Precautions

2-2

Quick Start

2.1

Precautions

Power Supply Input Polarity and Maximum Voltage

Always ensure that the polarity and voltage of the external power
connected to V

CC

power input connector J1, J2, and/or V

DD

power

input connector J6 are correct. Overvoltage or reverse-polarity
power applied to these terminals can open onboard soldered-in
fuses and cause other damage to the platform, installed evaluation
modules, and/or the power source.

Inserting or Removing EVM Boards

Do not insert or remove EVM boards with power applied—damage
to the EVM board, the platform, or both may result.
