The Mother Board has been designed with ease of use in mind and has been segmented into functional
blocks as shown in
Detailed silkscreen legend has been used throughout the board to identify
all switches, jumpers and user connectors.

Power Supply Configuration
The EVB requires an external power supply voltage of 12 V DC, minimum 1 A. This allows the EVB
to be easily used in a vehicle if required. The single input voltage is regulated on-board using three
switching regulators to provide the necessary EVB and MCU operating voltages of 5.0 V, 3.3 V, 1.25 V
and one 5 V linear regulator for the ADC supplies and references.
For flexibility there are two different power supply input connectors on the motherboard as detailed
below. There is also a power supply option on the daughter card to use the daughter card in standalone
mode. Please refer to
Section 4.1.2, 4.1.3 “Daughter Card Standalone Power Input -External &
Daughter Card Standalone Power Input –Power SBC”
for details on the daughter card power input.
