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.
