Source note
Compiled from the HD-B8L specification V1.0 (May 15, 2025). maxLoadingPixels is the single-card figure (1,300,000); the 5,240,000 figure applies to cascading several units and is kept in specs. The document prints the maximum width/height in the same sentence as the cascading capacity. No per-port capacity is printed. 4G/5G needs the optional module, so cellular4G is left null. The TTL interface accepts external sensors or GPS; no built-in GPS is stated. The product is a bare board (no enclosure).
