ESP8266 serial wifi module NodeMcu Lua wifi V3 CH340

Product highlights:

1. Open-source, Interactive, Programmable, Low cost, Simple, Smart, WI-FI enabled.
2. NodeMCU is an open source IoT platform that uses the Lua scripting language. NodeMCU is a development board featuring the popular ESP8266 WiFi chip. You can program the ESP8266 just like any other microcontroller. Its obvious advantage over the Aduino or PIC is that it can readily connect to the Internet via WiFi. However, the ESP8266 breakout board has limited pins although the chip itself has a lot of output ports. The NodeMCU solves this problem by featuring 10 GPIO pins each capable of using PWM, I2C and 1-wire interface.

Technical Specifications:
The Development Kit based on ESP8266, integates GPIO, PWM, IIC, 1-Wire and ADC all in one board.
USB-TTL included, plug&play.
10 GPIO, every GPIO can be PWM, I2C, 1-wire
PCB antenna
