AEK-CON-AFLVIP2 STMicroelectronics

AEK-CON-AFLVIP2 Data brief Adaptive front lighting connector board with VIPower board slot Features Designed to connect the following elements for a complete automatic front lighting (AFL) adjustment solution for a LED vehicle headlight: An MCU board such as the AEK-MCU-C4MLIT1 with 4x37 connector Two AEK-MOT-SM81M1 stepper motor boards An AEK-LED-21DISM1 LED driver control board with two L99LD21 LED drivers and providing four independent channels An EV-VNx actuator board such as the EV-VN7050AS to switch a headlight colling fan on and off Connected boards are controlled via three separate SPIs Input voltage from 8 V to 15 V DC DC Board size: 65 x 100 mm. Maximum component height: 27 mm Cables included for two stepper motor boards and one LED driver board WEEE and RoHS compliant All ST components are qualified Automotive grade Part of the AutoDevKit initiative Description The AEK-CON-AFLVIP2 connector board is designed to connect a car headlight solution demo featuring automatic adjustment of the low beam direction based on road geometry and tilt angles affected by weight distributions inside the car. The board can connect an MCU discovery board, such as the AEK-MCU-C4MLIT1 Product summary (with 4x37 connector), with two AEK-MOT-SM81M1 stepper motor boards governing AutoDevKit low beam direction (left-right and up-down), and a AEK-LED-21DISM1 LED driver AEK-CON-AFLVIP2 connector board board capable of supplying the different LED lights included in a modern front headlight assembly. It can also connect a high-side switch board from the EV-VNx MCU discovery range (e.g., EV-VN7050AS) to control a cooling fan for the LED headlight. board for SPC5 Chorus 4M AEK-MCU- The AEK-CON-AFLVIP2 board is part of the AutoDevKit initiative, which allows you to automotive C4MLIT1 build and test various application prototypes from a set of available boards and microcontroller with generating the dedicated drivers and pin assignments using the SPC5-Studio CAN transceivers integrated development environment.
