#PINOUT ARDUINO MEGA SERIAL#

See the attachInterrupt() function for details. 0 pinout: added SDA and SCL pins that are near to the AREF pin Stronger RESET circuit. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. 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.

#PINOUT ARDUINO MEGA SERIAL#

Pins 0 and 1 are also connected to the corresponding pins of the ATmega16U2 USB-to-TTL Serial chip.Įxternal Interrupts: 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2). Used to receive (RX) and transmit (TX) TTL serial data.

5V: Output pin from the voltage regulator on the board with an output of 5 volts and a maximum current of 800 mA. (hardware serial ports), a USB connection, a power jack, an ICSP header, and a reset. Via the pin, you can consume voltage when the device is powered via the external power connector. The board contains 54 digital input/output pins, 16 analog inputs, 4 UARTs. In addition, some pins have specialized functions: VIN: Input pin for external power supply with a voltage range from 7 to 12 volts. connection, a power jack, an ICSP header, and a reset button. 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. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. Each of the 54 digital pins on the Arduino 2560 Mega can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions.
