converter inputs
  • 4 digital inputs
  • Configurable wake-up and transmission cycle
  • Wake-up via Wake pins
  • Voltage limiter
  • Threshold detector
  • Application notes for calculation of energy budgets and management of external energy storages

Pushbutton Transmitter Module PTM 210C

The radio transmitter module from EnOcean enables the implementation of wireless remote controls without batteries. Power is provided by a built-in electro-dynamic power generator. Key applications are wall-mounted flat rocker switches with 1 or 2 rockers (with medial position), as well as handheld remote controls with up to 4 single pushbuttons

Transceiver Modules TCM 300C

The transceiver modules TCM 300 and TCM 320 enable the realization of highly efficient radio actors, repeaters and gateways for the EnOcean systems with 868MHz, 315MHz and 902MHz. The module provides 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. The modules are in-system programmable. 

Built-in operating modes

  • Unidirectional serial communication
  • Bidirectional serial communication 
  • 1-channel relay mode 
  • 4-channel relay mode 
  • 1-channel dimming mode 

Features accessible via API:

  • Integrated 16MHz 8051 CPU with 32KB FLASH and 2kB SRAM
  • Various power down and sleep modes down to 0.2 µA current consumption
  • Up to 14 configurable I/Os
  • 10bit ADC, 8bit DAC

Transmitter Module PTM 33xC

The radio transmitter module family PTM 330 from EnOcean enables the implementation of wireless sensors and switches without batteries. When an energy pulse is supplied (e.g. by the motion energy harvester  ECO 200 from EnOcean) an RF telegram is transmitted including a unique 32-bit module ID, the polarity of the energy pulse, and the operating status of 4 digital inputs. The RPS telegram content can be configured if other content is needed.

PTM 330 can be connected to ECO 200 via a contact spring. There are two meander structures on the PCB which allow usage of a rubber pad to set the level of two digital inputs.

USB Gateway USB 300C

USB 300  is  a  small  USB  stick  which connects  PC’s  and  smart  home  servers to  the  world  of  EnOcean  based  radio products. USB  300  is  equipped  with  the  TCM  310  transceiver  gateway module.  It  provides  bidirectional EnOcean  radio  and  bidirectional  serial  interface via USB. Radio messages  are  sent  and  received via the USB host. USB  300  provides  signal  strength. Additional control  commands  can be  sent  from  the host  to USB 300, e.g. to configure repeater functionality.
