 +==== Opening the case ====
 +**Note:** This will void your warranty!

 +To remove the cover, remove the 4 feet and use a torx T-10 with hole or 2.5mm flathead to remove the screws.

 +
 +==== Serial ====
 +-> [[doc:hardware:port.serial]] general information about the serial port, serial port cable, etc.
 +
 +There is an unfilled five-pin header labeled JP1 which is a 3.3V TTL [[doc:hardware:port.serial|serial port]]. Experimentation with an oscilloscope indicates that it runs at 115200 8N1, but I'm waiting on the arrival of my serial adapter to verify. I believe this is the correct pinout, but I'm not certain about RxD and NC.
