Dubbed as “Witty Cloud”, the ESP8266 Serial Wi-Fi Witty Cloud Development Board ESP-12F Module, is a compact ESP8266-based module that is made of two stacked PCB boards connected by a pair of an 8-pin header.
The upper board is the main board which consists of an ESP-12F module – where ESP8266 Wi-Fi microcontroller is located, an RGB LED, an LDR, a button, a micro USB port and a 3.3V voltage regulator.
The lower board mounts the CH340G USB-to-UART module that allows connection with computer to the ESP8266 for programming the flash or for seeing debug messages. There are other two buttons RST (reset) and FLASH, and a micro USB port.
The main Witty board can operate stand-alone, once the firmware is ready to be deployed into a project. The bottom CH340 board can be separated and used as a USB-to-UART stand-alone to program other modules. Witty Cloud module can be programmed with Arduino IDE or with LUA as NodeMCU.
