![]() ![]() ![]() Therefore, mark like 'use for analog ground' in not needed. 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. The Arduino Mega 2560 Rev3 is a microcontroller board that is based on the ATmega2560 microcontroller. 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. The Customer must not REGARDING PRODUCTS, INCLUDING BUT NOT LIMITED TO, ANY IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Blue is for differences due to added functionality (extra pins). Arduino may make changes to specifications and product descriptions at any time, without notice. With 54 digital I/O pins, 16 analog inputs and a larger space for your sketch it is the recommended board for 3D printers and robotics projects. ![]() In general, this means that the UNO put several functions on one pin and these have moved to separate pins on the Mega. The Arduino MEGA 2560 is designed for projects that require more I/O lines, more sketch memory and more RAM. It works well, but if I use LCD display, the power consumption is high, and the notebooks USB supply is not enough for this - or the Hi, Guys Im a very new Arduino user. Red are differences, where the functionality has moved on Mega2560 compared to UNO. I ordered from Chine a WavGAT MEGA 2560 clone. Green have the same function and position as the Arduino UNO R3. See the graphic below for a (dare I say) mega-map of the Mega’s pins. Inspired by Nick's UNO pinout I did a similar one for the Arduino Mega2560 R3.Īnnotations are color coded. ![]()
