NodeMcu CP2102 Lua WI-fi ESP8266

Deska pro pokročilé. Open-source, Interactive, Programmable, Low cost, Simple, Smart, WI-FI enabled.
Arduino-like hardware IO 
Advanced API for hardware IO,  which can dramatically reduce  the redundant work for  configuring and manipulating  hardware. Code like arduino,  but interactively in Lua script. 
Nodejs style network API
Event-driven API for network applicaitons, which faciliates developers writing code running on a 5mm*5mm sized MCU in Nodejs style. Greatly speed up your IOT application developing process.
Lowest cost WI-FI
Less than $2 WI-FI MCU ESP8266 integrated and esay to prototyping development kit. We provide the best platform for IOT application development at the lowest cost.
Development Kit
The 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!
