Which ESP to use for audio sequencer?

[nathanw]

Hi there.

I want to make an audio sequencer with an ESP32. It will need to:

- Read audio (WAV is fine) probably from an SD-Card
- Play audio (headphone and/or speaker)
- Trigger sounds via button inputs
- Possibly a screen/display

I currently only have basic experience with a standard ESP-32 running ESP-IDF.

I've been reading through the ESP ADF and it has a bunch of the feature I want. It also recommends the ESP32-LyraT V4.3 (https://docs.espressif.com/projects/esp ... lyrat.html). However, it's not clear to me if there are any I/O pins that I can play with.

From this video (https://www.youtube.com/watch?v=MpDe5XtKSMw) I gather that there aren't a lot of GPIO pins to play with?

Also I'm very new to embedded. Any advice would be appreciated!

Thanks.
