BMS-Master: common questions
What microcontroller does the BMS-Master use?
The BMS-Master is built around the STM32F303CCT6, from the STM32 family.
How big is the BMS-Master PCB?
The BMS-Master measures 135.1 × 159.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the BMS-Master?
218 components, from 78 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 BMS-Master design files?
From the UCDFS/Circuits 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 BMS-Master design in my own project?
The repository has no license, so all rights stay with UCDFS. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the BMS-Master 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.
