Compatibility between Crowpanel 7.0 and Crowtail-Speaker
Hello,
Is it possible to plug the Crowtail Speaker on the Crowpanel 7.0 to play sounds? If so, on which connector? If not, is there a product on Elecrow that could go on the SPK port of the Crowpanel?
Have a great day,
- Mehdi

Hello @atrus2905 ,
Yes, you can connect to GPIO_D(IO38) which can output PWM
Thank you for your answer @Elecrow
However I have a servo plugged in GPIO_D in my setup, so I cannot use that one.
Can you suggest an alternative solution, please?
Hi @atrus2905
You can plug the speaker into the UART0 port, and generate the tone signal by delay. For more information, please refer to the wiki: https://www.elecrow.com/wiki/crowtail--speaker.html
