To use AVR UART engine you need external inverter in front of RX and TX pin.
Otherwise you can software serial routine to communicate the keyboard.
This converter uses software method, you doesn't need any inverter part.
This converter uses software method by default, so you don't need any inverter part. But
it can also be built with 'make HARDWARE_SERIAL=y' to enable hardware serial if there
is an inverter present. Good results have been obtained using a 74LS04 and hardware serial.
