It is not recommended to power the device through the 5V pin – you risk burning the board. 5V: Output pin from the voltage regulator on the board with an output of 5 volts and a maximum current of 800 mA.Via the pin, you can consume voltage when the device is powered via the external power connector. VIN: Input pin for external power supply with a voltage range from 7 to 12 volts.It’s an ICSP-connector for internal microcontroller programming ATmega16U2.
SPI lines are output on a 6-pin connector, as well as duplicated on digital pins 50 (MISO), 51 (MOSI), 52 (SCK), and 53 (SS). Also, using the SPI library, these outputs can communicate with the expansion boards on the SPI interface. ICSP-connector is designed for in-circuit programming microcontroller ATmega2560. It’s a linear voltage regulator LP2985-33DBVR with 3.3-volt output. Linear voltage regulator LD1117S50CTR with 5-volt output provides power for microcontrollers ATmega2560, ATmega16U2, and other platform logic. It’s an analog of the RESET button on a regular computer. It’s a connector for an external power supply from 7V to 12V. Type-B USB connector for power and firmware of the Arduino Mega 2560 platform using a computer. At high level, the LED turns on, at low level, the LED turns off. User LED connected to the 13 pin microcontroller. LED Nameįlash when exchanging data between Arduino Mega 2560 and PC. When connected to a PC, the Arduino Mega 2560 is defined as a virtual COM port. Microcontroller ATmega16U2 provides a connection of microcontroller ATmega2560 with the USB port of the computer. It should be noted that with a power supply voltage of 7-20 volts, the board works perfectly, and with a smaller, for example, 5 volts, there may be situations with the unstable operation. The controller provides 256KB of Flash memory for storing firmware, 8KB of SRAM, and 4KB of non-volatile EEPROM memory for data storage. The heart of the Arduino Mega platform is an 8-bit AVR family microcontroller – ATmega2560 with 16 MHz clock speed. To launch the platform, download and install the Arduino IDE integrated development environment on your computer.
