Quick answer
If your littleBits Round LED Matrix is exposed to dust, scratches, or accidental drops, a silicone cover (like the littleBits Silicone Cover for o29 Round LED Matrix) provides a snug protective layer that attaches to the hand mount.
Why a silicone cover matters for your LED matrix
The littleBits Round LED Matrix is a popular component for displaying animations and sensor data, but its exposed surface can collect dust in a classroom or get scratched when stored loose in a kit. A silicone cover wraps around the matrix and clicks into the hand mount, adding a thin buffer without blocking the LEDs.
Because the cover is sold separately and does not include the LED matrix itself, you can retrofit it onto an existing matrix you already own. The low price makes it an inexpensive insurance against wear that could otherwise make your matrix harder to read or less appealing for student projects.
Diagnosis: Is your LED matrix cover damaged or missing?
- Symptom: Your Round LED Matrix shows visible scratches, dust buildup between the LEDs, or the original cover has torn or fallen off.
- Likely cause: Frequent handling, storage in a bin with other Bits, or repeated mounting and unmounting can wear down or dislodge the cover.
- Corrective action: Purchase a replacement littleBits Silicone Cover for o29 Round LED Matrix. Slide it over the matrix until it snaps into the hand mount. No tools required. Check that the cover fits snugly and does not block any LED pixels before using the matrix in a project.
- When to stop or choose another option: If the LED matrix itself has cracked or stopped lighting up, a cover will not fix internal damage. In that case, replace the entire Round LED Matrix module.
