Design features

Protection — resettable input fuse, reverse-polarity protection, and independently fused backlight and panel branches (a shorted backlight harness trips only its own branch)
Thermal management — an on-board sensor driving graduated backlight power reduction at temperature extremes, with an external sensor input
Field-programmable panel support — up to five stored panel timing profiles plus a protected factory default and a boot-time selector.
Fail-safe service — dual firmware images, USB-C update in under a minute, block-verified, automatic fallback on interruption
