I have an ESP32-S31 devkit with a 480 x 480 OLED touchscreen, haptic motor, and a battery. Write ESP-IDF firmware that draws a touch-driven menu on the display, triggers a short haptic pulse on each tap, and shows battery level in the corner. Structure the code so I can add a camera module later.

Story

Espressif's ESP-Mosaico is a modular development board built around the ESP32-S31, and it comes with a 480 × 480 OLED touchscreen, haptic feedback and a built-in battery. The pitch is explicit: it's aimed at "Chat" and "Vibe" AI coding, so you describe what you want and let a model write the firmware for the screen and hardware.

The board has USB Type-C connectivity and expansion I/O for a camera module, so the screen and sensing can grow past the base kit. For anyone who wants a self-contained handheld prototype with a touch display and a battery already on board, that's the appeal: the hardware is the starting point, not the project.
