EPDiy Hardware

Design files for EPDiy controllers, controller variants, display adaptors, and other related hardware.
See vroland.github.io/epdiy-hardware/ for available hardware.

What is EPDiy?

Please refer to the main project repository for more information.

Cloning

Make sure to clone recursively, to get hardware library submodules:

git clone git@github.com:vroland/epdiy-hardware.git --recursive
# or with http
git clone https://github.com/vroland/epdiy-hardware.git --recursive

Contributing Hardware

Contributions in the form of adapter boards, utilities or epdiy variants are always welcome! Please submit a PR and make sure your KiCAD project is in the right format, so our automation can build the manufacturing files and overview page:

• For every board, the KiCAD project should be given a unique name, and have the same name as the containing folder. Example: epdiy-v7/epdiy-v7.{kicad_pro,kicad_pcb,kicad_sch}. An existing KiCAD project can be renamed by selecting File -> Save As in the main KiCAD window and saving it to a folder with the new name.
• Unless you explicitly specify otherwise, your contribution will be licensed under the Creative Commons Attribution-ShareAlike 4.0 International License. Feel free to mention in the README in your project folder how you want to be attributed. Please indicate in the PR if you intend to use a different license.
• Each board needs a README.md in it's project folder, which will also appear as description in the presentation page. Refer to epdiy-v7/README.md for an example.
• If it's a helper or an adapter board, place it in the appropriate helpers or adapters folder.
• Delete the manufacturing files and keep only the sources. Since we generate those automatically, having potentially outdated ones in the repo will be confusing.
• Add your board to the BOARDS list in the root Makefile. This enables the continuous integration to build the manufacturing files for your board.

Available Hardware

The full list of available hardware is available at vroland.github.io/epdiy-hardware/. For each board, we provide:

• Gerber files
• Bill of Materials (BoM)
• Pick & Place Positioning file
• PDF Schematic
• 3D model of the board for use in CAD

Alternative Parts

Some components can be swapped for more cheaper or more available parts, without impacting the functionality of the epdiy controlling board. If you find other alternatives that may be useful to others, please submit a pull request!

Part name	Replacement Name	Default LCSC ID	Replacement ID	Comments
TPS651851RSLR	TPS65185RSLR	C139292	C702311	Only if your panel size <= 9"
XF2M-3315-1A**	FH12-33S-0.5SH(55)	C231420	C597986	Omron connector is better quality than Hirose replacement
MBR0540T1G	B5819W SL	C8598	C21353	Much cheaper diode when ordering from LCSC

** IMPORTANT: XF2M-3315-1A replacement C597986 uses a slightly different footprint. It has to be updated in KiCad PCB before sending fabrication files to production.
