ESP8266 ESP-05 Remote Serial Port WiFi Transceiver Wireless Module

Product Review: 

• The ESP-12 module is one of the most complete of the ESP family as it allows you to use a large number of pins. You can program this module to work stand alone with the Arduino IDE or with LUA as Nodemuc.
• It has improved peripheral circuits, four-layer board technology, enhanced impedance matching, and better signal output.
• Whether it is stability or anti-interference ability, PCB antennas have been tested by professional laboratories and are perfectly matched.
• The enhanced version is fully compatible with the previous firmware.
• This cheap and small Wifi transceiver is the 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.
• The system is equipped with ESP8266 and its features are the energy-saving VoIP can quickly switch between the sleep/wake patterns with low-power operation adaptive radio bias front-end signal processing functions.
• The ESP8266 is a highly integrated chip allowing you to program this module and let it work stand alone with the Arduino IDE or with LUA as Nodemuc.
• The pins are based on ESP-12 and six new IO ports and SPI ports are introduced for easier development and applications.
• Durable, lightweight, low consumption and highly integrated chip.
