NXP Semiconductors PCA9422-EVB Evaluation Board

NXP Semiconductors PCA9422-EVB Evaluation Board is an easy-to-use circuit board allowing the user to exercise all the functions of the PCA9422 Power Management IC (PMIC). The PCA9422 PMIC is designed to streamline energy management in low-power microcontroller applications such as the i.MX RT500/RT600/RT700 and other compact systems. The NXP PCA9422-EVB supports Arduino® UNO interfaces. An onboard analog-to-digital converter (ADC) is used to monitor all regulator voltages through the Graphical User Interface (GUI).
