Python 3.5 or above is required; new tests require 3.6 or above, as they rely on fstring syntax (PEP_498) and variable annotation syntax (PEP_526).

Python 3.5 has reached end-of-life on September 5th, 2020. PyFtdi v0.52 is the last PyFtdi version to support Python 3.5.

PyFtdi relies on PyUSB, which itself depends on one of the following native libraries:

  • libusb, currently tested with 1.0.23

PyFtdi does not depend on any other native library, and only uses standard Python modules along with PyUSB and pyserial.

PyFtdi is beeing tested with PyUSB 1.0.2.


PyFtdi is developed on macOS platforms (64-bit kernel), and is validated on a regular basis on Linux hosts.

As it contains no native code, it should work on any PyUSB and libusb supported platforms. However, M$ Windows is a seamless source of issues and is not officially supported, although users have reported successful installation with Windows 7 for example. Your mileage may vary.
