M5Stack Core2 (ESP32 + LCD tactile)

The M5Stack Core2 is an ESP32 already integrated in an enclosure with a touchscreen, battery and connectors — the shortcut to deliver a clean edge HMI without designing a board or plastics. Andon terminal, workstation display, operator input, local dashboard at the foot of the line: you go from sensor to a presentable interface in a few hours.

It is a closed, compact product: fewer free I/O than a bare board, and a fixed form factor. For a rich HMI (browser, large screen, multi-window), a Raspberry Pi with a touch panel is more capable. The Core2 wins when you want something finished, robust and fast to deploy on a specific function.
