AM275x Evaluation Module User's Guide

Description

The AM275x evaluation module (EVM) is a
standalone test, development and evaluation platform
that lets developers evaluate AM275x functionality
and develop prototypes for a variety of applications.
The AM275x EVM is equipped with an AM275x
microcontroller along with additional components to
allow the user to make use of the various device
interfaces including the Ethernet
others to easily create prototypes. Onboard current
measurement capabilities are available to monitor
power consumption for power-conscious applications.
The supplied USB cable paired with embedded
emulation logic allows for emulation and debugging
using standard development tools such as Code
Composer Studio
(CCSTUDIO).

Features

Powered through two 5V, 3A USB Type-C
Multirail power supply designed for safety-relevant
