You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header using Arduino ISP or similar see these instructions for details. It communicates using the original STK500 protocol ( reference, C header files). The ATmega2560 on the Mega 2560 comes preprogrammed with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. For details, see the reference and tutorials. The Mega 2560 board can be programmed with the Arduino Software (IDE). Arduino_Mega2560_Rev3 schematic PDF file. The excellent after-sales service and professional technical support will ensure you have a good time with Osoyoo Mega2560 Board Tech Spec MicrocontrollerĪrduino Mega2560 is open-source hardware! You can build your own board using the following files from the Arduino official site: We strictly control the quality of the products before leaving the factory. This is perfectly legal, seeing that the whole Arduino ecosystem is open source! Please note this board is manufactred by Osoyoo! We do have control of the brand and quality of components used! We have also carefully selected suppliers that consistently supply quality products. None of the Arduino Mega2560 R3 boards sold on the internet at this price are original, they are all copies. It is NOT an original Arduino board, but is similar. The Mega 2560 board is compatible with most shields designed for the Uno and the former boards Duemilanove or Diecimila. It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. 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. The Osoyoo Mega2560 Board is fully compatible with Arduino Mega2560 rev.3, it is a microcontroller board based on the ATmega2560. This gives your projects plenty of room and opportunities.” - Overview 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. That means that if you install MegaCore via Boards Manager, or have an old manually installed version, you will only be able to use the extra pins with Tools > Pinout > AVR pinout selected (and note that pinout has different pin mapping than what is marked on the Mega's silkscreen.“The MEGA 2560 is designed for more complex projects. Yes, you could modify the variant file, but this work has already been done for us by MCUdude in their excellent MegaCore, so it's much better to not duplicate work that is already I should have mentioned that, although the work has been done to support all pins of the ATmega2560 in both the pinout options for the ATmega2560, this work for the "Arduino MEGA pinout" was done after the time of the last MegaCore release. If you want to use extra pins, you can rewrite the Arduino header file, add the extra pins to be used in the Arduino header file, and ensure that they do not conflict with the original used pins. The compiler in this case is avr-gcc, though each hardware package can use its own compiler tool. The default compiler* (that is, the Arduino IDE)
