STH270N8F7-2 N-channel 80V, 1.7 mOhm, 180A power MOSFETs. The board provides a driving power circuit combined with a brake energy discharge circuit, allowing drive of the rotor position and management of the energy discharge. An onboard power management circuit generates all the reference voltages required.
The evaluation board supports real-time connectivity with the Ethercat communication protocol supported by the NETX90 network controller and hosts support for digital actuation with industrial IO management utilising the digital input current limiter CLT03-2Q3 and a single high-side switch IPS160H to drive the output loads. RS485 and RS422 interfaces are also catered for by the onboard ST3485 transceiver which can be used for digital sensors along with a quadrature encoder feedback signal input which is based on digital protocols like EnDat, BiSS and Ssi.
Sensing
STMicroelectronics have a rich portfolio of industrial MEMS sensors which are well suited to AGV and AMR applications, these include the ISM330DHCX 6-axis iNEMO IMU (accelerometer + gyroscope) with machine learning core, ISM330BX 6-axis IMU with embedded AI and sensor fusion and the ISM330IS 6-axis IMU with intelligent sensor processing unit (ISPU), these are all ideal for detecting the movement and rotation of an object. The IIS2DLPC 3D ultra-low-power accelerometer can be used to trigger low power wake-up following movement detection, the IIS2MDC 3D ultra-low-power magnetometer to detect absolute orientation of the object and the IMP34DT05 digital MEMS microphone for monitoring the surrounding environment for potential hazards.
power MCU enable applications that feature ultra-low power, 9 DoF motion sensing, wide-bandwidth vibration analysis, audio and ultrasound acoustic inspection, very precise local temperature, and environmental monitoring. A rich set of software packages is available in source code along with optimized firmware libraries and a complete companion cloud application which help to speed up the design cycle to develop end-to-end solutions. The kit supports a broad range of connectivity options, including a built-in RS485 transceiver, BLE, Wi- Fi, and NFC.
The
STWIN.box also includes a 34-pin expansion connector allowing the addition of other expansion cards which expand the capabilities of the development kit. The
STWIN.box is suitable for field trials, demonstrations and proof or concept for industrial IoT applications. The suite of sensors included on the
STWIN.box takes care of all the positioning requirements, but we will also need to integrate a very high-performance proximity sensor for accurate obstacle detection to ensure safe operation of the AGV/AMR.
Conclusion
STMicroelectronics motor control and sensing solutions exemplify the cutting-edge technology driving the future of automation, enabling the creation of intelligent, robust, and safe systems that can meet the diverse demands of modern industrial environments.
Design support
STMicroelectronics have included many of these MEMS sensors on the
STWIN.box (STEVAL-STWINBX1) development kit and reference design that simplifies prototyping and testing of advanced industrial sensing applications in IoT contexts such as condition monitoring and predictive maintenance.
The kit consists of an
STWIN.box core system, a 480mAh LiPo battery, an adapter for the ST-LINK debugger, a plastic case, an adapter board for DIL 24 sensors and a flexible cable. The many on-board industrial-grade sensors and the ultra-low

The compact VL53L4CD Time-Of-Flight (TOF) sensor presents an ideal solution, it has a 1mm to 1.2m detection range with an 18 degree Field-Of-View (FOV) and features excellent short distance linearity (>0.1cm). This new generation laser emitter TOF sensor has improved performance under ambient light conditions with fast ranging frequency up to 100 Hz. The sensor has a programmable interrupt threshold allowing it to wake up the host system when in energy saving mode along with ultralow power consumption down to 55 µA which has been adapted specifically for battery-powered devices. The VL53L4CD TOF sensor is available on the X-NUCLEO-53L4A1 sensor expansion board which can be paired with other STM32 Nucleo boards equipped with the Arduino R3 connectors. The board provides a complete evaluation kit that allows designers to learn, evaluate, and develop applications using the VL53L4CD Time-of-Flight high-accuracy proximity sensor. The expansion board comes complete with a cover glass holder which can be fitted with three different spacers of 0.25, 0.5, and 1 mm height below the cover glass to simulate various air gaps. A small oval cover glass fitting the sensor is included with the board.
