Overview

First is an open-source printed circuit board by rhettg, from the rhettg/FirstMotorBoard repository on GitHub. It is a 2-layer board with 10 parts on 49 nets, routed with 176 tracks and 36 vias.

It is built around the ESP32-S3-WROOM-1-N8 and L293D. Its parts include 2 resistors, 2 ICs and 1 connector. It belongs with the robots and motor control boards and the ESP32 boards of this library.

Questions

What parts does the First use?

10 parts, built around the ESP32-S3-WROOM-1-N8 and L293D. 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 First KiCad files?

From the rhettg/FirstMotorBoard repository on GitHub, at the commit this page was made from: the board is First.kicad_pcb and its schematic First.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the First design in my own project?

Its repository states no licence, so its author keeps all rights: ask rhettg before reusing the design.
