Description

WiFi NODEMCU ESP8266 Module with CP2102 (USB to Serial Converter)

Nodemcu V3 Lua WiFi Integrated ESP8266 Module + 32 M FLASH Memory, USB Serial Port CH340G

Modern WiFi ESP8266 + 32 MB, the module is based on a wide range of ESP8266 system chip from expressif. Modern WiFi ESP8266 + 32 MB, compatible with nodemcu board. We have added an additional 32 MB of memory. This is better for large library projects. No need to worry about memory size. On board there is a USB-TTL serial converter CH340G, mini USB port. DC 4 ~ 9 V PowerIn pin VIN. 2.54mm (0.1″) 15 X pin set. Do not solder. Combine WiFi access point and programming station + microcontrollers using simple Lua language. Modern WiFi ESP8266 + 32 MB, provides: Arduino hardware IO. Can be used in Arduino IDE event-driven API network application 10 D0-D10, PWM programming function, IIC and SPI communication, on a WiFi wireless network card and ADC (A0, etc can be used as an access point and/or station, host server), connect to the Internet, get or load data, and developing card use the mounting card.
