Questions
How big is the ESPRocks PCB?
It measures 35.6 × 85.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESPRocks use?
83 parts, built around the ESP32-WROOM-32E, CH340G, SPX3819M5-L-3-3 and SS34. 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 ESPRocks KiCad files?
From the ffich/ESPRocks_KURT repository on GitHub, at the commit this page was made from: the board is 10_PCB/ESPRocks_Kurt/ESPRocks.kicad_pcb and its schematic 10_PCB/ESPRocks_Adapters/ESPRocks.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESPRocks design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
