4/16/2024 0 Comments Arduino mega 2560 pinout table![]() All analog pins of this board can be used as digital I/O pins. Every pin of this board comes by a particular function which is allied with it. The pin configuration of this Arduino mega 2560 board is shown below. The USB host chip used in this is MAX3421E.The electrically erasable programmable read-only memory (EEPROM) is 4 KB.The static random access memory (SRAM) is 8 KB.Flash Memory like 256 KB where 8 KB of flash memory is used with the help of bootloader. ![]() DC Current for each input/output pin is 40 mA.The digital input/output pins are 54 where 15 of these pins will supply PWM o/p.The input voltage will range from 6volts to 20volts.The recommended Input Voltage will range from 7volts to 12volts.The operating voltage of this microcontroller is 5volts.The specifications of Arduino Mega include the following. These boards work with every existing shield although can adjust to latest shields which utilize these extra pins. Another pin is not associated & it is kept for upcoming purposes. ![]() One pin is the IOREF that permit the shields to adjust the voltage offered from the Arduino board. Additionally, there are two latest pins located near the RST pin. The SCL & SDA pins of Mega 2560 R3 board connects to beside the AREF pin. This board can be protected from the unexpected electrical discharge by placing a base plate. So, the power supply of this board can be done by connecting it to a PC using a USB cable, or battery or an AC-DC adapter. This board mainly includes everything which is essential for supporting the microcontroller. It includes digital input/output pins-54, where 16 pins are analog inputs, 14 are used like PWM outputs hardware serial ports ( UARTs) – 4, a crystal oscillator-16 MHz, an ICSP header, a power jack, a USB connection, as well as an RST button. An application that does not require a strong CPU but needs plenty of GPIO will do well with the Mega.Īnalog projects can be done with all the Arduino boards, but the Due stands out with 12 analog inputs and 2 analog outputs.The microcontroller board like “Arduino Mega” depends on the ATmega2560 microcontroller. If a project requires plenty of GPIO, the Due and Mega are the obvious choices. The UNO and Nano use the same processor which means that in terms of hardware and peripherals the UNO and Nano are identical. While the Mega is a large Arduino with plenty of GPIO, its CPU speed is still the same as that found on the UNO and Nano (same Mega family) and so there is no speed advantage to using the Mega. If a project requires high processing power, the Due comes out on top with its powerful ARM core and large RAM/ROM. The Mega and Due are much larger boards which makes them difficult to use in space restricted applications. The UNO is a medium sized development board but is still small enough to be mounted to many projects including remote-controlled devices such as RC cars and boats. When it comes to physical dimensions the Arduino Nano is the smallest and is a very portable device. When looking at hardware the following should be considered: While the cost aspect of each Arduino is obvious (the lowest cost option is always the preference), the hardware may not be so easy to determine. The deciding factor each project will use comes down to two basic things: hardware and cost. This means that you are unlikely to fall into device-specific traps that could prevent a piece of code from working because of hardware configurations or inherent bugs.Īrduino code can be easily transferred to different boards with virtually no changes which is highly beneficial to any designers wanting to change their mind about what board their project will use. Now that we looked at some of the details about each board, optimal uses of each board can be determined.Īlthough the UNO is the most popular board, all boards have excellent support through online forums thanks to the common architecture and the use of a common language and IDE.
