Arduino MEGA 2560 R3 (ATMEGA2560-16AU MCU)
Overview
The Arduino Mega 2560 is a microcontroller board based on the ATmega2560 (datasheet). It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila.
ESP8266 ESP-12F WiFi module
The module has the ability to run independent of a host controller.
The ESP8266 Serial/UART to WiFi module is a great way to connect your Arduino or other microcontroller projects to a WiFi network.
You can proceed to create your next internet of things (IOT) project with affordable network connectivity by implementing this module into your design.
The ESP8266 has 3.6V max tolerant I/Os so you will need a logic level converter to connect it with higher voltage devices such as Arduino.
The ESP8266 requires 3.3V power so you may need a 3.3V voltage regulator to provide the correct voltage, depending on your setup.
ESP8266 serial WIFI Module ESP-12E (Upgraded Version)
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.
