Board length 101.8MM*width 53.4MM*thickness 1.6MM)
The MEGA25602012R3 version is the version of the MEGA series ad controller, and the 2011 version
The difference is as follows:
1. Replace the 2011 version of ATMEGA8U2 with ATMEGA16U2 chip, double the ISP FLASH capacity, which is convenient for more powerful function expansion and development needs. ATMEGA16U2 not only provides the traditional USB-to-serial function, but also allows users to program and define other functions. For example, the USB port can be configured as a mouse, keyboard, game joystick, camera, etc. Of course, these applications are still waiting for the Ad team. Announce specific implementation plans.
2. The external interface adds SDA and SCL on the basis of the 2011 version (position on the left side of AREF). The IOREF interface can provide a voltage reference to the Shield. In addition, a port is reserved on the left side of IOREF for future compatibility of series products.
3. The RESET circuit is improved compared to the 2011 version. To prevent accidental resetting of RESET, the RESET circuit is more stable.
About rd Mega:
rd Mega is a microcontroller development board with ATmega2560 as the core. It has 54 sets of digital l/O input/output terminals (14 of which can be used for PWM output), 16 sets of analog ratio input terminals, and 4 sets of UART (hardware serial ports), using 16 MHz crystal oscillator. Thanks to the bootloader, the program can be downloaded directly via USB without going through other external programmers. The power supply part can choose to supply power directly from USB, or use AC-to-DC adapter and battery as external power supply. Due to the open source code and the C language development environment using the Java concept (cross-platform), the peripheral modules and applications of rd grow rapidly. The main reason for attracting artists to use rd is that they can quickly use rd language to communicate with software such as Flash or Processing... to make multimedia interactive works. The rd development IDE interface is based on the principle of open source code, which allows you to download and use it for free in special production, school teaching, motor control, interactive works, etc.
