Preprogrammed with a bootloader, the ATmega2560 allows the uploading of a new code without the need for an external hardware programmer. Mega 2560 board is programmable with Arduino’s IDE, CLI, and Web Editor. It has a flash memory of 256KB, with the bootloader occupying 8KB, 8KB SRAM, and 4KB of EEPROM, readable and writable with the EEPROM library. The board also features ATmega16U2 USB serial processor as interface between the USB input signals and the main processor. It features a numerous of input and output lines for interfacing many external devices. The main processor ATmega2560 chip operates at 16MHz, which is easily replaceable since it is not soldered. Mega 2560 is also compatible with most Uno shield designs and older boards, Diecimila or Duemilanove Arduino. Compared to the even multiple of the 100 mil spacing of most pins, digital pins 7 and 8 are 160 mils (0.16’’) apart. The board has three screw holes for attaching it to surfaces or cases. The PCB of Mega 2560 spans 4 x 2.1 inches, with the power jack and USB connector a little over the said measurement. The Mega 2560 board contains all the necessary things to support the microcontroller when connected to a power source. Arduino Mega 2560 likewise includes a USB connection, an ICSP header, a power jack, a reset button, and a 16MHz crystal oscillator. It has 54 digital IO pins, 15 of which can be set as PWM outputs, 16 analog inputs, and 4 UARTs hardware serial ports-a much larger set of IOs compared to a traditional Uno board, given their form factors. In addition to flexibility, the amount of contributing developers makes it easy to find and fix flaws.īuilt on ATmega2560, Arduino Mega 2560 suits applications, and projects requiring a huge number of IO pins for high processing power. Numerous developers from all around the world supply these license-free codes that are not only available but also flexible enough, allowing users to modify them for the desired function. But microcontroller hardware and software now see a better route-thanks to open-source software. The production of specialized microcontrollers for unique devices is time and money inefficient. It is integrated into a system and manages a single function by deciphering data received and taking appropriate actions. Despite being tiny computers built into a single chip, they have programmable input/output peripherals, memory, and a processing core. Therefore, mark like 'use for analog ground' in not needed.Microcontrollers have the power to control a wide variety of machines, including life-support systems, spacecraft, aircraft, and even mobile phones. Update: correct SCL to SCK, correct colors, call out second ICSP headerĪs per diagra of Arduino Mega 2560 Reference Design diagram:Īs per Arduino Mega 2560 Reference Design:īy continuity measurement, I have found that all connector pins labelled as 'GND' are shorted together this means that the AGND and DGND pins of ATmega2560 are shorted together at the connectors. I find it convenient to use the GND pins near to the analog input pins as analog grounds, and to use the GND on the end block for digital grounds, when linking to external circuitry. Blue is for differences due to added functionality (extra pins). In general, this means that the UNO put several functions on one pin and these have moved to separate pins on the Mega. Red are differences, where the functionality has moved on Mega2560 compared to UNO. Green have the same function and position as the Arduino UNO R3. Inspired by Nick's UNO pinout I did a similar one for the Arduino Mega2560 R3.Īnnotations are color coded.
