Details

WI-FI NodeM ESP8266+extra memory, module is based on widely explored esp8266 System on Chip from Expressif.
WI-FI NodeM ESP8266+extra memory, compatible for NodeMCU board. We add extra memory size to 32Mb (Megabit). This better, for make big project with big library. You not need to worry about size of memory.
On board have USB-TTL serial converter CH340G, with Micro-USB socket.
PowerIn for DC 4~9V, to pin VIN.
Pin headers 2.54mm (0.1") 15 pins x 2 lines in set. Don't soldered.

It combined features of WI-FI accesspoint and station + microcontroller and uses simple LUA based programming language.
WIFI NodeM ESP8266+extra memory,, offer:

Arduino-like hardware I/O. And can programming in Arduino IDE
Event-driven API for network applicaitons
10 GPIO's D0-D10, PWM functionality, IIC and SPI communicaiton, 1-Wire and ADC A0 etc. all in one board
Wi-Fi networking (can be uses as access point and/or station, host a web-server), connect to internet to fetch or upload data.
For developing can use install to breadboard.
