PySerial

PySerial is a widely used, cross-platform Python library that provides essential functionality for serial port communication. It allows Python scripts to easily interact with a broad range of hardware devices, including microcontrollers (like Arduino and Raspberry Pi), GPS modules, industrial sensors, and other serial-enabled peripherals across Windows, Linux, and macOS. Currently at version 3.5, PySerial maintains an active development cycle, releasing bug fixes and minor feature updates periodically.
