Quick Overview
The DIYables ESP32 Development Board is a compact 30-pin microcontroller board powered by the Espressif ESP32 chip with integrated 2.4 GHz WiFi and Bluetooth dual-mode wireless connectivity. It features a CH340 USB-to-serial chip paired with a USB Type-C connector for reliable, reversible programming and power delivery. The board comes with presoldered header pins, so it is breadboard-ready straight out of the box with no soldering required.
The board includes an onboard antenna, RF components, and power management circuitry for efficient operation in a compact form factor. It exposes 30 pins covering GPIO, ADC, DAC, I2C, SPI, UART, and PWM, giving access to the full range of ESP32 peripherals. The USB Type-C interface works with the CH340 driver to provide stable serial communication at standard baud rates.
Ideal for IoT projects, wireless sensor nodes, home automation, robotics, and prototyping. Compatible with Arduino IDE (C/C++) and MicroPython, with tutorials available to help developers get started quickly on ESP32-based projects.
