Feature
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, to make big project with big library. You do not need to worry about the size of the memory.
Onboard have USB-TTL serial converter CH340G, with -USB socket.
PowerIn for DC 4~9V, to pin VIN.
Pin headers 2.54mm (0.1′) 15 pins x 2 lines inset. Don’t solder.
It combined features of WI-FI accesspoint and station + controller and uses simple LUA based programming language.
WIFI NodeM ESP8266+extra memory, offer
For Arduino-like hardware I/O. And can programming in for Arduino IDE
Event-driven API for network applications
10 GPIO’s D0-D10, PWM functionality, IIC, and SPI communication, 1-Wire and ADC A0, etc. all in one board
Wi-Fi networking (can be used as an access point and/or station, host a web-server), connect to the internet to fetch or upload data.
For development can use install to the breadboard.
