Questions
How big is the Heimdall PCB?
It measures 21 × 37.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Heimdall use?
18 parts, built around the ESP-01, TLP222AF and TPS62177DQC. 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 Heimdall KiCad files?
From the HarkonenBade/heimdall repository on GitHub, at the commit this page was made from: the board is board/heimdall.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Heimdall design in my own project?
Its repository states no licence, so its author keeps all rights: ask HarkonenBade before reusing the design.
