ESP32 Development Board – Wi-Fi & Bluetooth

What it is
The ESP32 Development Board – Wi‑Fi & Bluetooth is a compact, dual‑core 32‑bit microcontroller built around the ESP‑WROOM‑32 module. With a Tensilica LX6 processor running up to 240 MHz, 4 MB of flash, 520 KB of SRAM, and 30–38 GPIO pins, it delivers the power of a full‑featured computer in a board that fits in the palm of your hand. It supports Wi‑Fi 802.11 b/g/n and Bluetooth 4.2 (BR/EDR + BLE), making it ideal for IoT, smart‑home, robotics, and edge‑AI projects. The board works with Arduino IDE, MicroPython, ESP‑IDF, and PlatformIO, so students can choose the language and environment that best fits their skill level.

What students will learn
Using the ESP32, learners explore real‑world concepts across science, technology, engineering, art, and math: they program wireless communication protocols, design sensor networks, create cloud‑connected dashboards, and implement multitasking with a dual‑core CPU. Hands‑on projects teach data acquisition with ADC/DAC, motor control via PWM, and touch sensing, while also introducing fundamentals of networking, security, and low‑power design. By the end of a module, students can prototype a working IoT device—from a Bluetooth‑controlled robot to an AI‑enabled environmental monitor—and understand how software and hardware collaborate in modern embedded systems.

Key features & STEAM benefits
