Questions
How big is the ESP32-WROOM tryout PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32-WROOM tryout use?
64 parts, built around the CH340C 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 ESP32-WROOM tryout KiCad files?
From the koson/esp32-playlist repository on GitHub, at the commit this page was made from: the board is ESP32-WROOM_tryout/hardware/ESP32-WROOM_tryout.kicad_pcb and its schematic hardware/ESP32-PicoDK/ESP32-PicoDK.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32-WROOM tryout design in my own project?
Its repository states no licence, so its author keeps all rights: ask koson before reusing the design.
