Mega2560 R3 Driver ATmega2560-16AU USB Motherboard for Chip Development Educational Motherboard Replacement Programming Feature: 1. Compatibility: Mega2560 R3 solves compatibility and instability issues with traditional 2560 board in WIN7 and Win8 systems . 2. Upgraded USB Chip: Mega2560 R3 replaces the 16 u2 ATMEGA8U2 or ATMEGA16U2 USB chip, which greatly reduces the cost while ensuring excellent application performance. 3. Increased ISP Flash Capacity: With the new ATMEGA16U2 chip, the Mega2560 R3 can offer increased ISP flash capacity, making it easier to expand its functionality and support more advanced programming needs. 4. Versatile USB Interface: The ATMEGA16U2 chip not only offers traditional USB-to-Serial port functionality, but also enables users to customize additional functions such as configuring the USB port such as mice, keyboards, gamepads, cameras, etc. 5. Improved circuitry reset oacute;d: With the release 2011, the Mega2560 R3 reset circuit has been improved to provide better stability and prevent unexpected resets. Additionally, it comes with additional external interfaces such as SDA, SCL and IOREF which can be used for voltage stabilizers and shield compatibility. Specification: Origin: Mainland China Product Options: Without Cable, With Cable (Optional) Product Chip: CH340G Operating Voltage: 5V Input Voltage: 7-12V Recommended, Limited to 6-20V Digital I/O Pins: 54 (of which 15 provide PWM output) Analog input pin: 16 DC current of each I/O pin: 40 MA DC current 3.3V pin: 50 MA Flash memory: 256KB, of which 8KB is used by the bootloader SRAM: 8KBEEPROM: 4KB Clock speed: 16MHZ Size: about 101.2x53.3mm/3.98x2, 09 inch (measured by hand) Weight: 36.6g (measured by hand) Usage method: Plug in the 2560 development board and the driver will be automatically installed Select the MEGA2560 board in the die Select the serial port which can be checked on my computer. Only now, port on your 2560 development board First select the routine that comes with the Ard and burn it The Mega power supply system has two options: direct USB power supply or external power supply. The power supply selection will automatically switch. External power can choose from AC to DC adapter or battery. The limit voltage range of this control board is 6V~12V. However, if the supplied voltage is less than 6V, the I/O port may not be able to provide 5V, causing instability; If the applied voltage is greater than 12V, the voltage regulator may experience overheat protection and more likely damage the MEGA. Therefore, the recommended operating power supply is 6.5-12V, and the recommended power supply is 7V or 12V. Note: Due to the different monitor and light effect, the actual color of the item may be slightly different from the color shown in the pictures. Thank you!
