The Texas Instruments DRV8829EVM board is an evaluation board and demo kit designed to enable quick and easy use of the Texas Instruments DRV8829 low voltage motor driver devices. It is intended to demonstrate the capabilities of the device, while offering users ease of use and quick development. The board is designed to work with a variety of power sources, including a 5 to 40V regulated or unregulated DC power supply, battery supplies, and even USB power from PCs and other devices.

The board is designed with two motor channels, allowing for two brushed DC motors to be controlled independently. The board also integrates a number of features to allow users to quickly debug and evaluate the capabilities of the device, including a logic level shifter to connect to control systems with different logic levels, a serial connected debug header, a USB powered logic high voltage supplies, and an optional battery pack.

The DRV8829 device itself combines a low-side current sensing block and controller functions that enables brush-DC motor control. The low-side current sensing block provides precise current regulation without the need for a dedicated current sensing resistor and the controller functions include motor direction, speed control, and obstacle detection logic. The device has an adjustable peak current limit, and allows for pulse-width modulation (PWM) control of the driver outputs. Additionally, the device can also provide regulated output voltage to power external components, such as microcontrollers.

The board is easy to use and program, and is well suited for use in applications such as robotics, automated control systems, and general low-voltage motor control. It provides a great means for users to quickly evaluate and develop applications that require the use of the DRV8829 low-voltage motor driver, and provides a platform for users to quickly develop and debug their applications without needing to undergo a costly PCB design cycle. The board is also well-suited for use in educational environments, and hands-on demonstrations of the capabilities of the DRV8829 motor driver.
