Automotive Grade 8-Channel Matrix LED Driver Board with CAN FD & AEC-Q100 Control

RM Cortex-M7 MCU for adaptive matrix headlight control system
Waterproof automotive lighting controller interface with CAN FD support

Automotive Grade 8-Channel Matrix LED Driver Board with CAN FD & AEC-Q100 Control

This Adaptive Driving Beam (ADB) LED Driver is a high-performance constant current drive platform engineered specifically for modern smart vehicle lighting systems. Acting as the "intelligent power core" of automotive lighting, the product strictly adheres to AEC-Q100/101/200 certification standards. It utilizes a six-layer PCB stack-up design with high-TG FR-4 substrate, covering a full automotive-grade operating temperature range of -40°C to +125°C. With ISO 26262 ASIL-B functional safety certification, it provides zero-failure performance assurance for both OEM and aftermarket upgrade markets.
