I finally got it wired up with the common cathode setup and the display is crisp and bright even in a well-lit room. The forum manual had the exact pinout I needed, which saved me from guessing.

Matthew M. ★★★★★ Oct 21, 2026

The pinout documentation in the support forum made setup a breeze—I had it wired to my Arduino within ten minutes. The common cathode design is straightforward, and the digits are crisp and evenly lit.

Finally a 7-segment display that doesn't require me to guess the wiring—the pinout in the manual matched the module perfectly, and I had it running in under ten minutes. The digits are crisp and bright, exactly what I needed for my clock project.
