This project is a heavily modified fork of the open-source NovaSM3 quadruped, redesigned to serve as a research platform for embodied AI.
It measures 74 × 80 mm and has 2 copper layers, 1.6 mm thick.
20 parts, built around the ESP32-DEVKITC-32E, MLX90614ESF-BAA-000-TU, L7805CV and IRLB3034PBF. 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.
From the lordofchicken420/STEC_PCB repository on GitHub, at the commit this page was made from: the board is STEC_Design.kicad_pcb and its schematic STEC_Design.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask lordofchicken420 before reusing the design.
