bibishte/firmwares2programmes for microcontrollers ans schematic
Stepper is an open-source printed circuit board by bibishte, from the bibishte/firmwares repository on GitHub, published under the GPL-2.0 licence. It is a 2-layer board with 68 parts on 59 nets, routed with 641 tracks and 11 vias.
It is built around the MAX232N, DRV8825PWP and LTV-814. Its parts include 20 resistors, 17 capacitors, 12 ICs, 9 connectors and 2 diodes. It belongs with the robots and motor control boards and the AVR (ATmega, ATtiny) boards of this library.
This is a stepper motor controller. Based on DRV8825 by Texas Instruments. The programme is made with Netbeans v7.2 and the schematic with KiCAD v2.8.12.
This is my first project. It has two elements. The first one is the schematic and the PCB under CC license and firmware under GPL v2. It is used for controlling stepper motor up to 2.5Amps via serial interface RS232/RS485 for home or ingustrial automation or parallel galvanic opto isolated interface compatible with RepRap printers, Milling machines Mach3, LinuxCNC.
The PCB and schematic is under CC license.

68 parts, built around the MAX232N, DRV8825PWP and LTV-814. 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 bibishte/firmwares repository on GitHub, at the commit this page was made from: the board is stepper_schematic/stepper.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
