driver board has over-voltage protection in hardware and over-current shutdown through the MCU input.
Reverse voltage protection is available at 12-24VDC and EXT1-header external supply inputs. USB
interface headers are interfaced to the main MCU and EDBG device in the MCU board. Temperature
sensor, serial flash, XPRO interface header, and UID chip circuits are the other features included in the
driver board hardware. The figure below shows the main components and block diagram of driver board.
