Romeo ESP32-S3 Robot Development Board

The Romeo ESP32-S3 from DFRobot is a robotics board with the ESP32-S3-WROOM-1U-N16R8 module (16 MB flash, 8 MB PSRAM), a motor driver for four DC motors with 2.5 A each and a connector for a camera. Wi-Fi and Bluetooth 5 (LE) allow remote control and video transmission, for example for a vehicle with a first-person view (FPV). The vector instructions of the ESP32-S3 speed up image and speech recognition on the board. It is programmed with Arduino IDE, ESP-IDF or MicroPython.
