Serial communication on pins TX/RX uses TTL logic levels (5V or 3.3V depending on the board). Don’t connect these pins directly to an RS232 serial port; they operate at +/- 12V and can damage your Arduino board. Hi I've got problems importing pyserial in both python 2.7 and 3.5 I've tried with pip install, easy_install, deb package, source balls. But always the same : >>;> import serial Traceback import serial python 中的串口 模块 serial 中常用方法 ser = serial.
