The ESP8266 NodeMCU is a low-cost Wi-Fi microcontroller perfect for lightweight IoT robotics. It’s powered by a 32-bit Tensilica CPU and integrates GPIO, ADC, PWM, and SPI/I2C. Often used in remote sensors, robot telemetry, and automation interfaces.
Product Description
The ESP8266 NodeMCU is a low-cost, open-source Wi-Fi development board based on the ESP8266 microcontroller. Designed for rapid IoT prototyping, it integrates the ESP-12E module, a USB-to-serial converter, and a voltage regulator, all on a compact PCB with breadboard-friendly headers. Powered by the Tensilica L106 32-bit RISC processor, the NodeMCU supports clock speeds up to 80/160 MHz, features 11 GPIO pins, SPI, I²C, PWM, ADC, and supports deep sleep modes for low-power applications. It comes preloaded with the NodeMCU firmware, which allows programming in Lua, though it's most commonly used with the Arduino IDE thanks to its wide support and ease of use. The onboard micro-USB port provides power, programming, and serial communication. Ideal for IoT applications, home automation, sensor nodes, and Wi-Fi-enabled projects, the NodeMCU offers an excellent balance of power, price, and flexibility for beginners and advanced developers alike.
