Adaptive Headlight Connector Board with VIPower Board Slot

AEK-CON-AFLVIP2

Overview

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 (with 4x37 connector), with two AEK-MOT-SM81M1 stepper motor boards governing low beam direction (left-right and up-down), and a AEK-LED-21DISM1 LED driver 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 range (e.g., EV-VN7050AS) to control a cooling fan for the LED headlight.
The AEK-CON-AFLVIP2 board is part of the AutoDevKit initiative, which allows you to build and test various application prototypes from a set of available boards and generating the dedicated drivers and pin assignments using the SPC5-Studio integrated development environment.

Main 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_DC to 15 V_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
