4.3 Motherboard
4.3.1 Schematic
shows the complete schematic of the OPTMBEVM motherboard. The schematic is split into three
sections: connector, MSP430, and socket. A USB type C connector is used to interface with the PC. The
MSP430 microcontroller allows the PC to interface with the OPT3004DTS through I2C. The coupon board
containing the OPT4001 plugs into the motherboard through the socket. The OPTMBEVM board provides easy
access to the I2C, INT, VDD, and GND lines. The header J2 is depopulated on the EVM by default and its
labeled through hole pads can be used to access the lines. Alternatively, a header can be populated at J2 for
easier access.
