Where are the pins on the Arduino Mega 2560?

Revision 3 of the Arduino board and the current Genuino Mega 2560 have the following improved features: 1.0 pinout: SDA and SCL pins – near to the AREF pin – and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board.

Where can I find an Arduino Pinout diagram?

Last year I found some awesome Arduino pinout diagrams with full colour on the Arduino forums. They are all titled something like The Unofficial Arduino Pinout Diagram / The Definitive Arduino Pinout Diagram, etc. They disappeared from the Internet (pighixxx.com) in December 2013.

How many pins are in an Arduino ATmega328 microcontroller?

The ATMEGA328 in the Arduino UNO microcontroller development board is as shown in the following figure: ATMEGA 328 microcontroller is an eight bit microcontroller based on the RISC (Reduced Instruction Set Computing) architecture. It has total 28 pins out of which some are GPIO (General Purpose Input / Output) pins and some are power pins.

How many pins does an Arduino board have?

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.

Is the Arduino Mega 2560 compatible with the Uno?

The Mega 2560 is designed to be compatible with most shields designed for the Uno and the older Diecimila or Duemilanove Arduino boards. Digital pins 0 to 13 (and the adjacent AREF and GND pins), analog inputs 0 to 5, the power header, and ICSP header are all in equivalent locations.

Where are the SPI pins on an Arduino?

The SPI pins are also broken out on the ICSP header, which is physically compatible with the Arduino /Genuino Uno and the old Duemilanove and Diecimila Arduino boards. LED: 13. There is a built-in LED connected to digital pin 13. When the pin is HIGH value, the LED is on, when the pin is LOW, it’s off. TWI: 20 (SDA) and 21 (SCL).
