For anybody experiencing dropped connections on the Edimax WiFi Adapter
I found that the root of the problem was not the adapter, but Raspian attempting to save power by shutting off the WiFi adapter when it becomes idle. If you are experiencing dropped connections, open terminal and make a file 8192cu.conf in directory /etc/modprobe.d/ with the command:
sudo nano /etc/modprobe.d/8192cu.conf
Then add the following line to the file
options 8192cu rtw_power_mgnt=0 rtw_enusbss=0
You should be all set! No more dropped connections!

I have ordered a new board but I am also going to try to replace the following components on the old board’s M3 channel in the hopes that I can fix it.
Qty 2 - A09T N-Channel MOSFET
Qty 2 - A19T P-Channel MOSFET
I’ll also post some working code once I get the new one.
Updates to follow…
| | | WARNING! | | | RISK OF SHORT CIRCUIT!
I bought one of these boards and I placed in on top on my Arduino Uno and I failed to notice that the Uno’s USB header’s metal housing came in direct contact with the through-hole pins of the terminal block for motor 3 (M3). I powered on the board, a quick puff of smoke came out. I cut the power source, removed the board and quickly realized why the short-out happened. Consequently the MOSFET are blown out for M3. :(
I hope my mistake helps you avoid frustration.

Spark fun sells soldering irons and the parts to make a soldering robot so YOU don’t have to look this ridiculous!

“Why are you looking at me like I have two heads? I thought SparkFun didn’t have a rigid dress code. May I continue with the presentation?”
“…and after designing this air-tight heavily insulated suit I nominate myself to experience first hand SparkFun’s second High Altitude Balloon Project. We figure that if we have a manned balloon, the balloon should be able to find us in the event that we can’t find it.”
Lets give away something else for free. Perhaps we can learn form the internet traffic and try to better prepare our servers for Free Day.
No public wish lists :(
