Questions

How big is the Balance bot PCB?

It measures 56.2 × 69.4 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Balance bot use?

21 parts, built around the MSP430G2553IN20 and LM1084IT-3.3/NOPB. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Balance bot KiCad files?

From the apnelsonl/balance_bot_layout repository on GitHub, at the commit this page was made from: the board is balance_bot.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Balance bot design in my own project?

Its repository states no licence, so its author keeps all rights: ask apnelsonl before reusing the design.
