Introduction
   The UART Block provides a level shifted interface to the console port or second UART port. This is a great solution when USB is not an option. This allows the Edison module to be interfaced with legacy hardware by providing a protected signal interface. Using a RS232 Shifter, it is possible to connect an Edison to RS232 devices commonly found in older automation equipment and instrumentation. The UART Block paired with a 5V Compatible FTDI device, such as our FTDI Basic Breakout, will power an Edison Stack.
