Questions
How big is the ESPCARproject PCB?
It measures 78 × 92 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESPCARproject use?
92 parts, built around the CH340C, ESP32-WROOM-32, AMS1117CD-3.3 and DW01A. 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 ESPCARproject KiCad files?
From the Sumya99/RobotCarPCB repository on GitHub, at the commit this page was made from: the board is ESPCARproject.kicad_pcb and its schematic Conn_schematics.kicad_sch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESPCARproject design in my own project?
Its repository states no licence, so its author keeps all rights: ask Sumya99 before reusing the design.
