3 x 4 12 鍵矩陣薄膜鍵盤

The 7-pin Dupont connector made wiring this into my breadboard project incredibly simple. The adhesive backing held firmly to my enclosure, and the 0.8mm thickness is perfect for a low-profile design. Exactly what I needed for my numeric input panel.

I mounted this to a breadboard project and all 12 keys responded immediately—no ghosting or dead spots. The adhesive back stuck cleanly to my enclosure, and the thin 0.8mm profile fits neatly under a panel. Perfect for adding numeric input without taking up much space.

Finally, a membrane keypad that actually fits my compact projects. The self-adhesive back made mounting it to my prototype a breeze, though the 86mm cable is just barely long enough for my enclosure.
