SLB Series Energy Harvesting Evaluation Board

SLB Series Energy Harvesting Evaluation Board

Nichicon “SLB” series are “Small Lithium Titanate Rechargeable Batteries” ideal for powering IoT systems. The EVSLB-EHEP02A is an evaluation board that allows users to test the SLB series with combining various types of energy harvesting devices. With a built-in power management IC, the power collection efficiency can be optimized according to the energy harvesting element used. It is also equipped with 2 types of power output, it can be used properly according to the application. The EVSLB-EHEP02A provides an easy way to configure the energy harvesting powered source.

  • Solar (DC), vibration power generation (AC), etc. Input from various harvesters are possible
  • Supports power collection settings optimized for harvester characteristics
  • Compatible with all 5 types of SLB series
  • Supports 2 outputs (SLB direct / 3-5V)
  • High customizability
