The Romeo Mini ESP32-C3 is a compact robot control board with an onboard ESP32-C3 module providing Wi-Fi and Bluetooth 5 dual-mode communication. It features two channels of 1.7A motor drivers, servo control, and 9 Gravity-compatible I/O interfaces — all in a tiny 47mm × 38.5mm form factor.

A built-in GDI interface on the rear supports IPS TFT display screens for showing project data. The board accepts 5–12V input and can power servos directly through a dedicated servo power port, making it a self-contained platform for small robotics projects.
