Questions
How big is the Esp32-dalitester PCB?
It measures 90 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32-dalitester use?
84 parts, built around the CH340C, ESP32-WROOM-32D, MT3608 and PSSI2021SAY. 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-dalitester KiCad files?
From the lukasprojects/esp32-dalitester repository on GitHub, at the commit this page was made from: the board is KiCAD/ESP32_DALITester/ESP32_DALITester.kicad_pcb and its schematic KiCAD/ESP32_DALITester/ESP32_DALITester.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32-dalitester design in my own project?
Its repository states no licence, so its author keeps all rights: ask lukasprojects before reusing the design.
