Hi everyone!

I´m new to Primer2, I bought one in Future Electronics last week but when I open it to reinforce the GND path in U9 I´m notice that the hardware it´s different. The C23 tantalum cap C23 isn´t placed to left of U9 but upper to it and has another component solder over C23. It it´s placed where U10 are in the specs and in my board U10 it´s left to C23 and U9. The version printed near the SD conector it´s 1.2.

Any idea?

Hi,

The PCB has changed between version 1.0 and 1.1. Since this version, C23 is located upper U9, and the GND has been reinforced.
During the last fab, a transil has been added on C23, for overvoltage protection, in order to prevent U9 destruction by ESD.

THANKS!!!! That are GREAT news. Can I download the actualized schematics and place components from anywhere? THANKS AGAIN

You were right, the resources page was not up to date...
I changed the gerber and placement files to version 1.2.
