The GPIO numbers on the ESP32 are universal, and our M5Stack firmware uses the ESP32 core, so you should have access to all the GPIO. Just don't use ones that aren't exposed in hardware and you should be good to go.

@pbruno3 Understood on the IO side of things, but right now I'm just trying to get the LCD to work. I think they kept SDA/SCL on the same GPIOs but changed the backlight power connection and a few other things. I found a comparison of the M5Stack (used by the Grey) and M5Core2 (used by the Tough). Backlight used to run off GPIO32, but now its handled by a power management chip instead. Diagram attached. Any chance you have an Arduino sketch version of the M5Stack firmware that you could share? I'd be happy to help update it for the M5Stack "Tough" and their new M5Core2 standard.

Oh, so the M5Core2 and the M5Stack have different pinouts it looks like?
