Questions
How big is the ESPHMI PCB?
It measures 17.8 × 53.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ESPHMI use?
39 parts, built around the CP2104EK, ESP32-S2, W25Q128JVSIQ and L8050QLT1G. 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 ESPHMI KiCad files?
From the maglash64/ESP32-S2-DEV repository on GitHub, at the commit this page was made from: the board is ESPHMI.kicad_pcb and its schematic ESPHMI.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESPHMI design in my own project?
Its repository states no licence, so its author keeps all rights: ask maglash64 before reusing the design.
