From the Core2 to the 5 inch Tab5, many of M5Stack's modular ESP32 development kits are built around integrated touchscreens, which is why makers and engineers treat them as tiny finished products rather than bare boards. Prototypes live on cluttered benches and inside 3D-printed enclosures, so an M5Stack screen protector is sensible lab kit: anti-shock resilience for hands-on hacking, smudge-resistant finishes for long debugging nights, paper-feel texture for stylus prototyping and privacy for deployed installations where the display faces the public.
