Made this in order to test the samples I (again) got from microchip… (coolest guys in the world.. If I ever make something sellable in huge numbers with a microcontroller, it will surely be a PIC :) .

I include the brd file of eagle so you can make it yourself (it is tested that it works). If you want you can print the bottom layer on a laser printer and then iron the paper on the back side of the board so you can have the pinouts printed on the top side..

files as always here

A (failed) experiment: I got 18F6621 samples from microchip.com (I LOVE these guys!!) and they are packaged in a TQFP64 package (a very dificult to use package if you are not a machine) so I decided to make a breakout box. Get those pins in pin header format so I can stick whatever I want [...]]]>

A (failed) experiment: I got 18F6621 samples from microchip.com (I LOVE these guys!!) and they are packaged in a TQFP64 package (a very dificult to use package if you are not a machine) so I decided to make a breakout box. Get those pins in pin header format so I can stick whatever I want to them. But I failed miserably. The design was haunted by the 8mil distance between the legs. It proved more (less) than my etching method could handle so I had heavy crosstalk between the leads.

And the soldering was no easy job too!!!!!

But if you feel adventurous, there are brd files you can use to despair on your own :)
