Old-BMS-dacus: common questions

What microcontroller does the Old-BMS-dacus use?

The Old-BMS-dacus is built around the STM32F373-48, from the STM32 family.

How big is the Old-BMS-dacus PCB?

The Old-BMS-dacus measures 120.6 × 78 mm and is 1.6002 mm thick.

How many components are on the Old-BMS-dacus?

177 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the Old-BMS-dacus design files?

From the kitspace/component_tester repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Old-BMS-dacus design in my own project?

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

Can I test firmware for the Old-BMS-dacus 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.
