Functional Blocks Description
2.13 Dual Cameras
The two camera interfaces from the AM437x processor are terminated on the 12×2 headers, J2 and J3.
The custom-made camera module from TI with part number 4P0041 interfaces with the header J3. This
camera module is a separate camera board that attaches at a right angle so that the camera can face
horizontally when the GP EVM is lying on a test bench. The OmniVision OV2659 SOC-based 2-MP
camera module from SunnyOptics with part number P212A interfaces with the header J2. The OV2659
delivers a high-definition video and excellent low-light sensitivity for cost-sensitive applications.
2.14 Audio
The headphone output and line input signals from the two 3.5-mm SJ3524 jacks are connected to the
audio codec with part number TLV320AIC3106. These signals connect through the McASP1 and I2C
interfaces of the AM437x.

Power Supplies
This section describes how the power supplies required for the design are generated.
3.1
Power Source
AM437x GP EVM uses an external AC for a 5-V-DC (rated 2.5 A minimum) power adapter. The slide
switch SW2 is used to switch the main power to the board on and off. The main power is off when the
power switch is in the position away from the power supply jack. The main power is on when the power
switch is in the position closest to the power supply jack.
3.2
Power Sequencing
The power sequencing requirements of the AM437X processor (see the
AM437x data sheet
) are handled
automatically by the TPS65218 PMIC.
