Orders can take 2-3 weeks to ship. Please contact us for a more specific shipping timeline.

Fully powered by PowerFilm’s Indoor Light Series solar, the Bluetooth Indoor Solar Development Kit is a wireless sensing module that collects data from a variety of sensors and sends it to a connected mobile device via Bluetooth Low Energy (BLE). Ideal for indoor environments, the LES100 kit uses a nano-power energy harvester to operate down to 200 lux and below. The integrated power management features battery charging with over/under voltage protection and a regulated output voltage rail.


This development kit is meant to be the first building block of any IoT sensing project or idea. The wireless MCU is broken out so additional sensors and components can be added easily. This open source design accelerates the development process by making solar power simple.
