  • Page 3: Overview

    This requires the sensor be soldered to a flex PCB in most applications to maximize the field of view of the sensor. The OPT4001YMNEVM is a platform for evaluating the performance of the OPT4001 under various conditions. The OPT4001YMNEVM consists of two PCBs.
  • Page 4: Related Documentation From Texas Instruments

    The following documents provide information regarding Texas Instruments' integrated circuits used in the assembly of the OPT4001YMNEVM. This user's guide is available from the TI web site under literature number SBOU278. Any letter appended to the literature number corresponds to the document revision that is current at the time of the writing of this document.
  • Page 5: Opt4001Ymnevm Hardware

    2 OPT4001YMNEVM Hardware Figure 2-1 shows the system setup for the OPT4001YMNEVM. The computer runs the graphical user interface (GUI) software that communicates with the OPTMBEVM board over a USB connection. The OPTMBEVM has a USB Type C port and ships with a USB-C to USB-A cable. The OPTMBEVM board acts as a bridge between the software running on the PC and the OPT4001YMN coupon board.
  • Page 6: Theory Of Operation For The Opt4001Ymnevm

    The EVM ships with the coupon plugged into the motherboard. If not already assembled, the basic hardware setup for the OPT4001YMNEVM involves plugging the coupon board into the motherboard socket. Take special care to make sure the coupon is oriented correctly as shown in Figure 1-1.
