• Powerful ESP32-DOWD-V3 Core: The ESP32-Uno is built around the ESP32-DOWD-V3 chip, offering a compact, Arduino Uno-sized form factor. It features a 4MB SPI Flash memory and integrates a single-chip solution with 2.4 GHz Wi-Fi and dual-mode Bluetooth.
• Integrated Motor Control: This board is equipped with two channels for encoder motors and two channels for DC motors. The two DC motor ports (M0, M1) can deliver a maximum current of 1.2A. A convenient slide switch on the board allows for easy toggling between motor driver and IO pin functionality. The driver pins for the two encoder motor ports (E0, E1) share connections with the DC motor ports. Specifically, E0 uses pins A:19, B:18, +:27, -:13, and E1 uses A:23, B:5, +:4, -:2.
• Modern Connectivity: Featuring a Type-C USB port that supports C2C data cables, the board also includes the reliable CH340G chip for serial communication.
• Extensive IO Support: The ESP32-Uno provides access to 22 GPIO pins, including: 0, 2, 4, 5, 12, 13, 14, 15, 16, 17, 18, 19, 23, 25, 26, 27, 32, 33, 34, 35, 36, and 39.
• Versatile Power and Dimensions: The board supports a 5.5-2.1mm DC jack for power input, accepting voltages from 6V to 16V. With product dimensions of 68.6 x 53.4mm, it is fully compatible with the Arduino Uno mainboard size.
