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:

- 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.
