How to build your own USB to UART serial converter using cheap FT232 with voltage level shifting

Meet Bordy the Converter. A custom USB to UART serial converter.

The board includes 500mA fuse protection, EMI filtering, power LED indicator, RX and TX LED indicators, and a voltage level shifter that makes it compatible with 3.3V and 5V boards. With Bordy you don't need to check the jumper if it outputs 5 or 3.3V so you don't risk burning your microcontroller. It just works with both voltages. And all this for just 5 bucks.
Eagle schematic and board layout is available for download down below.
