![]() ![]() Connect the board to your computer using the USB cable. The Mega2560 automatically draw power from either the USB or an external power supply. Upon reconnecting it, I noticed that the micro-controller was extremely hot to the touch, so I disconnected the power again. After a few moments, I noticed a smell and quickly disconnected the power supply. The USB connection with the PC is necessary to program the board and not just to power it up. I recently connected an external power supply (12.3V, 2A) to my Mega 2560 board without any other components connected to it. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog. – 1.0 pinout: added SDA and SCL pins for TWI communication placed near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allows the shields to adapt to the voltage provided from the board, and the second one is an unconnected pin that is reserved for future purposes. Connect your Mega2560 board with an A B USB cable sometimes this cable is called a USB printer cable. The Arduino Mega is a microcontroller board based on the ATmega2560. and Im using 7809 regulator with 12volts 1.3Ah battery. ![]() – ATmega16U2 instead of 8U2 as USB-to-serial converter HI, Im using Arduino Mega 2560 board and with ethernet shield. The Mega 2560 is an update to the Arduino Mega, which it replaces.Īdditional features coming with the R3 version are: They do not map to the left side pwr bus with RESET, 3.3V, 5V, GND, GND. The Mega is compatible with most shields designed for the Arduino Uno, Duemilanove or Diecimila. Im referring to the 2 PWR/GND labeled on the ends of the digital bus/port and the GND pin just above P13 on the Arduino Mega 2560. Tech Specs Compatibility Essentials First Steps Quickstart Guide All you need to know to get started with your new Arduino board. Four serial ports Connect to several devices through the 4x hardware serial ports (UARTs) to your Arduino Mega. 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. The Mega 2560 has 54 digital pins, whereas 15 supports PWM, and 16 analog input pins. 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. You can supply voltage through this pin, or, if supplying voltage via the power jack, access it. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. from the USB connection or other regulated power source). ![]()
