This is the last design of tiny pinguino 4550 on a proto-board.
It was drawn with Inkscape:
You must cut the tracks marked with a red point.
I used this home made tool to do this:
Now you can sold components and wires. The 18F4550 must be mounted on a suport.
This version offers the same functionalities as the PCB version.
The booloader V2 must be used with this design.
Last upgrade 29/09/2009: Cutting points were modified, thanks to André.
The kicad file to build the board can be downloaded here.
An implant png file and a ps file of the PCB were added to the compressed file.
A tiny board was designed for 18F4550. This board, without external power supply will be used to test beta 7. It was designed with Kicad.

It’s a chance !! Pingino can be plugged on two breadboard giving more space to the test area…….
Pinguino 18F4550 is now defined. This is a tiny version USB powered. The run switch disappeared and 29 I/O are available. 8 analogic inputs.
Linux and windows version will be soon available and the KICAD PCB is in test.
Schematic upgraded. The last was buggy, led on pin 6 must be connected to Vcc because RA4 is an open collector output. Kicad board is OK. Thanks to walter for info.
Fabi from Madrid built his Pinguino on a proto-board. Very good idea !!
Maybe we can build a tiny Pinguino on a breadboard 🙂
I will try…………..
It seems that there is some problems to draw the PCB. An inkscape picture can be downloaded on hackinglab website.
This picture is scaled and can be used to build the PCB.
this is the link to the SVG file
This is the last version of Pinguino Hardware. It works with the modified version of PUF bootloader ( http://gforge.enseeiht.fr/projects/vasco/ )
