Found on the beach: a custom or OEM RGB seven‑segment display module, tailored for a specific device or manufacturer. One side of the object features a digital display with a three-digit readout, the letters ‘L’ and ‘R’ in blue and green respectively, a lightning bolt icon, and a distinctive logo composed of multi-coloured fan-like blades. The reverse side shows a printed circuit board marked ‘KRS‑2519CRGB‑1’ and ‘2520’, alongside gold-plated contacts and through-holes indicative of surface mounting.
The part number, ChatGPT, advises does not appear in public electronics catalogs or databases, suggesting the component was produced either for internal use by a specific brand or as part of a mass-produced but undocumented consumer device. The inclusion of ‘CRGB’ implies RGB lighting capability, meaning the segment display can change colour, possibly to indicate power levels, warnings, or operational states. The number ‘2520’ may refer to a production batch or date code, such as week 20 of the year 2025.
Such displays are commonly used in e‑bikes, electric scooters, children’s ride-on vehicles, smart sports gear, or small remote-controlled electronics. The L/R notation may signify directional indicators, balance sensors, or audio channel outputs. The lightning bolt icon, a near-universal symbol for electricity or charge, hints at a function related to battery monitoring. The visible wear and absence of surrounding components suggest the item was once embedded in a plastic housing, likely waterproof or weather-resistant, before being separated and washed ashore.
Despite the lack of direct identification, other modules with similar codes, such as KRS‑2351AW, are listed on electronics supplier sites as LED or RGB seven‑segment displays, used in meters, control panels, or dashboard-style readouts.
