Battery board v2: common questions
What microcontroller does the Battery board v2 use?
The Battery board v2 is built around the STM32F030F4P6, from the STM32 family.
How big is the Battery board v2?
The Battery board v2 measures 90.2 × 96 mm, has 4 copper layers and is 4.69 mm thick.
How many components are on the Battery board v2?
119 components, from 68 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 Battery board v2 design files?
From the queens-satellite-team/pcbs 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 Battery board v2 design in my own project?
The repository has no license, so all rights stay with queens-satellite-team. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Battery board v2 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.
