Problems with the Voltage Regulation Module VRM

Everyone,

I finally had a chance to finish up the report. Take a look at it and let me know if you guys find any issues with it! LINK

TL;DR: The module did not perform well in any of the three load tests. There are high levels of noise present on the regulator's output and output ripple is also above 500 mV for most tests. I also make the conclusion that radio performance may be affected by the module's poor performance.

I wish the rules allowed a bit more flexibility with regards to power regulation. Maybe something to consider for next year?

If I can get my hands on some additional test hardware, I'm going to try and perform tests using a D-Link radio. Look for an update sometime this weekend.
