2.1 Connections Overview

The major blocks of the EVM include the driver (DRV824x-Q1, DRV826x-Q1, DRV816x-Q1, or DRV814x-Q1), 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 36V at the rated peak drive current for each device (refer to device data sheet). The DRV824x-Q1, DRV826x-Q1, DRV816x-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, DRV826x-Q1, DRV816x-Q1, or DRV814x-Q1 device.
