[hardware design] core-circuit DL : 0: ATmega2560通过USB接口与PC进行传输，供电电压为5V，内部晶振为16MHz。该芯片共有有54个I/O引脚，特别适用于需要大量I/O口电路，其中的16个可以提供脉宽调制（PWM）模拟输出，还有另外16个模拟输入引脚。在通信方面，有4个硬件串口，另外也可以支持SPI通信和I2C/TWI设备。设计核心电路中加入复位按键，通过USB串口进行通信。-ATmega2560 through the USB interface with the PC for transmission, power supply voltage of 5V, the internal oscillator is 16MHz. The chip has a total of 54 I/O pins, especially for applications that require a large number of I/O interface circuit, which can provide 16 pulse-width modulation (PWM) analog output, there is another 16 analog inputs. In communications, there are four hardware serial ports, in addition to also support SPI communication and I2C/TWI devices. Core circuit design added reset button, communicate through the USB port.
