Questions
How big is the Spider Robot PCB?
It measures 99.9 × 99.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Spider Robot use?
62 parts, built around the ESP32-DEVKITC-VE, XL4015E1, PCA9685PW and LM2596S-5.0. 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 Spider Robot KiCad files?
From the duvohuu/Spider_Robot repository on GitHub, at the commit this page was made from: the board is hardware/PCB.kicad_pcb and its schematic hardware/PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Spider Robot design in my own project?
Its repository states no licence, so its author keeps all rights: ask duvohuu before reusing the design.
