SKU: IOT-NODEMCU Category: Tags: , ,


NodeMCU is designed based on ESP-12E ESP8266 WiFi SoC. It is an open-source firmware and development kit that helps you to prototype your IoT (Internet of Things) products within a few LUA script lines. NodeMCU is now compatible with Arduino IDE thanks to the contributions by developers and contributors so you can use it with Arduino IDE without hassle.

NodeMCU can also be used with PlatformIO. You can explore this tiny but powerful IoT microcontroller with PlatformIO IDE.

NodeMCU is the fastest leading edge low cost technologies to WiFi enabled IoT. Modern high-level mature LUA based technology. It is an integrated unit with all available resources on board. It is super simple to complement your existing Arduino projects or any development board that has I/O pins available. Modern Internet development tools such as Node.js can take advantage the NodeMCU with the built-in API to put your idea on the fast track immediately.

NodeMCU has ESP-12 based serial WiFi integrated on board to provide GPIO, PWM, ADC, I2C and 1-WIRE resources at your finger tips.
