AD9833 Breakout Short I recently bought a breakout board for an AD9833 waveform generator, but discovered pretty quickly that VDD and GND were shorted out. Assuming that there must have been some manufacturing defect, I checked the board over but could see nothing unusual. I got hold of a replacement module and exactly the same issue presented itself. I simply can't figure out what the problem is. Does anyone know of an issue with these boards, or am I just missing something blindingly obvious? Any thoughts much appreciated.

Thanks for the responses. I discovered the short initially by connecting power from an Arduino and seeing the Uno's LED turn off. I then tested with a DMM and confirmed the short. Thinking that I could have damaged the module, I got another one and this time tested with a DMM first, with the same result. The resistance reads as 0.4 ohms (the resistance of my probes) so I am convinced that it is a dead short. I've checked the soldering carefully and can see no bridges etc. This was admittedly a cheap product from eBay, but I'm surprised that two in a row had the same issue. I could just buy a different version, but this type seemed the most convenient for prototyping.
Pictures as requested:
I was going to post this as a comment, as it is by no means a definitive answer, but I wanted to include the schematic to help the OP understand what may be happening. When the OP provides further information, I will edit/delete as appropriate.



Without additional information, it is difficult to answer your question:


As Jot asks, how did you determine that you have a short? 


Did you test for continuity between VCC and GND, using a DMM? 
Or did you encounter the short by connecting to a power supply and blowing a fuse?

If you did perform a check of the resistance between VCC and GND, using a DMM, what was the value that you obtained?
Is it possible that what you think is a short, could be simply a temporal charging of the capacitors by the DMM (if that is what you used to determine the short)?
