STMicroelectronics AEKD-AFLLIGHT1

Overview

AEKD-AFLLIGHT1 from STMicroelectronics is an assembled adaptive front lighting (AFL) simulation kit for automotive development, integrating two stepper motors (azimuth/elevation), four LED strings (high beam, low beam, DRL, turn indicator), and a cooling fan in a 400 × 200 × 140 mm plexiglass housing. It serves as a physical load interface for AFL control prototyping.

For engineers reviewing the AEKD-AFLLIGHT1 datasheet, AEKD-AFLLIGHT1 pinout, AEKD-AFLLIGHT1 application, or AEKD-AFLLIGHT1 equivalent, this kit enables rapid validation of motor sequencing, LED timing profiles, thermal management logic, and SPI-driven load coordination in AutoDevKit-based AFL ECU development.

Technical Context

The AEKD-AFLLIGHT1 functions as a passive load module-no onboard intelligence or MCU-relying entirely on external drive signals from companion boards like AEKD-AFLPANEL1. Its two bipolar stepper motors accept full-step or microstep commands via H-bridge drivers (e.g., AEK-MOT-SM81M1), while each LED string operates at +12 V with dedicated current paths and polarity-aware connectors.

All loads are prewired to two standardized JPX2/JPX3 connectors matching AEKD-AFLPANEL1's output headers. The fan provides active thermal regulation during extended high-beam or DRL operation, and mechanical alignment allows precise angular displacement simulation across ±15° horizontal and vertical ranges.

FAQ

Does AEKD-AFLLIGHT1 include an onboard microcontroller or driver ICs?

No. AEKD-AFLLIGHT1 contains no active electronics-it is a passive load kit. All driving logic, motor current control, and LED switching must be provided externally, typically by AEKD-AFLPANEL1 or compatible AutoDevKit ECU boards such as AEK-MCU-C4MLIT1 with AEK-MOT-SM81M1 motor drivers.

What voltage levels and signal types does AEKD-AFLLIGHT1 accept?

AEKD-AFLLIGHT1 accepts only +12 V DC power across its motor and LED loads. It does not process digital signals directly; instead, it relies on external H-bridge drivers to translate SPI or GPIO commands into bidirectional current flow for stepper coils and switched +12 V for LED strings, per the DB3997 schematic.

Can AEKD-AFLLIGHT1 be used without AEKD-AFLPANEL1?

Yes, but only with equivalent external drive hardware. Its JPX2/JPX3 connectors follow AutoDevKit pinout conventions, so any board providing matched stepper phase outputs, LED enable lines, and +12 V distribution-such as custom carrier boards using AEK-MOT-SM81M1 and AEK-LED-21DISM1-can interface directly.

Is mechanical mounting hardware included with AEKD-AFLLIGHT1?

No mounting brackets, screws, or fixtures are supplied. The kit is intended for benchtop use with optional third-party clamping or optical rail integration. Its 400 × 200 × 140 mm footprint and flat base allow stable placement on standard lab surfaces during dynamic AFL angle testing.
