CAUTION: This EVM contains components that can potentially be damaged by electrostatic discharge. Always transport and store the EVM in its supplied ESD bag when not in use. Handle using an antistatic wristband. Operate on an antistatic work surface. For more information on proper handling, refer to the Electrostatic Discharge (ESD) application note.
WARNING: By default, the I2C data and clock lines are pulled up internally to 3.3 V. If internal pullup resistors are not used and external ones are used instead, please make sure to pull up to 3.3 V only. Operation from 5 V is not specified and may permanently damage this USB Interface Adapter EVM.

The information in the caution and warning is provided for the user's protection. Please read each caution and warning carefully.
