Description
The Skymega is an electronic board for programming printbots. It is open source hardware, designed with the open source tools Kicad (we have named this kind of hardware as open source squared). It is based on the ATmega microcontrollers, so it is Arduino compatible.
This board has been specifically designed for building modular robots or mini mobile robots. Currently we are using it at Universidad Carlos III de Madrid for the following printbots:
* Miniskybot: thingiverse.com/thing:7989
* Repy1 1.1 modules: thingiverse.com/thing:13442
* F-track: thingiverse.com/thing:13298
* Orugator: thingiverse.com/thing:8559
Features:
* Small in size
* Easy to build by the students
* ON/OFF switch
* Arduino compatible
* Connection up to 8 servos
* I2C bus
* 1 Test button
* 2 Test led
Authors
* Juan Gonzalez-Gomez (Obijuan)
* Andrés Prieto-Moreno
* Itziar Lima
* Ricardo Gomez

Instructions
You can manufacture the board with the provided Gerber files, or you can edit the schematic and PCB using the Kicad tool.
For the bill of materials please have a look at the skymega-BOM-en.pdf file.
The software is written and uploaded to the board using the Arduino environmnet. It is necessary to connect the Skymega to the PC by means of a modified FTDI cable (see the attached images for detailed instruccions)
Enjoy building and programming open source printbots!!!

beautiful, and thanks for sharing. But why modifying the ftdi cable? they are expensive.. maybe is better to make an adaptor..
Thanks! I am glad you like it :-) If you already have an FTDI cable with the standard 6 pin header, the solution you are proposing is much better: make an adaptor. What I am doing is just re-arranging the pins and inserting them into a 4 pin header. This operation is non-destructive. Just removing the pins from one header and inserting into another.
It also possible to buy a cheaper FTDI cable without any header, just plain wires and make the connector to the skymega
