BMS: common questions

How big is the BMS PCB?

The BMS measures 29.7 × 23.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BMS?

52 components, from 10 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 design files?

From the narimonjonmurodov/PCB-design 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 design in my own project?

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