Description Links Bijlagen

The NodeMcu is an open source card with an integrated WIFI ESP-12E module. It is not a weak like the Arduino, with 512 KB of memory and a processor at 40Mhz there is no shortage of sources. This sign is extremely suitable for starting IoT (Internet of Things) applications. The programming of NodeMcu is slightly different from normal, with the API which resembles NodeJS, this module receives commands via the LUA scripts being downloaded.

This concerns version 2 of the NodeMCU series, thinner than the previous version and therefore better suited to a breadboard. Now there is a row on both sides of the board when you place it in the middle of a bread board. This saves a lot by connecting I / O.
