Step 2: Burn the bootloader in Arduino IDE
Example: Using an UNO to program a Nano (digital and power pins). When the boards are connected, you can proceed with burning the bootloader in Arduino IDE. Option A: Using the digital and power pinsįor each row in the table below, connect the programmer pin to the corresponding target pin. In this case, change the line #define RESET 10 to use a different pin. On some boards PIN 10 may not be available. Check the pinout diagrams in Arduino Docs to find which pins to use for CIPO, COPI, and SCK. Note: Although the “Arduino as ISP” only works for programming targets of the AVR architecture, you can use boards of any architecture as an “Arduino as ISP” programmer. You’ll need female-to-female jumper cables for these pins. CIPO, COPI, and SCK are available in a consistent physical location on the ICSP header. These are the most commonly used pins on Arduino, and you’ll only need six standard male-to-male jumper wires. On many boards (including UNO, Mega, and Nano), these are available in two locations: The easiest way to burn the bootloader to classic AVR boards (UNO, Mega, Nano, etc.) is using a second Arduino board as a programmer, which is the method that will be covered below.ĪVR boards are programmed with the SPI interface (COPI, CIPO and SCK signals). Whether the bootloader has been corrupted or intentionally has been removed, it can be restored by burning (also called, flashing or programming) a new bootloader to the board. It comes preprogrammed on the microcontrollers on Arduino boards.

The voltage regulator allows to use up to 18V as an input value, however we do not recommend exceeding the recommended values aforementioned, since this can lead to excessive heat and damage the device.The bootloader is a small piece of software that allows uploading of sketches onto the Arduino board.
The maximum output current for 5V is around 800mA, while for 3.3V it is about 800mA. The used voltage regulator operates in a range of 6 to 9V DC. The board can be powered directly through the Micro USB connector, or via the corresponding contact on the board (Vin).

The board has a Micro USB connector that allows you to connect the microcontroller to the computer via the USB-UART adapter CH340(A driver installation may be required).Ĭonnectivity to the computer is provided through the common micro USB connector (universally used by most phones, including Android smartphones). It uses the original chip, and a 16 MHz high-quality quartz resonators is present on the board. Even though it is an Embed board, it is solid stable as the Mega Board.

The Mega Pro Embed functionalities are identical to the Arduino Mega 2560. It has a compact form factor of 38 x 54mm and is an excellent solution for developing projects based on ATmega2560. This board is compatible with the Arduino Mega 2560. The boards might look slightly different than in the pictures. Please Note: This is a generic board, and can be manufactured by a variety of different manufacturers. It is assembled with a genuine Atmel ATmega2560 microcontroller and the low cost CH340G USB-UART interface. This is a low cost and miniature version of the popular Arduino Mega 2560.
