3.1 Quick Start Setup

The following instructions describe how to set up and use the EVM.

  1. Purchase an SCB.
    1. To use a PAMB Controller instead, see PAMB Compatibility.
  2. Download the following driver and install as an administrator: https://www.ti.com/lit/zip/sbac253.
    1. Follow the download prompts, a myTI™ account is required.
    2. Note that this driver is labeled as a PAMB driver, but is also used for the SCB.
  3. Attach the EVM to the SCB Controller as shown in Figure 3-1.
    1. Refer to Figure 3-2 when connecting multiple EVMs of the same type together.
  4. Connect the EVM to the PC using the provided USB cable.
    1. Insert the micro USB cable into the SCB Controller onboard USB receptacle J2.
    2. Plug the other end of the USB cable into a PC.
  5. Access the GUI from this link in either Chrome™, Firefox™, or Safari™: https://dev.ti.com/gallery/info/CurrentSensing/INA233EVM_GUI/.
  6. Connect the GND reference of the external system to the GND node of the EVM (pin 1 of J1).
  7. Provide a differential input voltage signal to the IN+ and IN– nodes by connecting the signal leads to J1 pin 5 or 6 and J1 pin 3 or 4 on the EVM as explained in Current Sensing Operation.
