HSP-1920 LCD Controller Board

The HSP-1920 is a version of the SP-1920, released in 2017, for harsher environments. Designed for video signals up to 1920x1200 and LCD panel resolutions up to 1920x1200 with LVDS connectivity. The HSP-1920 meets the needs of many applications but is likely to appeal most to the Digital Signage market given the built-in MP4 fail-over media player, and the legacy industrial market for its Composite video input. The HSP-1920 is supported by a wide selection of panel connection cables and other accessories together with system development documentation including 3D drawings.
