ESP32 Development Board 30 Pin WiFi Bluetooth

Overview

The ESP32 30-Pin Micro Development Board (WiFi + Bluetooth, Dual-Core 240MHz) is an exceptionally powerful, breadboard-friendly IoT development platform powered by Espressif's flagship ESP-WROOM-32 module. Featuring a blazingly fast dual-core 32-bit Xtensa LX6 processor running at up to 240MHz, built-in 2.4GHz Wi-Fi (802.11 b/g/n), and dual-mode Bluetooth v4.2 (Classic + BLE), this board delivers enterprise-grade computing power for a fraction of the cost of traditional boards. Designed with 30 breadboard-friendly pin headers, an onboard micro-USB port, and rich peripheral interfaces (ADC, DAC, PWM, I2C, SPI, UART, capacitive touch), the ESP32 is the premier choice for modern IoT, smart home automation, remote robotics, and edge computing projects.

Key Features

• High-Performance Dual-Core LX6 Processor: 240MHz dual-core architecture allows one core to manage wireless networking while the second core runs sensor loops and user code with zero latency.
• Dual-Mode Wireless Connectivity: Integrated 2.4GHz Wi-Fi and Bluetooth Low Energy (BLE) enable seamless cloud telemetry and direct smartphone control.
• Generous On-Chip Memory: 520 KB SRAM and 4 MB SPI Flash comfortably store rich web servers, OTA firmware updates, and complex networking stacks.
• Compact 30-Pin Form Factor: Fits on standard solderless breadboards with an exposed row of tie-points for easy jumper wire connections.
• Rich Analog & Digital Peripherals: 25 versatile GPIO pins supporting 12-bit ADC channels, 8-bit DAC outputs, capacitive touch pads, and hardware PWM.
