TE0722-02 vs TE0722-01
« on: November 11, 2017, 10:33:35 AM »
Hi!

Could you explain what is the difference between REV1 and REV2.
I mean what kind of SCH/PCB bugs you solved in REV2.

I know that REV1 was open source project (hosted on github).
Is it possible to get REV2 sources (AD project) ? Will it be uploaded on github ?

Thanks a lot!

Hi,

changes:
  • replaced R7 on 10K, R15 on 19K1
  • added series resistors(33 Ohm) to RGB led (R29 .. R31)
  • added pull-up resistors (10K) to SD-card  (R23 .. R28 ) 
  • added series resistors 33 Ohm (R32, R21)
  • Zynq VREFP_0/VREFN_0 connect to AGND
  • Add ferrite to AVCC   (L1, L2)
  • Add testpoint for 3.3V, GND
  • Rebuilded all poligons
  • Changed voltage on resistor R7 (input sense supervisor) 3.3V -> 1.0V
Compare to Schematics:

We will add a REV02 Altium project to our download area:

I think this should be available in 2 or 3 hours.
