The EVM is an easy-to-use platform for evaluating the main features and performance of the INA226. The EVM supports current measurements up to 10 amps through the PCB, and includes a graphical user interface (GUI) used to read and write device registers as well as view and save results data.

The EVM is intended to provide basic functional evaluation of the devices. The layout is not intended to be a model for the target circuit, nor is it laid out for electromagnetic compatibility (EMC) testing. The EVM consists of two printed-circuit boards (PCBs). The larger PCB is referred to as the EVM, and has the INA226 installed. The smaller PCB is referred to as the SCB Controller, and is used to interface the EVM with the GUI.
