Power Tree - Arduino GIGA R1 WiFi Product Reference Manual

12 Power Tree

Power can either be supplied via the VIN pins, or the 5V of the USB connectors (J2, J12). If power is supplied via VIN,
the MP2269GD-Z (U7) buck converter steps the voltage down to 5V. The 5V power rail is then stepped down to 3.3V
by the MP2322GQH (U6) buck converter. The logic level of components on the Arduino GIGA R1 WiFi is 3.3V.
