Questions
How big is the Esp flasher PCB?
It measures 23.5 × 30.5 mm and has 2 copper layers, 0.8 mm thick.
What parts does the Esp flasher use?
49 parts, built around the CH340C, ME6211C33M5G-N, USBLC6-2SC6 and DTC114YUA. 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 Esp flasher KiCad files?
From the makerspacelt/esp-flasher repository on GitHub, at the commit this page was made from: the board is project/project.kicad_pcb and its schematic project/project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp flasher design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
