cukier/EspCncProjeto de placa em KiCad (v9) para a interface entre um modulo ESP32 e a eletronica da CNC 3035: drivers de motor de passo (ex. A4988/DRV8825/TMC2208), fins-de-curso, controle de spindle/laser e alimentacao.
Body is an open-source printed circuit board by cukier, from the cukier/EspCnc repository on GitHub, published under the MIT licence. It is a 2-layer board of 77 × 70 mm with 67 parts on 52 nets, routed with 148 tracks and 0 vias.
It is built around the BC337, A4988 and IRF540N, with the SS34 among its other parts. Its parts include 28 resistors, 11 capacitors, 7 connectors, 6 diodes and 5 transistors.

ieb/autopilot
An ML Autopilot designed and written almost entirely by Google AntiGravity.
It measures 77 × 70 mm and has 2 copper layers, 1.6 mm thick.
67 parts, built around the BC337, A4988, IRF540N and SS34. 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 cukier/EspCnc repository on GitHub, at the commit this page was made from: the board is hardware/Body/Body.kicad_pcb and its schematic hardware/Body/Body.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
