![]() 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 Mega2560 Pro Mini board has all the IOs of Arduino Mega2560 R3, following are the parameters. 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. It has the same ATmega2560 processor and pinout, but also. RAMPS 1.4: This board is designed for use with 3D printers and is based on the Arduino Mega 2560 Rev3. It has the same ATmega2560 processor and pinout as the Mega ADK. Red are differences, where the functionality has moved on Mega2560 compared to UNO. Seeeduino Mega: This board is a shrunk version of the Arduino Mega 2560 Rev3 and is manufactured by Seeed Studio. Green have the same function and position as the Arduino UNO R3. ![]() 0 pinout: added SDA and SCL pins that are near to the AREF pin Stronger RESET circuit. ![]() The same connection could be made to the ICSP of the UNO following the pinout explained in the page. The Mega is 100 compatible with Arduino IDE and most of the shields are designed for the Arduino mega2560 R3RoHS Compliant The chip is Atmega2560-16au and Atmega16u2, the same as the official version. Inspired by Nick's UNO pinout I did a similar one for the Arduino Mega2560 R3.Īnnotations are color coded. The Arduino MEGA above is programming an Arduino UNO connecting D51-D11, D50-D12, D52-D13, GND-GND, 5V-5V and D10 to RESET. ![]()
