Freeduino PCB Design Files

Freeduino is a collaborative open-source project to replicate and publish Arduino-compatible hardware files. The Freeduino Eagle SCH, BRD and Gerber production files allow users to create boards that are 100% functionally, electrically and physically compatible with Arduino hardware.

While Arduino is a protected trademark, Freeduino comes with a free and unrestricted license to use the Freeduino name, available for any use. This means you can do whatever you want with these files. The idea here is to make available the Eagle files you would need to make your own Freeduino variant board.

Freeduino currently consists of a Diecimilia-equivalent schematic and 0603, 0805, 1206 and through-hole routed board files. In addidtion, we have begun posting files derived from by others from the first Freeduino files (yes, Arduino>Freeduino>others!).


Freeduino is directly derived from the Creative-Commons 2.5 licensed Arduino reference design. See the schematic file for attribuition information. Freeduino is licensed for any use ( hobbyist, commercial, non-profit, etc.) under Creative Commons 2.5. The Freeduino name is not registered, but we encourage you to use it in any case.

CC2.5 requires you to maintain attribution to the people before you on the schematic and board files. You dont need to give attribution on the physical proucts that you might make with these files, as copyright in general, and CC2.5 in particular, do not apply to physical objects.


Original Freeduino Files:

Freeduino 0603 SMT prototype. The PCB designed was graciously designed by Westfw.


  • Through-hole component version .sch, and .brd files: in zipped Eagle format. This is actually a modification of the Arduino 2.1 USB design, made to be Diecimilia compatible and branded with the Freeduino name. Available as a kit with instructions. Posted September 15th, 2007
  • How to buy
  • Assembly Instructions

(We Forked things here, from schematic only to schematic & 0603/ 1206 board routes.)

  • Freeduino .sch and .brd files: v 1.13 in zipped Eagle format. Fixed fuse-ground short. September 4th, 2007.
  • Freeduino .sch and .brd files: v 1.12 in zipped Eagle format. Now includes board file with mostly SMT 0603 parts.Posted September 4th, 2007.
  • Freeduino Schematic: v 1.11 in zipped Eagle format. Fixed RX/TX leds.Posted August 30, 2007.
  • Freeduino Schematic version 1.1: this is the schematic only, in zipped Eagle format.
