Power Supply Input Polarity and Maximum Voltage
Always ensure that the polarity and voltage of the external power
connected to V power input connector J1, J2, and/or V
CC
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.
