Arduino MEGA 2560 Rev.3 CH340 (compatible) is a board 100% compatible with the Arduino IDE environment, based on the same open hardware schemes, but cheaper.
The version with the CH340 communications chip is a bit cheaper, but requires the installation of a specific driver ( download driver CH340 * (click here) ).
We also have available the original MEGA 2560and the MEGA 2560 compatible with 16U2 communications chip that do not require the installation of a specific driver.
Arduino MEGA 2560 has more memory for the program, more RAM and more pins, while maintaining compatibility with the UNO or Duemilanove version.
In this new version, a powerful ATMEGA2560 AVR processor with ample memory space is used to program and run at 16Mhz. It is ideal for advanced electronics and robotics projects, standing out for its high number of input and output pins and its 4 hardware UART ports .
The Shield plates of the Duemilanove / UNO version are still compatible with this model since the basic pins are located in the same place, so we can continue using any shield plate of the Duemilanove model. The only difference is that the Mega board is slightly longer, so we can access a new row of pins with additional IO pins.
This board is a revolution for the world of robotics or projects with large memory and I / O needs.
