After some probing, I found the serial console (115200 8N1) comes out to the cartridge connector. Counting from the right, tx comes out on pin 12 and rx on pin 11.  The voltage level goes between 0 and 3.3 volts.  Hooking into a TTL to RS-232 converter, left over from another project, I can get to the console.

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:
