WIFI NodeM ESP8266+32Mb, module is based on widely explored esp8266 System on Chip from Expressif.
WIFI NodeM ESP8266+32Mb, compatible for NodeMCU board. We add extra memory size to 32Mb. This better, for making a big project with a big library. You do not need to worry about the size of memory.
Onboard 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 solder.
It combined features of the WIFI access point and station + microcontroller and uses simple LUA based programming language.
WIFI NodeM ESP8266+32Mb, offer:
Arduin0-like hardware IO. And can programming in Arduin0 IDE
Event-driven API for network applications
10 GPIOs D0-D10, PWM functionality, IIC, and SPI communication, 1-Wire and ADC A0, etc. all in one board
Wifi networking (can be used as an access point and/or station, host a web server), connect to the internet to fetch or upload data.
