Power Supply Configuration
The EVB requires an external power supply voltage of 12V DC, minimum 1.5A. 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 5.0V, 3.3V and
1.25V, and one 5V 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 for details on the daughter card power input.
