Hardware layout and configuration

The AT32-Comm-EV board is connected to the AT-START board through Arduino
this way, the EV board is able to access the CAN, USART, I
on AT-START board. This document uses AT-START-F403A board as an example to demonstrate
various functions.
In addition to the embedded AT32 MCU, the AT-START board offers standard Arduino
extension connectors to be connected to the AT32-Comm-EV board.
JP1 and JP2 are used to configure whether to turn on 120 Ω termination resistors of the CAN and
RS-485 transceivers, respectively. They are ON by default. The users are allowed to adjust the
resistors according to their needs.
