REH-3.31.8-EVM-1 Series

  • Evaluation platform for REH-3.31.8 energy harvester module
  • Supports rechargeable Li-Ion battery or supercapacitor as energy storage
  • Backup coin cell battery holder footprint and input for uninterruptable operation
  • Easy setup and evaluation

The REH-3.31.8-EVM-1 allows a quick evaluation of the REH-3.31.8 energy harvester module. It contains all the necessary easy-plug-in connectors to connect the energy source, energy storage element, twin output voltages and an external backup battery (if used). The PCB footprint includes pads for a space-saving CR2032 battery holder to serve as an on-board backup battery, if required. If a primary cell back-up battery (1.5VDC to 4.5VDC) is fitted, the REH-Module will automatically switch over to the back-up supply if the energy arvesting input fails to maintain an uninterrupted output.

With the REH-3.31.8-EVM-1 evaluation board, it is possible to configure all of the features of the REH-3.31.8 module such as selection of the type of the storage element (rechargeable battery or supercapacitor), set the backup battery switch-over threshold voltage and to independently enable either or both outputs. All input and output signals of the module are easily accessible for test probes.
