I have been repairing electronics and running a bench since the early 2000s, and importing and selling machines in Brazil since 2008. I founded Saber da Eletrônica, a Portuguese-language YouTube channel about board repair that has been online since 2018, and Robooster, which imports industrial machines from China. Since the end of 2024 I run both from Panama.
Tech Bench Lab exists because of a problem I kept hitting at my own bench: the driver or tool you need is scattered across forum threads, mirror sites and wrapped installers. Every guide here is written from the files themselves. When I publish a driver, I open the INF and list the VID:PID pairs it actually covers. When I link a download, I give the vendor’s own page and the SHA-256 of the file I verified, so you can check what you got. When a tool fails, I reproduce the error on real hardware before I write the fix.
What you will not find here: driver updaters, bundled installers, or “download buttons” that lead somewhere else. If a guide is wrong or out of date, write to contact@techbenchlab.com and I will fix it.
What you will find here
- Drivers and programmer software (CH340, CP210x, XGpro, RT809, AsProgrammer, Zadig and others), hosted on this site when the license allows it. Every hosted file is the unmodified vendor or project release, with version, size, SHA-256 and a link to the original next to the download button, so you can check it yourself. How we verify downloads.
- Step-by-step install and fix guides for Windows 11, macOS and Linux, based on vendor documentation and on real forum threads, which are linked.
- Comparison tables built from datasheets and manuals, not from marketing pages.
What you will not find: download wrappers, sign-up walls, fake buttons or rewritten press releases.
How it is kept current: posts are revised when a vendor ships a new version; the date at the top of each post is the last revision. Corrections and requests: contact@techbenchlab.com.
Tech Bench Lab is operated by MRS Corporation.
