UART setting jumpers

WIFI module and XBee module communicate with atmega32u4 via UART，as they cannot use the same serial port for communication, there are two sets of UART setting jumpers to configure UART communication as below： IM130626001_2.jpg

D0 and D1 are hardware UART serial ports for Arduino, and D11 and D12 are common IO interfaces. There are two ways to set UART communication.
