Questions
How big is the BLDriver PCB?
It measures 42.4 × 57 mm and has 4 copper layers, 1.6 mm thick.
What parts does the BLDriver use?
38 parts, built around the STM32G071CBT6 and CC0603KRX7R7BB105. 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 BLDriver KiCad files?
From the jviereck/SemiRoute repository on GitHub, at the commit this page was made from: the board is BLDriver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BLDriver design in my own project?
Its repository states no licence, so its author keeps all rights: ask jviereck before reusing the design.
