To use the EVM with the SCB Controller (sold separately), connect the EVM as shown in
Figure 2-1. EVM (Bottom) Connected to SCB Controller (Top)
If using multiple EVMs, then connect them as shown in
address for each device. The GUI only supports one EVM or device type at a time; up to four EVMs total.
2.2.1 Current Sensing Operation
These EZShunt digital power monitor EVMs come equipped with internal shunt resistors and are out-of-the box
ready to measure up to 25 A (INA74x devices) or 50 A continuous current (INA78x devices) up to the rated
input common-mode voltage. The EVMs have exposed pads (MP1 and MP2) for IS+ and IS- pins to run current
through. MP1 and MP2 are designed for terminal connector lugs compatible with a 1/4 inch stud, such as the
LAMA6-14-QY.
Note that the VBUS pin is electrically tied to the IS+ net
