2/8/2024 0 Comments Arduino mega 2560 reset pin![]() ![]() They are circled on the photo below, and marked GND on the board. The Mega 2560 R3 works with all existing shields but can adapt to new shields which use these additional pins. On your Mega2560 are 5 ground pins (effectively equivalent because they are connected). The other is a not connected and is reserved for future purposes. One is the IOREF that allow the shields to adapt to the voltage provided from the board. DC supply can be given via power jack or by using USB cable port. ![]() 5 volt supply can also be generated and regulated on board. 3 voltage supply can be generated with the help of on board regulator and the maximum current is 50 mA that can pass through it. In addition, there are two new pins placed near the RESET pin. Arduino Mega 2560 can have power supply of two voltages i.e. The Mega 2560 R3 also adds SDA and SCL pins next to the AREF. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila. It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 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. The Arduino Mega is a microcontroller board based on the ATmega2560. As the title suggest the Arduino Mega 2560 R3 Italy Genuine is the Genuine/ Original Board made from Italy, and not a clone which are usually made in China, though it is more expensive compared to the clones, the board is more robust and will last longer compared to a clone. ![]()
