Can an Itsy Bitsy drive servos and play sounds simultaneously?

Post by WShawn »

I have this PKE Meter prop that's (mostly) working and is driven by a Teensy 3.2 and PJRC Prop Shield LC. It uses servos to drive the wings, chases LEDs, and plays two sound clips stored on the flash on the Prop Shield.

As I'm considering building several more of these, or maybe offering kits, I'm looking to replace this setup with another microcontroller as the Teensy 3.2 won't be available again for many months due to the chip shortages.

I'm hoping some flavor of an Itsy Bitsy and a mono amp can do this, but I'm concerned this line might not have the ability to play sound and drive servos at the same time. Page 15 of this PDF indicates the servo functions interfere with sound playback.

I'm prepared to redesign my schematics and PCBs to switch over to a more stable microcontroller supply.

I'm pretty green when it comes to coding this stuff and whatnot; I've had a friend do most of that heavy lifting.

Thanks!
