Questions
How big is the ESP32 SLAM PCB DESIGN PCB?
It measures 100.8 × 65 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ESP32 SLAM PCB DESIGN use?
60 parts, built around the CH340C, ESP32-WROOM-32, LM2596S-5.0 and AMS1117. 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 SLAM PCB DESIGN KiCad files?
From the zaidh-mech/PROJECTS repository on GitHub, at the commit this page was made from: the board is TOF_SLAM/Robot_chassis/PCB_Design/ESP32_SLAM_PCB_DESIGN/ESP32_SLAM_PCB_DESIGN.kicad_pcb and its schematic TOF_SLAM/Robot_chassis/PCB_Design/ESP32_SLAM_PCB_DESIGN/ESP32_SLAM_PCB_DESIGN.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32 SLAM PCB DESIGN design in my own project?
Its repository states no licence, so its author keeps all rights: ask zaidh-mech before reusing the design.
