DRV8213EVM: DRV8213-14-34EVM suggestion for improvement

Part Number: DRV8213EVM

While the EVMs for DRV8213-14-34 parts are OK, they would be much more useful if some of the many unused pins on the MSP430 were made accessible. This would allow them to be used for more flexible prototyping.

Even better, it would be nice if the EVMs were split into two parts, a motherboard with the MSP430 shared among all the parts and a daughter board for each part. Possibly the motherboard could even be an existing eval board for the MSP430. Most of the cost of the eval boards is presumably the MSP430 and associated debugger. Breaking them down could greatly reduce the cost of the really useful part.

Even better still, make the daughter boards Arduino connector compatible.

    Hi Robert,

    Thank you for taking the time to post your thoughts with the DRV8213-14-34 EVMs and potential hardware features mods suggestions. We appreciate it. In the past we had some TI MSP430 Launchpad compatible plug-in EVMs but the demand on them was pretty low. Eventually we settled on the current hardware architecture and provided a two row header to isolate the driver and the on-board MSP430 to allow users to connect to their MCU systems. Good point on providing access to the additional unused MSP430 GPIO ports. We'll keep this is in mind for our next design. 

    We use TI MSP430 as well as we built in the ez430 debugger interface onboard such that it works seamlessly with CCS https://www.ti.com/tool/CCSTUDIO for code development. You have the flexibility to work with the EVM and CCS with no additional hardware required. We also provide the CCS project files and complete source code for download in the corresponding EVM webpages. 

    Thanks again for your suggestions.

    Regards, Murugavel
