BallBalncer: common questions

What microcontroller does the BallBalncer use?

The BallBalncer is built around the STM32G431K8Tx, from the STM32 family.

How big is the BallBalncer PCB?

The BallBalncer measures 64.5 × 77 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BallBalncer?

98 components, from 36 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 BallBalncer design files?

From the MarcelKleiner/BallBalncer 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 BallBalncer design in my own project?

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

Can I test firmware for the BallBalncer 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.
