NodeMCU

NodeMCU - (MCU = stands for MicroController Unit(which really means it is a computer on a single chip)) NodeMCU is an open source platform based on ESP8266 which can connect objects and let data transfer using the WiFi protocol.  NodeMCU is an open source firmware and development kit that helps you to prototype or build IOT products. The NodeMCU development board can be easily programmed using the Arduino IDE Microcontroller - ESP-8266 32 bit clock speed = 80 Mhz operating voltage = 3.3 volts input voltage = 4.5 - 10 volts FlashRAM(SRAM) - 4MB/64Kb Digital i/o pins - 11 Analog i/o pin - 1 ADC Range - 0 - 3.3 volts Application Prototyping of IoT devices Low power battery operated applications Network Projects Project Requiring multiple i/o interfaces with wifi module and bluetooth facilities
