The ESP8266/ ESP-12F Module/ Serial WIFI Witty Cloud Development Board + MINI nodeMCU is a 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 MCUs (Rx, Tx).
The upper board is the main board 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 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.
It has an LDR and a WS2812 LED already on board for your projects. The esp board comes with a CH40 micro USB module to program it. 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, and front-end signal processing functions.
