unixbigot/mumbleA miniature battery-powered 2D plotter controller
Mumble is an open-source printed circuit board by unixbigot, from the unixbigot/mumble repository on GitHub. It is a 2-layer board of 100 × 30 mm with 67 parts on 60 nets, routed with 601 tracks and 93 vias.
It is built around the ESP32-WROOM-32, DRV8834PWP and TP4054. Its parts include 22 resistors, 16 capacitors, 6 connectors, 6 switches and 5 ICs. It belongs with the robots and motor control boards and the ESP32 boards of this library.
Mumble is a board for the ESP32 port of GRBL, targetted at low-voltage stepper motors. It was designed for the Minigraph CNC sticker plotter, but is intended to be usable for other CNC experiments.
It exposes all the GRBL pins, and has three DRV8834 low-votage motor drivers on-board.
Unlike the more popular A4988, the DRV8834 operates from motor voltage in the range 3v to 10.8v, making it suitable
for low-voltage miniature steppers.
The board also features a lithium battery charge controller.

Создать проект печатной платы в KiCad. Проект должен содержать:
It measures 100 × 30 mm and has 2 copper layers, 1.6 mm thick.
67 parts, built around the ESP32-WROOM-32, DRV8834PWP and TP4054. 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 unixbigot/mumble repository on GitHub, at the commit this page was made from: the board is mumble.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask unixbigot before reusing the design.
