3.1.3 Extra Power Supplies

The SAM9X75 Curiosity Pro supports many add-on boards with various power supply constraints. To satisfy all power requirements of large loads from add-on slots, additional power supplies are implemented on the main board using the MIC23450, providing an additional 3.3V rail (VDD_3V3_B), 2.5V rail (VDD_2V5_B) and 1.0V rail (VDD_1V0_B).
