BldcDriver: common questions
What microcontroller does the BldcDriver use?
The BldcDriver is built around the IP2325_5M_WHJC, from the STM32 family.
How many components are on the BldcDriver?
101 components, from 46 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 BldcDriver design files?
From the dwanpo/balancer 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 BldcDriver design in my own project?
The repository has no license, so all rights stay with dwanpo. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the BldcDriver 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.
