Theory of Operation
A block diagram of the OPT3006EVM hardware is shown in
. The OPT3006EVM contains an
FPCB (labeled MHR046), with a mounted OPT3006. This FPCB has a cutout that allows light to pass
through and illuminate the sensor. The OPT3006EVM also contains connections for the power, I
2
C, and
an interrupt signal. For evaluation purposes, the board also has a 5-pin header that allows the
OPT3006EVM to be connected to hardware other than the SM-USB-DIG Platform.

Hardware Overview
If not already assembled, the basic hardware setup for the OPT3006EVM involves connecting the
OPT3006EVM to the SM-USB-DIG Platform and then connecting the USB cable. This section presents
the details of this procedure.
CAUTION
Many of the components on the OPT3006EVM are susceptible to damage by
electrostatic discharge (ESD). Customers are advised to observe proper ESD
handling precautions when unpacking and handling the EVM, including the use
of a grounded wrist strap at an approved ESD workstation.
