WIFI NodeMESP8266+32 Mbit (4 MB)(USB-TTLCP2102), module is based on widely explored esp8266 System on Chip from Expressif.
WIFI NodeMESP8266+32 Mbit (4 MB), compatible forNodeMCUboard. We add memory size to32 Mbit (4 MB). This better, for make normal project with big library.
On board have USB-TTL serial converterCP2102, 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 WIFI accesspoint and station + microcontroller and uses simple LUA based programming language.
WIFI NodeM ESP8266+32 Mbit (4 MB), offer:
Arduin0-like hardware IO. And can programming in Arduin0 IDE

Event-driven API for network applicaitons

10 GPIOs D0-D10, PWM functionality, IIC and SPI communicaiton, 1-Wire and ADC A0 etc. all in one board

Wifi networking (can be uses as access point and/or station, host a webserver), connect to internet to fetch or upload data.

For developing can use install to breadboard.
