Main features are:
- 48V / 1000W
based on Atmega 328 microcontroller ("Arduino")
block or sinus + eventually sensorless commutation
60V-> 12V DC/DC converter with 7.2W output, thus around 5W for light or smartphone
android app for configuration and logging
open hardware and potentially open software
I have done a few revisions already and it is working flawlessly since several thousand kilometers.
