Hardware is based off an open source project called Speeduino by Josh Stewart.

"3D Printer Shield" is a board to run 3D printer using ODROID single board computer, technically this board is designed to control the motor driver modules with TMC2209 (UART) or TMC2130 (SPI) through the on-board GPIO…
Klipper is an open-source printed circuit board by tobetter, from the tobetter/3DPrinterShield repository on GitHub, published under the GPL-3.0 licence. It is a 4-layer board of 71.9 × 91 mm with 111 parts on 130 nets, routed with 1,316 tracks and 151 vias.
It is built around the 100UF/35V, IRFR024N and 10UF 10V, with the IRLR7843TRPBF and S1D among its other parts. Its parts include 41 resistors, 32 connectors, 16 capacitors, 6 diodes and 5 ICs. It belongs with the robots and motor control boards of this library.
"3D Printer Shield" is a board to run 3D printer using ODROID single board computer, technically this board is designed to control the motor driver modules with TMC2209 (UART) or TMC2130 (SPI) through the on-board GPIO headers without an additional processessor.

Originally this project is started to use RAMPS 1.6, but has changed to design a new board since board connection is quite different.
The board has been tested with Ender-3 and runs by Klipper.
Then later, I've built an OS image to run Klipper on ODROID-C4 and the image can be downloaded from the link

It measures 71.9 × 91 mm and has 4 copper layers, 1.6 mm thick.
111 parts, built around the 100UF/35V, IRFR024N, 10UF 10V and IRLR7843TRPBF. 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 tobetter/3DPrinterShield repository on GitHub, at the commit this page was made from: the board is Klipper.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).
