Electronic module USB development board MCU MEGA2560-16AU MEGA2560 R3 ATMEGA16U2
MEGA2560 2012 R3 version is the controller version, and the difference between MEGA2560 2012 and 2011 is as follows:
1. Replace the 2011 version of 8U2 with 16U2 chip, and the capacity of ISP FLASH will be doubled to facilitate more powerful function expansion and development needs. In addition to the traditional USB serial port function, the 16U2 allows users to program and define other functions, such as configuring the USB port as a mouse, keyboard, game joystick, camera, etc
2. SDA and SCL (located on the left side of AREF) are added to the external interface based on the 2011 version. The interface can provide a voltage reference. A port is reserved on the left side for the compatibility of future series products.
3. The circuit is improved compared with the 2011 version. Prevent accidental reset and make the circuit more stable.
