This collection offers official WCH (WCH.CN) USB-to-serial port drivers commonly used for CH340, CH341 and related chips. You’ll find downloads for Windows (32/64-bit, including Server editions), macOS (Intel and Apple Silicon), and Linux (kernel modules), plus legacy builds for older releases. Supported devices include USB serial adapters, Arduino-compatible boards, label printers, barcode scanners, POS terminals and programmer cables.
Each driver page includes direct download links, version details, file size and checksum where available. Installation notes cover running the Windows installer or .inf update, enabling kernel extensions or granting permissions on macOS, and loading the module or installing via package manager on Linux. Compatibility notes indicate which OS versions and architectures are tested; select the matching package for your device and OS.
Download only drivers that match your chip model and OS to avoid connection errors. If a driver is unsigned, the page explains how to allow it during installation and points to troubleshooting steps for common issues.
