16-channel led driver with 16-bit apdm control

Advertisement

General Description
This development kit features a universal control board and an
AL58263 driver board, both powered via USB Type-C.
The universal board is equipped with an automotive grade 32-bit Arm
M0 core MCU and integrates LIN, CAN, and UART communication
interfaces to provide display data to the AL58263 driver board. The
AL58263 board includes 16 RGB LEDs, controlled by three
integrated AL58263 ICs, enabling precise control of lighting effects.
This kit supports daisy chaining of up to two driver boards, making it
ideal for automotive applications such as instrument clusters, lighting,
and other LED-based displays in both automotive and commercial
environments.
