The ESP8266 Serial WIFI Witty Cloud Development Board + MINI node MCU is designed as a cheap and small Wi-Fi transceiver. It is an ideal solution for Home Automation and IoT applications. It is said to be the perfect replacement for NRF24L01 so that it can talk to your Wifi router directly through the UART MCU’s (Rx, Tx).
The Latest ESP-12F ESP8266 Wifi Module AP & Station Remote Serial Wireless IoT Board was designed based on an integrated chip specifically to fulfil the needs of a new connected world. It can handle all the necessary overhead for communicating with your network, such as TCP/IP stack and communicating with your 802.11 networks. It is possible to program this module to operate stand-alone with the For Arduino IDE or with LUA as NodeMCU. This development board comes with an onboard LDR and a WS2812 LED for your projects. In addition, the board comes with a CH40 micro USB module to program it.
The ESP8266 designed as a highly integrated chip consists of an antenna and power management converter. This system equipped with ESP8266 featuring energy-saving VoIP quickly switch between the sleep/wake patterns. Thereby offers low-power operation adaptive radio bias, front-end signal processing functions.
This “Witty Cloud”, the ESP8266 Serial Wi-Fi Witty Cloud Development Board ESP-12F Module. These are designed as a compact ESP8266-based module made by stacking two PCB boards connected by a pair of 8-pin headers. The upper board is designed as the mainboard which consists of an ESP-12F module – where the 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. It allows connection with a computer to the ESP8266 for programming the flash or for seeing debug messages. In addition, there exist 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 for your project. The bottom CH340 board can be separated and used as a USB-to-UART stand-alone to program other modules. Witty Cloud module programmed with Arduino IDE or with LUA as NodeMCU.
