Bike dynamo charger: common questions

What microcontroller does the Bike dynamo charger use?

The Bike dynamo charger is built around the MDBT50Q-512K, from the Nordic nRF family.

How many components are on the Bike dynamo charger?

103 components, from 54 distinct parts. The full bill of materials is listed on this page.

Where can I download the Bike dynamo charger design files?

From the jekhor/bike-dynamo-charger repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the Bike dynamo charger design in my own project?

The repository has no license, so all rights stay with jekhor. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Bike dynamo charger without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
