DEV-IN-BLE-TI

Solar Development Kit with Nordic BLE (DEV-BLE-NS) System Overview The Solar Development Kit with Nordic BLE (DEV-BLE-NS) is a complete energy harvesting power management solution and Nordic nRF52832 BLE development platform. It is perfect for developers looking to design or add PowerFilms flexible solar to Nordic BLE products. This complete energy harvesting solution is capable of operating in dim indoor environments when using our Indoor Light panels, and outdoors using the Classic Application panels. The kit is able to efficiently extract power, charge a variety of storage elements, and supply power to the BLE circuit. It includes two user Solar panel leads cropped for photo selectable energy harvesting modules, one implementing the BQ25570 PMIC and the other being a dedicated Cap-Charger for batteryless Panel Specifications applications. Indoor Series Classic Application Fully compatible with Nordics development tools, the kit comes programmed with a low power optimized HRM demo.
