Part Number: AWR1843

I want to connect AWR1843Boost EVM directly with a buzzer. The buzzer type is not fixed.

The use case is when the EVM detects the obstacles, then make a simple alarm beep.

I don't know if is it possible and what buzzer type can be directly connect with AWR1843Boost EVM.

If it is possible or there is an example demo, could you please give a guidance?

Kind regards

Ree,

The AWR1843BOOST has two GPIO pins (GPIO0 and GPIO1) that are accessible through the two 20-pin headers on the backside of the board.

You can find more information in the EVM User Guide here: https://www.ti.com/lit/ug/spruim4b/spruim4b.pdf

You can refer to the GPIO drivers folder in the SDK for unit test examples on configuring the GPIO pins as input or output.

You can additionally refer to the AWR1843 datasheet for information on the electrical characteristics of the I/Os.

Regards,

Kyle
