I want to mount both an Adafruit I2S speaker bonnet and Adafruit I2S microphone on a Raspberry Pi 3. I have tested and both work independently. But both use the same pins 18 and 19, and I don't see anywhere in the installation code of the speaker or the microphone any mention of pins 18 or 19. The latter has 12, which is 18 in hexadecimal, but not 13. The former has neither.

Can I mount both on a Raspberry Pi? Or would I need another type of microphone, such as a USB plug-and-play microphone?

Note: this thread mentions a similar problem, but I don't see which pins are used.
