2 OPTEVM Hardware Overview

Figure 2-1 shows the system setup for the OPTEVM. The computer runs the graphical user interface (GUI)
software that communicates with the OPTMB EVM board over a USB connection. The OPTMB EVM board
has a USB Type C port and ships with a USB-C to USB-A cable. The OPTMB EVM board acts as a bridge
between the software running on the PC and the OPTCB coupon board. The MSP430 on the OPTMB EVM
board receives USB commands from the PC and communicates with the light sensor over I
The OPTCB coupon board consists of the light sensor IC, decoupling capacitor, and 8 pins. The pins create
connections for the power, I
board. For evaluation purposes, the OPTCB coupon board can be removed from the OPTMB EVM board to use
with other platforms. The OPTMB EVM board also has an unpopulated 5-pin header footprint for easy access to

the supply, ground, I C, and interrupt lines.
The EVM ships with the OPTCB coupon board plugged into the motherboard. If not already assembled, then the
basic hardware setup for the OPTEVM involves plugging the coupon board into the OPTMB EVM board socket.
Take special care to make sure the OPTCB coupon board is oriented correctly as shown in
connect the USB cable. This section presents the details of this procedure.
Many of the components on the OPTEVM are susceptible to damage by electrostatic discharge
(ESD). Customers are advised to observe proper ESD handling precautions when unpacking and
handling the OPTEVM, including the use of a grounded wrist strap at an approved ESD workstation.
