RX is the receiver part of this communication system, it can then output normally if you are not. The Arduino Mega 2560 is a fantastic option for use in prototyping with ease, especially for 3D printers and robotics, where the Uno just doesn’t hold up. EdsArduino: You would be able to use pin 1 as a GPIO pin, however you cannot use pin 0 as a GPIO, this is because the arguing has TX/RX pins that are used to program the Arduino and connect to some external modules. The Mega’s shield selection includes any shield compatible with the Arduino Duemilanove and Diecimila.

Using a shield gives your Mega board display options, Wi-Fi connectivity or even video game emulation software with relative ease. If you take a look at the headers on the Mega, youll notice that one of them has labels of 'RX1' and 'TX1' through 'RX3' and 'TX3'. These preassembled PCBs interface directly into the Mega’s headers and give the board incredible capabilities in a condensed package. With it, anyone can add to or use the massive selection of codes to provide easy access to a world of programming possibilities.Īnother prominent feature of all Arduino boards, including the Mega, are the Arduino shields. The open-source coding terminal has a variety of features that make it accessible to both novices and programming gurus alike, most notably the IDE’s associated library of projects and other syntaxes created by the massive community of Arduino users. Like the Uno, the Mega operates in the Arduino Integrated Development Environment (IDE). Arduino Mega 2560 Pinout DiagramĪs far as other hardware on the Mega goes, it also touts four serial ports for general attachments, a USB connection (with a dedicated ATmega16U2 processor for interfacing with your computer), a reset button and a power supply port. See the graphic below for a (dare I say) mega-map of the Mega’s pins. That’s where the Arduino Mega pinout diagram comes in handy.

With so many pins and features, it can be overwhelming to understand how to use them all.

Because of its brawnier processor, the Mega has 54 digital I/O pins (15 of which can provide PWM output) and 16 analog pins, which is almost four times that of its little brother, the Uno. It has 54 digital input/output pins, 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. This is partly the same protocol as RS232, but it uses TTL logic levels (in this case the levels 5V and 0V), while RS232 has different voltage levels and more lines (like control lines). Thanks to the ATmega2560 (and its associated crystal oscillator), the Arduino Mega sports 16 MHz clocking speed, as well as 256 KB of flash, 8 KB of SRAM and 4 KB of EEPROM. The Arduino speaks UART (Universal Asynchronous Receiver Transmitter) with it's Serial interfaces (there are 4 of these on the Mega).

As stated before, the brain behind the Arduino Mega is the ATmega2560.
