GPIO Map
Overview
The DFRobot Romeo ESP32-S3 is a robotics-focused development board that integrates an ESP32-S3-WROOM-1U module (dual-core LX7 @ 240MHz, 16MB flash, 8MB PSRAM) with a four-channel 2.5A H-bridge motor driver on a single board. This combination eliminates the need for separate motor driver shields, making it a compact and capable controller for 2WD and 4WD robot platforms.
The board includes an OV2640 camera (or OV3660 alternative) with a dedicated power circuit for FPV and computer vision applications, WiFi 802.11 b/g/n and Bluetooth 5 for wireless control, a microSD card slot for data logging, and a GDI connector for direct display integration. The motor driver supports both PH/EN and PWM control modes with a separate VM power rail (5-24V), while multiple servo connectors with stable 5V/2A output enable multi-servo operation.
Designed for Arduino IDE and ESP-IDF development, the Romeo ESP32-S3 brings together motor control, vision, wireless connectivity, and AI capabilities in a single board. Its 27 GPIO pins, dual 12-bit ADC (20 channels), I2S, SPI, I2C, and UART interfaces provide ample expansion for sensors and peripherals. The board is well suited for educational robotics, autonomous navigation projects, and WiFi-controlled robot builds.
