![]() ![]() Revision 3 of the board has the following new features: Revision 2 of the Mega2560 board has a resistor pulling the 8U2 HWB line to ground, making it easier to put into DFU mode. Instead, it features the ATmega16U2 ( ATmega8U2 in the revision 1 and revision 2 boards) programmed as a USB-to-serial converter. The Mega2560 differs from all preceding boards in that it does not use the FTDI USB-to-serial driver chip. 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 6 to 20 volts. ![]() 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 can be powered via the USB connection or with an external power supply. Pin Mapping: PinMap2560 page Summary Microcontroller Schematic: arduino-mega2560_R3-schematic.pdf Schematic, Reference Design & Pin MappingĮAGLE files: arduino-mega2560_R3-reference-design.zip The Mega 2560 is an update to the Arduino Mega, which it replaces. The Mega is compatible with most shields designed for the Arduino 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 14 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. Repackaged in high quality resealable ESD bag for safe storage.Īnalog Input Pins (can also be used as digital I/O)ĭC Current which can be drawn from 3.The Arduino Mega 2560 is a microcontroller board based on the ATmega2560 ( datasheet).Powered up and the example program ‘Blinky’ which blinks the on-board LED once per second is downloaded to verify basic operation.Before they are shipped, these modules are: If you don’t want to worry about drivers, select our Mega 2560 R3 board with ATmega16U2 USB. Just search for Arduino CH340 driver and you will find a number of sources for drivers depending on what Windows or Mac operating system you are using. If you have any issues with connecting to the board, you may need to download a driver. The board uses the CH340 chip for USB communications. These are nice compatible assemblies with very good build quality. Refer the the Arduino documentation for all possible functions for the pins. The attached Mega 2560 board pin-out shows the most commonly used functions for the pins, but some pins can support other functions. Our 7.5V AC adapter works extremely well for powering these boards. Higher input voltages will cause the on-board regulator to work harder and may cause it to overheat. If an external supply is used, it is recommended to use a supply between 7-12V. The power source is selected automatically if both are available. The Mega 2560 operates at 5V which can be supplied via an external power supply or through the USB port connection. 16 Analog inputs that can also be used as digital I/O for a total of up to 70 digital I/O.Key Features of MEGA 2560 R3 with CH340 USB: Mega 2560 R3 with CH340 USB (Arduino Mega 2560 R3 compatible).The Mega 2560 R3 provides a large amount of I/O and memory and is ideal for larger projects Package Includes: The Mega 2560 R3 is an Arduino compatible board that uses the CH340 USB device for the lowest cost. ![]()
