2.3 FT232L Device
The FT232L device is connected to the USB connector and acts as an interface
between the PC and the JN5168 device. The FT232L will enumerate on the PC
as a virtual COM port connected directly to UART0 on the JN5168.
2.4 JN5168 Device
The JN5168 circuit is based around the standard JN-RD-6038 JN5168 reference
design; however it is built on a 2 layer board as the DIOs do not need to be
externally available.
