从淘宝上买的摄像头没注意,发过来的是RS232的版本,所以需要把MAX3232的芯片拆掉后,才能接到Arduino UNO的板子上.

The MAX3232 takes 0-5V signal and outputs +- 13.2V. You can only use 0-5V signal on Arduino so remove the chip.

The second picture is pretty clear:

There is an empty foot print for a chip and two jumper wires were soldered on. If you don't order RS232 version by mistake you don't need this step.

Do you have this exact camera?

You need to know this too:

由于摄像头输出的TTL电平是3.3V的,所以在与5V的Arduino板接线时,输入端最好用两个10K左右的电阻做一下分压,以免人品不好损坏电路.

I have a few water-proof version of this camera. If you use hardware serial, it's working fine. If you use software serial, too many frames are garbled (10%).
