The NodeMcu V3 Development Kit based on ESP8266, integates GPIO, PWM, IIC, 1-Wire and ADC all in one board. Power your developement in the fastest way combinating with NodeMcu Firmware.

• Build on ESP8266 sdk
• Lua core based on eLua project
• cjson based on lua-cjson
• File system based on spiffs
• Easy to access wireless router
• Based on Lua 5.1.4 (without debug, os module.)
• Event-Drive programming preferred.
• Build-in json, file, timer, pwm, i2c, spi, 1-wire, net, mqtt, coap, gpio, wifi, adc, uart and system api.
• GPIO pin re-mapped, use the index to access gpio, i2c, pwm.
• Both Integer version(less memory usage) and Float version(Default) firmware provided.

Features:

• Now supports the arduino IDE 1 with Arduino ESP8266
• WiFi Module – ESP-12E.
• USB – Power 5v and program via micro USB port
• Fits on a standard breadboard and gives access to a row of holes either side
• 10 GPIO, every GPIO can be PWM, I2C or 1-wire
• Headers – 2 x 2.54mm 15-pin header with access to GPIOs, SPI, UART, ADC, and power pins
• Misc – Reset and Flash buttonsDimensions – 49 x 24.5 x 13mm
• USB-TTL included, plug n playFCC CERTIFIED WI-FI module, PCB antenna
• Can see the Nodemcu LUA development environment as an alternative to the Arduino ESP8266
