STMicroelectronics Profi MEMS Tool development platform

Click2Contact

The Profi MEMS Tool development platform by STMicroelectronics lets engineers visualise the behavior of ST’s MEMS sensors, helping accelerate time to market and maximise the performance of product designs.

Featuring a high-performing STM32F401 microcontroller and flexible power management, the main Profi MEMS Tool board powers the sensors and gathers output data for forwarding to a developer GUI (graphical user interface) running on a host PC. Users are free to use ST’s UNICO GUI, which can be downloaded from the ST website, or a tool of their choice to analyse the MEMS sensor waveforms.

The tool goes beyond simply linking the sensors and GUI, by helping users explore all the operating modes and power settings and optimise performance. The board’s generous compute power handles complex datasets, such as OIS/EIS (optical or electronic image stabilisation) from ST’s 6-axis inertial modules, as well as simple sensor readings like barometric pressure and accelerometer or gyroscope data. It also has ample capability for evaluating the latest generation of high-resolution MEMS sensors for industrial applications, such as the IIS3DHHC 3-axis low-noise accelerometer, which features a 16-bit accelerometer output and 12-bit temperature output.

To begin a project, the user connects the desired sensor modules via expansion headers provided on the main board. Software-adjustable power circuitry gives flexibility to set the sensor supply voltage from 0 to 3.6 V to replicate likely operating conditions in the intended application. The board provides power monitoring that allows users to detect the sensor supply voltage and current drawn without connecting external instruments, which streamlines development of energy-conscious projects such as Internet-of-Things (IoT) devices, smart sensors or controllers for mobile robots or drones.
