STMicroelectronics AEK-CON-SENSOR1

Overview

AEK-CON-SENSOR1 from STMicroelectronics is a compact (56 mm × 41 mm) connector board that interfaces DIL 24–socketed MEMS sensor boards-including STEVAL-MKI193V1, STEVAL-MKI208V1K, and MP23DB01HP-with the AEK-MCU-C4MLIT1 SPC5 Chorus automotive MCU discovery board. It provides 1.8 V regulated power via an integrated LD1117 LDO, supports SPI/TDM/PDM sensor communication protocols, and enables interrupt-driven sensor data acquisition in automotive embedded systems.

For engineers reviewing the AEK-CON-SENSOR1 datasheet, AEK-CON-SENSOR1 pinout, AEK-CON-SENSOR1 application, or AEK-CON-SENSOR1 equivalent, this page delivers verified interface topology, supported sensor protocols (SPI, TDM, PDM), voltage regulation specs, mechanical dimensions, and AutoDevKit integration details required for rapid SPC5-based sensor evaluation.

Technical Context

The board implements dual-header connectivity: a 5×2 male header links to AEK-MCU-C4MLIT1 for 3.3 V supply, SPI (CS/SCL/SDA/SDO), and two interrupt lines (INT1/INT2); a 7×2 male header provides optional GPIO expansion. Three female headers-12×2 for DIL 24 MEMS sensors and two 3×2 for stereo digital microphones-enable modular sensor attachment.

Onboard LD1117-1.8 LDO regulates input VDD3.3 to stable 1.8 V for MEMS sensor core logic, with 100 nF and 1 µF local decoupling. The VDD-SEL jumper allows selection between 1.8 V and 3.3 V I/O supply to match sensor voltage domains, supporting both AIS2IH (SPI) and MP23DB01HP (PDM) families.

FAQ

Does AEK-CON-SENSOR1 require an external power supply?

No. It draws 3.3 V power directly from the AEK-MCU-C4MLIT1 board via its 5×2 main connector. The onboard LD1117-1.8 LDO converts this to regulated 1.8 V for MEMS sensor cores, eliminating need for external regulators or batteries during evaluation.

Which sensor communication protocols does AEK-CON-SENSOR1 support?

It supports SPI (4-wire), TDM (2-line), and PDM (2-line) protocols. These match native outputs of ST sensors like AIS2DW12 (SPI), IIS3DWB (TDM), and MP23DB01HP (PDM), enabling direct connection without level-shifting or protocol translation.

Can AEK-CON-SENSOR1 be used with non-ST MEMS boards?

Only if they conform to the DIL 24 mechanical footprint and use compatible voltage levels (1.8 V or 3.3 V I/O) and pinout alignment with ST's reference designs (e.g., STEVAL-MKI208V1K). Non-ST boards may require manual signal mapping verification against the schematic in DB4413 Rev 2.

Is AutoDevKit software support included with AEK-CON-SENSOR1?

Yes. The board is fully integrated into ST's SPC5-STUDIO IDE via the STSW-AUTODEVKIT plugin, providing automatic driver generation, sensor configuration wizards, and real-time data visualization for all supported STEVAL sensor boards.
