ESP8266 CH340 NodeMCU Wi-Fi Development Board

The NodeMCU ESP8266 CH340G Wifi Development Board is based on ESP8266 and is one of the easiest way to get started with ESP8266 and WiFi related projects. This module uses one of the highest used ESP8266-12F, which can be found in many of IoT devices nowadays. The module has Micro USB Interface. It has dual use, for connection with PC, as well as for Input power supply. It has onboard 3.3 V regulator, and therefore can be supplied with up to 14 V DC. Also NodeMCU is an open-source firmware and WiFi Development Board kit. And it can help anyone in learning and prototyping of IoT and WiFi based products with Lua Script Lines.

NodeMCU has ESP-12 based serial WiFi integrated on board to provide GPIO, PWM, ADC, I2C and 1-WIRE resources at your fingertips, built-in USB-TTL serial with super reliable industrial strength CH340 for superior stability on all supported platforms. This module is one of the cheapest available wifi-modules in the market.

The NodeMCU ESP8266 development board comes with the ESP-12E module containing the ESP8266 chip having Tensilica Xtensa 32-bit LX106 RISC microprocessor. This microprocessor supports RTOS and operates at 80MHz to 160 MHz adjustable clock frequency. NodeMCU has 128 KB RAM and 4MB of Flash memory to store data and programs. Its high processing power with in-built Wi-Fi / Bluetooth and Deep Sleep Operating features make it ideal for IoT projects.

NodeMCU can be powered using a Micro USB jack and VIN pin (External Supply Pin). It supports UART, SPI, and I2C interface.
