ESP8266 Development Board

Description

About this item:

The NodeMCU ESP8266 development board is a popular and versatile platform for building Internet of Things (IoT) applications. It integrates the ESP8266EX microcontroller with built-in Wi-Fi, allowing direct connection to the internet without the need for additional modules. Based on the ESP-12E module, it comes with an onboard USB-to-serial interface (commonly CP2102 or CH340), enabling easy programming through a micro-USB cable.

Key Specifications:

• Microcontroller: ESP8266EX (Tensilica L106 32-bit, single-core)

• Operating Voltage: 3.3V (board accepts 5V via USB or VIN pin)

• Wi-Fi Connectivity: IEEE 802.11 b/g/n with integrated TCP/IP stack

• Flash Memory: Typically 4MB (varies by manufacturer)

• GPIO Pins: 17 configurable pins supporting PWM, I2C, SPI, UART, and ADC (1 channel)

• Clock Speed: 80 MHz (overclockable to 160 MHz)

• USB Interface: Micro-USB with onboard USB-to-UART converter (CP2102/CH340)

• Programming Support: Arduino IDE, NodeMCU (Lua scripting), MicroPython, and PlatformIO

• Power Consumption: Low-power modes supported for battery-driven projects

Features & Benefits:

• Integrated Wi-Fi for wireless IoT projects

• Breadboard-friendly design with pin headers for easy prototyping

• USB plug-and-play support for programming and power supply

• Wide ecosystem with libraries, firmware, and community support

• Suitable for home automation, sensor networks, smart devices, and rapid IoT prototyping
