2.1 Connections Overview

The major blocks of the EVM include the DRV824x-Q1 or DRV814x-Q1 driver, MSP430G2553 microcontroller (MCU) controlling the driver, and MSP430F5528 (EZFET_LITE) for UART and JTAG communications over USB.

The EVM is designed for an input supply from 4.5 to 36 V at the rated peak drive current for each device (refer to device data sheet). The DRV824x-Q1 or DRV814x-Q1 device provides current to a brushed DC motor or other load. The MCU communicates with the GUI via the EZFET_LITE USB to Virtual COM Port (VCP) to control the DRV824x-Q1 or DRV814x-Q1 device.
