I wonder why they chose to use the tiny watch-size amoled board for this. Wouldn't a multi effect UX be better with one of the 4-7" touchscreen boards?
Also: Am i reading it right that you can get an ESP32 with a 7" touch screen for like $30?
It's the author here. AMOLED is beautiful to look at. And you can stick this device on your guitar. Having said that, the same code can be compiled to any ESP32-S3, even headless boards, to use in a custom pedal (like the ones with Daisy Seed 3). CoyoPedal uses Gea Stack that allows us to target any device, including macOS and even the web, https://coyopedal.playtaurus.com has the exact same DSP and UI code built for WebAssembly.
