STMicroelectronics

The STEVAL-MKI250KA demonstration kit from STMicroelectronics comprises: 

  • STEVAL-MKI250A biosensor board, which provides access to the complete pinout of the ST1VAFE3BX vertical analog front-end (vAFE) together with the required decoupling capacitors on the power-supply lines
  • STEVAL-MKE006A and STEVAL-MKE007A electrode boards

An ECG cable with a 3.5 mm phone jack can be plugged in when the STEVAL-MKE007A electrode board is used.

The STEVAL-MKI250KA kit is compatible with the STEVAL-MKI109V3 and STEVAL-MKI109D motherboards.

The kit includes a high-performance 32-bit microcontroller functioning as a bridge between the sensor and a PC, on which it is possible to use the downloadable MEMS Studio graphical user interface software, or dedicated software routines for customized applications.

The EVLPWD-FAN-PUMP evaluation board for the PWD5T60 motor driver power stage from STMicroelectronics supports flexible, ready-to-use control methods, and so helps to accelerate the development of reliable, compact and efficient fans and pumps. 

The EVLPWD-FAN-PUMP board features the PWD5T60 and an STM32G0 microcontroller based on an Arm® Cortex®-M0+ core, enabling field-oriented control (FOC) or six-step control of permanent magnet synchronous motors (PMSM) and brushless dc (BLDC) motors. The board offers a choice of single- or triple-shunt current sensing. Because the PWD5T60 is highly integrated, it has enabled STMicroelectronics to implement the board’s motor power stage in a small circular form factor, making it ideal for use in fans and pumps. It also includes a power-supply circuit which provides 12 V and 3.3 V supply voltages for the application, with a complete ac line filter at the input stage.

The EVLPWD-FAN-PUMP includes built-in bus-voltage detection to help to take advantage of the safety design of the PWD5T60, which provides over- and under-voltage lockout protection for each bootstrap circuit to prevent unsafe or inefficient operation. 

The PWD5T60 is also robust, and features shoot-through protection with interlock and preset default dead time, providing fail-safe protection against shoot-through currents. Additionally, the PWD5T60 withstands voltage drops below ground.

The board is ready to use and runs the FOC and 6-step control firmware included in the X-CUBE-MCSDK motor control software development kit, which is available free of charge from the ST website.
