NodeMcu v.3 ESP8266 + WiFi Review

The Nodemcu Lua V3 CH340 Wi-Fi module on Esp8266 is used to create wireless devices based on Arduino. It receives a Wi-Fi signal and sends data. Arduino IDE support. An ideal base for creating the Internet of things and other control modules over a wireless Wi-Fi network. The module provides 11 general purpose I/O ports. Some have additional functions: - D9, D10 - UART- D1, D2 - I2C/TWI- D5 - D8 - SPI- D1 - D10 - PWM outputs - A0 - ADC input (analogue). By default, the NodeMCU firmware of the same name is loaded into the platform. It has a built-in Lua scripting language interpreter, which sets the behavior of the board. The native voltage of the module is 3.3 volts. The board has a voltage regulator, so you can power it via USB or supply power from 3.7 to 20 volts to the 5V pin. Specifications: • Wireless interface: Wi-Fi 802.11 b/g/n 2.4 GHz; • Modes: P2P (client), soft-AP (access point); • Maximum output power: 19.5 dB mW (89 mW); • Rated voltage: 3.3 V; • Input voltage: 3.7 - 20 V; • Maximum current consumption: 220 mA; • Ports of input/output of free purpose: 11; • Processor frequency: 80 MHz; • Memory size for code: 64 KB; • The amount of RAM: 96 KB; • Dimensions: 45 x 30 mm; • The module supports USB 2.0.
