1.2 Before You Begin

The following warnings and cautions are noted for the safety of anyone using or working close to the TPSM843620EVM. Observe all safety precautions.

GUID-1B78A01B-7A0C-4E9D-9030-B06F1F8C87A9-low.pngWarningThe TPSM843620EVM can become hot during operation due to dissipation of power in some operating conditions. Avoid contact with the board. Follow all applicable safety procedures applicable to your laboratory.
WARNING:

The circuit module has signal traces, components, and component leads on the bottom of the board. This can result in exposed voltages, hot surfaces or sharp edges. Do not reach under the board during operation.

CAUTION:

Some power supplies can be damaged by application of external voltages. If using more than 1 power supply, check your equipment requirements and use blocking diodes or other isolation techniques, as needed, to prevent damage to your equipment.
