The DRV841xEVM comes with various features for facilitating the validation of the DRV841x family of low voltage stepper motor drivers. Below is a list of the features included in this family of EVM:

• 3.3 V LDO for supplying power to digital circuitry.
  Note: The DRV841x family of devices can operate as low as 1.65 V. If the power supply is less than 3.3 V, an external 3.3 V supply is required.
• Onboard eZ-FET lite circuit for MSP debugging. The eZ-FET lite allows for programming the MCU with a custom code via USB. No external hardware tool is required for programming. This eZ-FET lite circuit also facilitates updating of firmware when a new version of the firmware is available.
• Graphical User Interface (GUI) to control the driver input signals (nSLEEP, AIN1, IN2, BIN1, BIN2). More information regarding the GUI in Section 5.
• Main signal header with tests points and shunts to easily remove the signal connections between the driver IC and the MCU. User can connect external MCU to control the motor driver on the EVM. More details are shown in Section 2.
• Hardware is design so that the driver can be set to dual h-bridge and parallel h-bridge control by header jumper settings and GUI. The different control modes are explained in Section 5
• Test points for most important signals such as the control inputs, driver output, power supplies, LDO output, and so forth. for ease of measurement.
