Arduino MEGA 2560 With CH340G

The Mega 2560 R3 is an Arduino-compatible board that uses the CH340 USB device for the lowest cost. The Mega 2560 R3 provides a large amount of I/O and memory and is ideal for larger projects KEY FEATURES OF MEGA 2560 R3 WITH CH340 USB: • 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 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 very 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. If you don’t want to worry about drivers, select our Mega 2560 R3 board with ATmega16U2 USB.
