STMicroelectronics STEVAL-MKBOXPRO

Overview

STEVAL-MKBOXPRO from STMicroelectronics is a ready-to-use programmable wireless development kit for IoT sensor node prototyping, integrating an STM32U585AI Arm Cortex-M33 microcontroller with TrustZone®, Bluetooth 5.2 (STM32WB07), NFC (ST25DV04K), microSD slot, and seven high-precision sensors-including LSM6DSV16X (6-axis IMU), LPS22DF (pressure), STTS22H (temp), LIS2DU12 (accel), LIS2MDL (magnetometer), and MP23DB01HP (digital microphone)-in a 40×63 mm palm-sized enclosure with 480 mAh battery and USB-C/wireless charging.

For engineers reviewing the STEVAL-MKBOXPRO datasheet, STEVAL-MKBOXPRO pinout, STEVAL-MKBOXPRO application, or STEVAL-MKBOXPRO equivalent, this kit supports rapid evaluation across Entry (preloaded apps via STBLESensor), Expert (graphical configuration), and Pro (STM32 ODE + Function Packs) development modes-enabling motion, environmental, audio, AI/MLC, NFC, and data-logging use cases without hardware modification.

Technical Context

The STEVAL-MKBOXPRO implements a multi-sensor edge node architecture centered on the STM32U585AI MCU, which integrates Arm Cortex-M33 with FPU, TrustZone security, and ultra-low-power operation (down to 19 nA in standby with RTC & 32 kB RAM retention). Sensor fusion is performed onboard using ST's X-CUBE-MEMS1 and X-CUBE-AI libraries.

Wireless connectivity combines dual-core Bluetooth 5.2 (STM32WB07) for BLE communication and over-the-air firmware updates, plus ST25DV04K NFC tag for secure pairing and configuration. Environmental and inertial data are acquired simultaneously at configurable ODRs up to 6.6 kHz (LSM6DSV16X) and logged locally to microSD or streamed via BLE.

FAQ

What firmware update methods does STEVAL-MKBOXPRO support?

STEVAL-MKBOXPRO supports three firmware update methods: over-the-air (FOTA) via BLE using the STBLESensor app, wired DFU through USB-C using STM32CubeProgrammer, and local microSD card loading. All methods preserve user configuration and sensor calibration data. The board's STM32U585AI bootloader validates firmware signatures before execution to ensure secure updates.

How does the Qvar capacitive touch interface function on this kit?

The Qvar electrodes on STEVAL-MKBOXPRO implement a self-capacitive touch sensing channel using the STM32U585AI's built-in CORDIC and AES accelerators. It supports proximity detection, swipe gestures, and multi-electrode UI configurations without external components. Calibration is automatic during boot, and raw capacitance values are accessible via ST's X-CUBE-TOUCH library.

Can the LSM6DSV16X and LIS2DU12 operate simultaneously at full bandwidth?

Yes-the LSM6DSV16X (up to 6.6 kHz ODR) and LIS2DU12 (up to 1.6 kHz ODR) can stream concurrently via independent I²C buses routed to separate MCU pins. Their data is synchronized using the STM32U585AI's hardware timestamping unit, enabling precise temporal alignment for vibration analysis or gait recognition without host CPU intervention.

Is the ST25DV04K NFC tag pre-configured for specific use cases?

The ST25DV04K is factory-programmed with a unique UID and default NDEF message containing board revision, firmware version, and sensor calibration IDs. Users can rewrite the NDEF area via I²C or RF to store custom configuration tokens, device credentials, or pairing keys-leveraging its dual-interface capability for secure provisioning in production or field service workflows.
