The ESP8266/ ESP-12F Module/ Serial WIFI Witty Cloud Development Board + MINI nodeMCU is cheap and small Wifi transceiver, a perfect solution for Home Automation and IoT applications. It can be the replacement for your NRF24L01, it can talk to your Wifi router directly through the UART MCU’s (Rx, Tx).
The ESP-12 module is one of the most complete of the ESP family as it allows you to use the biggest amount of pins. You can program this module to work stand alone with the Arduino IDE or with LUA as NodeMCU. It has an LDR and a WS2812 LED already on board for your projects. The board comes with a CH40 micro USB module to program it.
The ESP8266 is a highly integrated chip, including antenna and power management converter. The system equips ESP8266 and its features are: energy saving VoIP quickly switch between the sleep/wake patterns, with low-power operation adaptive radio bias, front-end signal processing functions.
This ESP8266/ ESP-12F Module/ Serial WIFI Witty Cloud Development Board + MINI nodeMCU is a cloud intelligent hardware development kit, the history of the most simple and most cost-effective IoT development board, don’t need you to understand the knowledge of the network, the TCP/IP another complexes, as long as you will C language, can use EMC’s with cloud SDK quickly realize the secondary development, the DEMO board can use mobile phone flow control panel mount RGB colorful lights, mobile terminal APP, can display environment brightness by photosensitive resistance, less code as long as the modification for half an hour can make your own remote control equipment, system generates free APP (Android, IOS), open the SDK.
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 8-pin headers.
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 a 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 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 can be programmed with Arduino IDE or with LUA as NodeMCU.
Note:User push button connected to GPIO4, Bottom board (with CH340G) can be separated and used as a USB-to-UART stand-alone to program other modules (like ESP-01), Two mini USB connectors (on each on bottom and top boards) to allow top board to be powered and used independently, While this board is fully compatible with the NodeMCU firmware, it does not come pre-flashed with it. Since we don’t open the original packaging, we don’t get a chance to re-flash it before sending it to you. You must reflash it (using the NodeMCU flasher or the Arduino IDE) before you can use it, ESP-12F module with Espressif ESP8266EX SoC, Connectivity – WiFi 802.11 b/g/n, 2x 8-pin headers with GPIOs, VCC, GND, Reset, ADC, and UART, USB – 2x micro USB port (one for power, one for debugging), Photoresistor, RGB LED, three buttons for power, reset and firmware upgrade.
