Simple Raspberry PI Serial Port and Breakout Board

Add a RS232 serial port and GPIO breakout to your Raspberry PI using this simple single-sided circuit board that you can build at home.

To keep the design simple and easy to lay out on a single sided board, only 5 GPIO pins were connected to a socket strip – this is fine for initial experimentation. The serial port allows the Raspberry PI to be connected to a PC without the need to connect a keyboard and screen to the Raspberry PI.
