Before you load a new program on the Arduino IDE, you must know what IC is on your board. The main IC (integrated circuit) on the Arduino is slightly different from the panel pair. You can regard it as the brain of your board. When connecting to PC, program the firmware to ATMEGA2560-16AU.Įach Arduino board has its own microcontroller. In fact, slave the output devices to the SPI bus host. It is often called the SPI (serial peripheral interface) and can be considered an "extension" of the output. The AVR, an Arduino micro-program header consisting of MOSI, MISO, SCK, RESET, VCC, and GND. You can reset your Arduino board, for example, start the program from the initial status. Onboard has 16 analog inputs, labeled A0 to A15. You can supply an external power input DC7-12V through this pin to Arduino board. The function is the same as reset button. 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.Ĭonnect an external button to reset the board.

This pin on the board provides the voltage reference with which the microcontroller operates. Output DC 5V, the drive current is 2A.Īrduino board can be supplied with an external power DC7-12V from the DC power jack. It tells us that the frequency is 16,000,000 Hertz or 16MHz.Ĭonvert an external input DC7-12V voltage into DC 5V, then switch DC 5V to the processor and other components. The number printed on the top of the Arduino crystal is 16.000H9H. How does Arduino calculate time? by using a crystal oscillator.

When Arduino board communicates via serial port, receive the message, RX led flashes. Onboard you can find the label: RX(receive ) When Arduino board communicates via serial port, send the message, TX led flashes. Onboard you can find the label: TX (transmit) USB to serial chip, can convert the USB signal into serial port signal. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off. There is a built-in LED driven by digital pin 13.

When connecting to PC, program the firmware to ATMEGA16U2-MU.Īrduino board can be powered via USB connector.Īll you needed to do is connecting the USB port to PC using a USB cable. ICSP (In-Circuit Serial Programming) Header the value used as the top of the input range). Used with analogReference().Ĭonfigures the reference voltage used for analog input (i.e. Reference voltage (0-5V) for analog inputs. Using pinMode(), digitalWrite(), and digitalRead() functions. Or used as digital output pin to drive different modules like LED, relay, etc. These pins can be configured as digital input pin to read the logic value (0 or 1). Here is an explanation of what every element and interface of the board does:Īrduino MEGA has 54 digital input/output pins (of which 15 can be used as PWM outputs). Keyestudio MEGA 2560 compatible board Advanced: Keyestudio MEGA 2560 compatible board Advanced This gives your projects plenty of room and opportunities. With 54 digital I/O pins, 16 analog inputs and a larger space for your sketch, it is the recommended board for 3D printers and robotics projects. The MEGA 2560 is designed for more complex projects. When connect the external power, output 5V, the drive current can be 2A. However, keyestudio MEGA 2560 compatible board Advanced features the voltage-regulator chip MP2307DN. When connect the external power, output 5V, the drive current is 1A. The voltage regulator chip used in keyestudio MEGA 2560 R3 board is NSP1117. Note: the most important difference between keyestudio MEGA 2560 compatible board Advanced and keyestudio MEGA 2560 R3 board is the voltage regulator chip used in the board. Just simply connect it to a computer with a USB cable or power it via an external DC power jack (DC 7-12V) or via female headers Vin /GND (DC 7-12V) to get started.

With its bootloader, program can be downloaded directly with USB and you don’t need to use other external programmer. It contains everything needed to support the microcontroller. 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, 2 ICSP headers, and a reset button. Keyestudio Mega 2560 compatible Advanced is a microcontroller board based on the ATMEGA2560-16AU, fully compatible with Keyestudio Mega 2560 R3 board and ARDUINO MEGA 2560 REV3.
