Hi Community, I am currently trying to build a FEZ domino board from scratch. I took the board Eagle schematics and had 4PCB.com create me a PCB. I then purchased the components form NEWARK.COM that were on the Excel file.
Unfortunately I am not able to get my computer to recognize the attached board when I plug it into the USB connector. I have checked to make sure that all of the VDD’s are connected to the pins on the board. I have checked my voltage regulators, both the 5v and the 3.3 v regulators to make sure they are outputting the correct voltages.
I have a FEZ board that I purchased complete and I have been comparing some of the voltage values to my board and have found that the D+ and D- of the mini USB controller are at ~.1mV this is very wrong because the Voltage on the board from TinyCRL has these both at ~2.5V.
I’ve tried everything I can think of to fix this problem
