Questions
How big is the Hackthon PCB PCB?
It measures 137 × 54.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackthon PCB use?
10 parts, built around the ESP32-C3-DEVKITM-1 and DHT11. 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 Hackthon PCB KiCad files?
From the vruga/esp_medmonitor repository on GitHub, at the commit this page was made from: the board is Hackthon_PCB/Hackthon_PCB.kicad_pcb and its schematic Hackthon_PCB/Hackthon_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackthon PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask vruga before reusing the design.
