LeapFrog Pollux Platform: Hardwire Serial Connection

The serial console (115200 8N1) comes out to the cartridge connector.
 * Counting from the right
 * tx comes out on pin 12
 * rx on pin 11.

The UART is using +3.3V TTL level which means you will need a RS232_Level_Shifter or use one of the following usb->rs232 breakout boards:


 * FT232R from DLPDESIGN
 * FT232R from Sparkfun
 * CP2102 from Sparkfun

 * Green UART-TX
 * Grey UART-RX
 * Black GROUND
 * Red +3.3V

The +3.3V isn't needed for all Uart connections, however some of the USB->RS-232 breakout boards may require a +3.3V reference voltage.
