This board is a compatible version of the latest iteration of the Arduino MEGA 2560 R3, which is one of the more popular of the development boards available for hobbyists due to its large amount of I/O. It is the logical upgrade to the Arduino Uno when that device runs out of I/O or memory space.
- MEGA 2560 R3 (Arduino compatible) board
- 21″ long USB cable
Key Features of MEGA 2560 R3:
- ATmega2560 processor running at 16MHz
- CH340 Serial to USB converter
- 256KB Flash memory
- 54 Digital I/O
- 15 PWM shared with the digital I/O
- 16 Analog inputs that can also be used as digital I/O for a total of up to 70 digital I/O
- 4 Hardware serial ports
- 5V Operation
The MEGA 2560 operates at 5V which can be supplied via an external power supply or through the USB port connection. The power source is selected automatically if both are available. If an external supply is used, it is recommended to use a supply between 7-12V. Higher input voltages will cause the on-board regulator to work harder and may cause it to overheat. Our 7.5V AC adapter works extremely well for powering these boards.
The board ships with a 21″ long USB cable and can be programmed using the Arduino IDE via the USB port.
The attached MEGA 2560 board pin-out shows the most commonly used functions for the pins, but some pins can support other functions. Refer the the Arduino documentation for all possible functions for the pins.
Our Evaluation Results:
These are nice compatible assemblies with good build quality.
The board uses the CH340 chip for USB communications. If you have any issues with connecting to the board, you may need to download a driver. 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.
Before they are shipped, these modules are:
- Powered up and the example program ‘Blinky’ which blinks the on-board LED once per second is downloaded to verify basic operation.
- Repackaged in high quality resealable ESD bag for safe storage.
