Encoder is an open-source printed circuit board by MakerMylo, from the MakerMylo/Embroiderino repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board with 11 parts on 5 nets, routed with 51 tracks and 0 vias.
Its parts include 3 resistors, 2 capacitors, 2 transistors, 1 diode and 1 connector.
Embroiderino is a test project which aims at providing all needed to turn an ordinary sewing machine into digital embroidery machine or at least to reuse any other embroidery machine with mainboard failure. Most of the mechanical parts are intended to be made on 3D printer.
As an electronics, arduio based 3D printer board is tested, with additional encoders connected to it. This will do job for now too. As a firmware teathimble is in development. For hoop positioning this plotter is adopted. All mechanics parts and sewing machine itself are mounted to chipboard.
Client application is written in python3 and TK, it can open CSV's created by Embroidermodder2.
Note that this is early stage development. Machine, main DC motor speed controller is a next milestone. All the code is licensed under GPL v3.

11 parts. 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 MakerMylo/Embroiderino repository on GitHub, at the commit this page was made from: the board is electronics/encoder/encoder.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
