•
Quick Start Guide
3.2 Assumptions
Familiarity with the I
2
C bus is helpful but not required.
3.3 Static handling requirements
CAUTION
This device is sensitive to ElectroStatic Discharge (ESD). Therefore care
should be taken during transport and handling. You must use a ground strap
or touch the PC case or other grounded source before unpacking or handling
the hardware.
3.4 Minimum system requirements
This evaluation board requires a Windows PC workstation. Meeting these minimum
specifications should produce great results when working with this evaluation board.
