This is the wide variant of NodeMCU ESP8266, it is recommended to get Base IO Expansion Board for NodeMCU V3 to extend all the GPIOs for easier prototyping. Note that this form factor cannot be directly fit on a single breadboard. This NodeMCU ESP8266 board is equipped with CH340 serial interface chip, it is plug and play once connected to PC and its driver should be automatically installed and recognized (in newer Windows PCs and laptops).

If you want to get started in learning to build IoT system, this is the board you can get started with!

ESP12E Dev Kit is based on the development of ESP8266 which is an ultra-low-power UART-WiFi module. It?s designed for mobile devices and networking applications, usually it can be applied to the Internet, LAN communications, smart home fields, industrial control, and other handheld devices. ESP12E DevKit selects the on-board PCB antenna package with 2.54 in-line package, so that it can debug equipment or direct product applications conveniently. ESP12E Dev Kit encapsulates ESP8266 hardware operation API by Lua language, which could enhance the ability of developers to quickly design products.
