3.3 Power-On/Off Procedures

Power to the EVM is provided through an external AC/DC converter providing 12 Volt, 5 A (max) DC voltage to the J6 power jack.

See the Power Supply list in Key Features for TI's recommendation on an appropriate AC/DC power converter for the user's EVM revision.

CAUTION: To avoid high inrush currents, and prevent possible damage to the AM64x/AM243x EVM components, the following EVM power on and power off procedures must be utilized.
