BMS Master V7: common questions

What microcontroller does the BMS Master V7 use?

The BMS Master V7 is built around the STM32f4_board_v3-1, from the STM32 family.

How big is the BMS Master V7 PCB?

The BMS Master V7 measures 77 × 58.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the BMS Master V7?

116 components, from 55 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 V7 design files?

From the TERA-TU-Graz/BatteryManagement_2017 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the BMS Master V7 design in my own project?

It is published under SHL-2.1, which limits how it may be reused; read the license before building on it.

Can I test firmware for the BMS Master V7 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.
