About

While working on wearables and smart textiles we figured out there is no universal low power management board for prototyping available that fits our needs. So we've decided to make our board what features USB-C fast charging, Qi wireless charging, 3.5V/5V boost on the hardware side. Via the USB-C connector you can power your project with any USB-C equipped mobile device. On the software side we provide the needed code to use the board within your projects. Complimentary you will get a mobile app for all your charging and battery statistics.
