Access to CPU pins for experimenting...

James Zdunic
 
Edited

The primary reason I am building the ubitx & JackAl is to end up with an embedded development platform that I can do mad scientist activities on.? My approach to selecting and mounting the CPU related headers makes for easy access to the CPU pins for experimenting using receptacle connectors.? This includes the otherwise hidden internal rows of CPU pins.? I also populated all points on the Audio board with with receptacle connectors.? The soldering process sequence I used prevented me from soldering myself in a corner and ending up with tight spots to solder within.? Attached are instructions for those who may be interested in doing the same thing.

EDIT:? Step 4 of the attachment calls for a 6 point receptacle which should read 10 point receptacle.

Jim:

Thanks for the document file. I'm sure there will be other like you who want to experiment beyond what we've provided. Would it be okay if we posted your file so others can use it?
