Hi,

I am using the module DRV8889-Q1 for my heads up display project, can you please suggest a power supply that can be procured off the shelf?

Thank you,

Hi Arshiya,

This is really a system level question, as we do not know the final voltage and current targets.

Sure! But I just want to know the type of the connectors required for the supply.

Hi Rick,

I have found a power supply off-the-shelf for the DRV8889-Q1EVM, can you please verify if this can be used for operating the board?

More details about the stepper motor and supply to be used along with DRV8889-Q1:

Hi Arshiya,

Yes, the power supply will work with the stepper described.

Using the female terminal connector provided by the supply to connect wires from the connector to the EVM will complete the circuit.

Hi Rick,

Thank you for the reply.

My DRV8889-Q1 EVM got delivered today, I am making an initial setup to drive my motor. I have some questions:

1. To drive the motor uisng MSP430 onboard, do I have to supply 3.3V to the first pin on J3 header?

2. If I decide to use a external controller (Beagle Bone in my case) what are the steps I need to follow? I found the below text in the user manual for using external micro, but how do I remove the resistors from the PCB?

3. For driving the motor in the step mode configuration, what are the absolute necessary parameters I need to configure from the GUI(for just spinning the motor demo)?

4. In the GUI,we have two options for "Step and Direction Control"- GPIO, SPI, which to use when?

I look forward to your response.

Thank you,

Arshiya Tabassum
