Specifications

Design and Construction

The ESP32 30-Pin Development Board features a compact and breadboard-friendly PCB layout that provides convenient access to the ESP32’s GPIO and peripheral interfaces.

The 30-pin configuration offers a balance between functionality and compact size, making the board suitable for projects where PCB space is limited while still requiring access to important communication and control pins.

The integrated CP2102 USB-to-UART converter provides a reliable interface between the ESP32 and a computer for firmware programming, serial monitoring, and debugging.

The USB Type-C connector provides a modern and reversible connection for programming and powering the board.

Working Principle

The ESP32 acts as the main processing and wireless communication controller for the project. Users can upload firmware through the USB Type-C interface using the onboard CP2102 USB-to-UART converter.

The processor can control connected sensors, LEDs, displays, motors, relays, and other peripherals using its GPIO and communication interfaces.

The integrated Wi-Fi and Bluetooth capabilities allow the board to communicate wirelessly with smartphones, computers, cloud services, sensors, and other connected devices.

The board can be programmed using Arduino IDE, ESP-IDF, MicroPython, and other supported development environments.

Communication Interfaces

The board provides multiple hardware interfaces for connecting external devices:

UART
