E bike conversion kit: common questions
What microcontroller does the E bike conversion kit use?
The E bike conversion kit is built around the STM32F40X_LQFP64, from the STM32 family.
How big is the E bike conversion kit PCB?
The E bike conversion kit measures 186.9 × 129.8 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the E bike conversion kit?
175 components, from 81 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the E bike conversion kit design files?
From the ansh1113/e-bike-conversion-kit repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the E bike conversion kit design in my own project?
The repository has no license, so all rights stay with ansh1113. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the E bike conversion kit without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
