Freeduino PCB 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. Additionally, while Arduino is a protected trademark, Freeduino comes with a free and unrestricted license to use the Freeduino name, available for any use.

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 the these; see below. The idea here is to make available the Eagle files you would need to make your own Freeduino variant board.

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.


Original Freeduino Files:

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



Protoype run of version 1.16


0603 surface-mount version


1206 surface-mount version


Through-hole component version (easiest to assemble!)

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.

(FORK from schematic only to schematic & 0603/ 1206 board routes.
