Eight-Key Button Module, Active-Low, 3.3–5V

✅ Add eight inputs. Eight separate keys give a controller project individual controls.

✅ Read a press as low. Each press pulls the selected signal low, matching active-low logic.

✅ See the power state. A green indicator shows when the module has power.

✅ Check the pinout first. Verify the pin mapping and voltage limits before applying power.
