关于Ethernet

小小怪

怎么通过USB转串口模块给Arduino Ethernet板子下载程序，能详细说说其引脚的用法吗？我的USB模块用的芯片是CH340

奈何col

rx连tx，tx连rx，gnd连gnd，然后手动复位

The 6-pin serial programming header is compatible with the USB Serial adapter and also with the FTDI USB cables or with Sparkfun and Adafruit FTDI-style basic USB-to-serial breakout boards. It features support for automatic reset, allowing sketches to be uploaded without pressing the reset button on the board. When plugged into a USB to Serial adapter, the Arduino Ethernet is powered from the adapter. 具体你看一下电路图
