Corrected PK2 Schematic

12/7/2014

0 Comments

 
A reader of this blog, Frans Stevens, pointed out that the schematic for my Build Your Own PICkit 2 schematic had an error. The USB connections to D+ and D- were backward. I quickly looked over the schematic and also the PCB layout because I've built many of these and they all worked. But I found out he was right, the schematic was wrong. Luckily the PCB was correct and that is why all my PK2 programmers work fine.

Pin 2 of the USB needs to connect to D- and pin 3 needs to connect to D+. I had them backwards in the schematic. So I immediately updated the schematic and uploaded to the Build Your Own PICkit 2 page. Its awesome to have such supportive readers with the willingness to share any errors they find. I want my information to be accurate but I'm human and do make mistakes. Thanks Frans.
