WI-FI NodeM ESP8266 + additional memory, the module is based on Expressif's widely explored esp8266 system.
WI-FI NodeM ESP8266 + additional memory, compatible with NodeMCU card. We add an additional memory size to 32MB (megabits). Best to do a big project with a big library. You don't need to worry about memory size.
The CH340G USB-TTL serial converter, with Micro-USB socket, is integrated.
PowerIn for DC 4 ~ 9V, to pin VIN.
Spindle heads 2.54 mm (0.1 ") 15 pins x 2 lines. Do not solder.

It combines the functionality of WI-FI access point and station + microcontroller and uses a simple programming language based on LUA.
WIFI NodeM ESP8266 + additional memory, offers:


Event API for network applications
10 GPIO D0-D10, PWM functionality, IIC and SPI communications, 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 retrieve or download data.
For development can be used with breadboard.
