Re: Custom Circuit Design
All right. So I looked at the documentation for the gumstix robostix and the number of external interrupts that are connected to pins is to small. Thus, I have decided to use a MEGA AVR (don't know which one yet). This means we will have to build our own circuit board. Does anyone have suggestions for how to go about designing, building, or implementing a board? Should I go for perfboard or order a PCB per a design that I make? Is there a free CAD software I should use? What about outputs from the board: should I provide other connections than just the no-brained TTL/RS232? I really want to have a prototpe that might work with next year's control system.
Any suggestions/comments are very much appreciated! I so intend to document the prototyping project and make it nearly entirely open-source so other teams can learn to do this too... Last edited by manderson5192 : 29-02-2008 at 01:22. Reason: spelling and grammatical corrections |
