Provide 8-bit PWM output with the analogWrite() function. See the attachInterrupt() function for details. These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. External Interrupts: 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2).
#Arduino mega pinout serial#
Pins 0 and 1 are also connected to the corresponding pins of the ATmega8U2 USB-to-TTL Serial chip. Used to receive (RX) and transmit (TX) TTL serial data. In addition, some pins have specialized functions: 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. Input and OutputĮach of the 50 digital pins on the MEGA ADK can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions.

The MEGA ADK has 256 KB of flash memory for storing code (of which 8 KB is used for the bootloader), 8 KB of SRAM and 4 KB of EEPROM (which can be read and written with the EEPROM library). A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs for working with the 5V or 3.3V. This pin on the Arduino board provides the voltage reference with which the microcontroller operates. A 3.3 volt supply generated by the on-board regulator. Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). This pin outputs a regulated 5V from the regulator on the board. You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). If using more than 12V, the voltage regulator may overheat and damage the board. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. The board can operate on an external supply of 5.5 to 16 volts. A power supply must be capable of providing 1.5A to use this much current. An additional 750mA is allocated for any actuators and sensors attached to the board. 750mA is available for the phone and MEGA ADK board. When the ADK is powered over USB, 500mA total is available for the phone and board.The external power regulator can supply up to 1500mA. NB: Because the MEGA ADK is a USB Host, the phone will attempt to draw power from it when it needs to charge. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector. The adapter can be connected by plugging a 2.1mm center-positive plug into the board's power jack. The power source is selected automatically.Įxternal (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The Arduino MEGA ADK can be powered via the USB connection or with an external power supply.

The second one is a not connected pin, that is reserved for future purposes.įor information on using the board with the Android OS, see: In future, shields will be compatible both with the board that use the AVR, which operate with 5V and with the Arduino Due that operate with 3.3V. 1.0 pinout: added SDA and SCL pins that are 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.Revision 3 of the board has the following new features:
Revision 2 of the Mega ADK board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode. Similar to the Mega 2560 and Uno, it features an ATmega8U2 programmed as a USB-to-serial converter. It has 54 digital input/output pins (of which 15 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. It has a USB host interface to connect with Android based phones, based on the MAX3421e IC. The Arduino MEGA ADK is a microcontroller board based on the ATmega2560.
