Nichicon SLB Battery Evaluation Board

Nichicon SLB Battery Evaluation Board is a printed circuit board assembly (PCBA) that features all required components to quickly operate and evaluate an energy harvesting concept. This eval board utilizes an ultra-small lithium titanate battery (LTO) as the energy storage device. Power management for the harvesting is operated with the integrated circuit (IC) AEM30330 from E-Peas. The E-Peas offers an ultra-low power and high-efficiency PMIC for energy harvesting where users can configure specific setups, allowing the usage for a wide range of IoT harvesting applications. Nichicon SLB Battery Evaluation Board has space for up to three parallel SLB batteries, DC and AC harvesting sources, and dimensions of 110mm x 60mm.
