Questions
How big is the LVGLDevKit PCB?
It measures 35 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LVGLDevKit use?
40 parts, built around the CH340C, ESP32-WROOM-32, AMS1117-3.3 and SIQ-02FVS3. 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 LVGLDevKit KiCad files?
From the jppang/ESP32_MicroPython_LVGL_ST7789 repository on GitHub, at the commit this page was made from: the board is hardware/LVGLDevKit.kicad_pcb and its schematic hardware/LVGLDevKit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LVGLDevKit design in my own project?
Its repository states no licence, so its author keeps all rights: ask jppang before reusing the design.
