Source note
Compiled from the HD-B6L specification V1.3 (Jun. 3, 2025). The document prints the capacity as "130W pixels" for a single B6L and "260W pixels" for cascade splicing of multiple B6L; W is the Chinese unit of 10,000, so maxLoadingPixels is recorded as 1,300,000 (single unit). No per-port capacity and no board thickness are printed (size is 157mm×130mm; the dimension drawing shows 157.27 × 130.30). 4G needs the optional 4G module, so cellular4G is left null; GPS needs an external GPS module on the GPS interface, so gps is left null. The product is a bare board (no enclosure).
