Started: September 21 2013
Status: Active
Goal: experiment with Eagle and making pcb's and ending with an awesome thingy.
Who: Ardillo


Thanks to the guys of puscii. I found out that there is/was an event at Ordina Nieuwegein and thanks of that I found the open source project of Tim Becker.


Tim designed the AnyKey0x.de which is a small development board. As an enthousiast of small-and-capable-of-a-lot hardware I really wanted one, and with me a couple others. Since Tim made his project completely open source, I would like to thank Tim for sharing such an awesome project. All the kudo's (or base) belong to you.


The only change I made for now is just the text on the board, but it would be nice if we made some major changes to it. That depends a little on the enthusiasm we get from it. So at the moment it's just a fork of the original with no enhancements what so ever.



Before doing this I needed to refresh my skills with Eagle. I used a simple howto guide on the sparfun website.
Eagle: Schematics
Eagle: PCB Layout
In the end you'll have a fully (Sparkfun modified) Eagle setup and the knowledge to make a Serial to USB converter, because it's the training object of the tutorial.


Get the board printed by a company like smart-prototyping.com and search for the needed hardware. It is actually better to look for the parts first, but we'll see. Zarya from hackerspace Bitlair pointed me to some PCB fabhouses. I pasted their URL's in the reference. For this prototype I'm going to use smart-prototyping.com, but they need 10 gerber files instead of the normal 7. Which can be found on their website.

All Files: no offset, no mirror,no rotate, no upside down

.TXT (Drill & Holes)

Use Gerber_RS274X:
.GML (Outline)
.GTP (Solder Paste Top)
.GBP (Solder Paste Bottom)
.GTS (Solder Mask Top)
.GBS (Solder Mask Bottom)
.GTO (Silk Screen Top)
.GBO (Silk Screen Bottom)
.GTL (Top layer)
.GBL (Bottom Layer)

Because the normal CAM processor only generates 7 of 10 Gerber files, I made a special .cam file which can be downloaded here. This will generate the asked 10 Gerber files. No guarantee, I'll let you know when the boards arrive.

Check Gerber Files

You can check the files with a free viewer downloadable here. This tool is Windows only :( I ran it in an Win7 VM, works fine.


Printing PCB (10x) + shipping                    18.18€
Parts come...

Total                                            18.18€


AnyKey0x.de -- the one and only original
AnyKey0x.de Github -- all the files including sdk
Post @knutsel.org -- making cheap PCB's
MakePCB.com -- for making PCB's off course
iTead -- if <10, cheap one
Smart Prototyping -- cheapest one by far


EAGLE PCB Software -- Eagle PCB designer
viewplot -- Free viewer of gerber files (last check before sending it to fabhouse)
