Hello,
I bought an EZ-Robot kit at Maker Faire last weekend but have been having all manner of trouble getting it to work reliably (difficulty making & maintaining Bluetooth connections, servos chattering under no load/heatsinks getting hot, random board resets & brownouts). I finally figured I might have a faulty board when the HC-SR04 sensor I wired up started smoking. Upon testing, I found that I was getting the full supply voltage (i.e., whatever I was supplying to the power plug) at all the '5v' outs from the board. The 3.3v pin is fine. It makes no difference if I use a 9v battery pack or 12v external PSU, whatever I put in, I get out from the 5v lines.
Is there anything else I should look for before I open an RMA ticket?
Thanks!

B-tooth connection uninstall and re-install the driver, if possible use external driver and not the built in Microsoft driver.
What operating system are you running?
If I am not mistaking EZ-B board can only put out 5V and 3.3V ( hint the 5 Amp fuse, will blow if large current or large voltage running across the boardboard
as @rich stated above check your board and all wires connection for any miniscule sign of shortage.
Connection issues Are 90 percent of the time due to using unsupported aftermarket Bluetooth stack. You can try uninstalling the Bluetooth then unplugging it and plug it back in. Win 7 will install the default drivers by itself.
Thanks,

Looks like there are a few in the office so chances are someone will be on shortly - although don't quote me on that
