The SP901E is a compact, high‑performance LED pixel signal amplifier (sometimes called a repeater or buffer). It refreshes and boosts weakened SPI data so you can extend pixel runs, split a controller’s output into multiple branches, or drive mixed‑voltage pixels from the same controller. Thanks to its wide 5–24 V operating range and on‑board reverse‑polarity protection, the SP901E slots straight into new or existing installations and keeps them running reliably.
Inside you’ll find eight fully‑independent single‑signal outputs or four fault‑tolerant dual‑signal outputs (selectable automatically). That means you can take one pixel‑controller port and fan it out to eight 5 V WS2812B strips or four dual‑line WS2813/WS2815 strips, keeping the data voltage identical to your pixel voltage for rock‑solid integrity. Multiple amplifiers can be cascaded to cover very large projects.
For outdoor installations, mount the amplifier inside an IP‑rated enclosure.

The SP901E automatically configures itself for single‑line (DIN) or dual‑line (DAT/BI) protocols based on the signal it receives. For dual‑line chips (e.g. WS2813, SK6812‑RGBW, WS2815) you’ll have four mirrored outputs; for single‑line chips you’ll have eight independent outputs.
