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. 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. La principale caractéristique de ce microcontrôleur est le nombre accru de ports d’entrée/sortie numériques et analogiques et de ports UART pour la communication avec les modules. La disposition des ports sur la carte Arduino Mega ATmega2560 Rev3 est illustrée dans l’image ci-dessus.
Red are differences, where the functionality has moved on Mega2560 compared to UNO. Brochage de l’Arduino Mega 2560 / pinout Mega. Green have the same function and position as the Arduino UNO R3. In the following picture, you’ll see the pinout diagram of Arduino Mega 2560 Rev3.
Inspired by Nick's UNO pinout I did a similar one for the Arduino Mega2560 R3.Īnnotations are color coded. Is there any difference in hardware pin for arduino mega 2560 and mega 2560 R3 in interfacing TFT Please let us know.
