Questions

How big is the Bat PCB?

It measures 76.2 × 50.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Bat use?

5 parts, built around the BQ24073RGTR. 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 Bat KiCad files?

From the STM32World/hardware repository on GitHub, at the commit this page was made from: the board is bat/bat.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Bat design in my own project?

Its repository states no licence, so its author keeps all rights: ask STM32World before reusing the design.
