sp32s Microcontroller Wifi & Bluetooth Esp Wroom 32 Development Board Module
In the world of IoT and embedded systems, the esp32-nodemcu is a standout tool for hobbyists, educators, and professionals alike. This development board combines the powerful ESP32 microcontroller with the accessible layout of NodeMCU form factor, delivering unmatched flexibility. Whether you're building a smart home device, a weather station, or robotics, this board enables seamless connectivity via Wi-Fi and Bluetooth while offering ample GPIO and peripheral support.
What Makes the esp32-nodemcu Great?
At its core, the esp32-nodemcu board uses the robust ESP32 microcontroller—a family of low-cost, high-performance chips integrating Wi‑Fi and Bluetooth. The ESP32 is powered by dual-core Tensilica processors (LX6 or RISC‑V), operates up to 240 MHz, and delivers up to 600 DMIPS. Each chip also includes ultra‑low‑power co‑processors, SRAM, Flash, and a rich set of peripherals including ADC, DAC, touch sensors, secure boot, and hardware cryptography support.
The NodeMCU form factor modernizes development by presenting the ESP32 in a breadboard‑friendly layout with USB‑to‑serial integrated, allowing instant program uploads and debugging. One widely adopted version is the NodeMCU‑32S, which exposes all I/O pins, includes reset and function buttons, and supports programming via Lua, MicroPython, Arduino, and more.
Key Features of esp32-nodemcu
