Questions
How big is the Esp.seq PCB?
It measures 58.4 × 109.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp.seq use?
193 parts, built around the CP2102, ESP32-S2-WROVER-I(4M), TL072 and AMS1117-3.3. 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.seq KiCad files?
From the amonbenson/esp.seq repository on GitHub, at the commit this page was made from: the board is hardware/esp.seq/esp.seq.kicad_pcb and its schematic hardware/esp.seq/esp.seq.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp.seq design in my own project?
Its repository states no licence, so its author keeps all rights: ask amonbenson before reusing the design.
