The INA219EVM is an evaluation module that is used to fully evaluate the INA219 current/power monitor

device. The INA219EVM consists of two printed circuit boards (PCBs). One board (the USB DIG Platform)

generates the digital signals required to communicate with the INA219, which is part of the second board

(INA219_Test_Board), as well as support and configuration circuitry.

Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with

the INA219EVM.
