The STEVAL-MKI231KA demonstration board provides a hardware platform for evaluating the STHS34PF80, an infrared motion and presence-detection sensor from STMicroelectronics. 

The demo board is connected through flat cable to a generic adapter board, the STEVAL-MKIGIBV5, to make it compatible with the STEVAL-MKI109V3 microcontroller board. An ad hoc plastic holder with a Fresnel lens (TMOS63-10) has been provided in the kit to enable the designer to verify the in-application performance of the device.

The STEVAL-MKIGIBV5 can be plugged into a standard DIL 24 socket. The kit supports the complete STHS34PF80 pin-out, and comes ready-to-use with the required decoupling capacitors on the power supply line.

This adapter is supported by the STEVAL-MKI109V3 motherboard, which includes a high performance 32-bit MCU functioning as a bridge between the sensor and a PC, on which it is possible to use the downloadable graphical user interface, or dedicated software routines for customized applications.

It is also possible to plug the board into an X-NUCLEO-IKS01A3, X-NUCLEO-IKS02A1 or X-NUCLEO-IKS4A1 board. The kit is supported by an X-CUBE-MEMS1 expansion software package for STM32 MCUs.


The EVB90394 evaluation board from Melexis provides an easy way to connect the MLX90394 Triaxis® magnetometer IC to a microcontroller or measurement device.

The MLX90394 IC is mounted on the EVB90394 together with a 100 nF decoupling capacitor and three pull-up resistors. Two precision headers are available for compatibility with the Melexis Triaxis DVKMagnetic board, which is supplied separately. 

The DVKMagnetic kit provides an easy way to connect the EVB90394 to magnetic devices such as a rotary knob, linear slider and joystick, which are included in the kit along with an off-axis magnet holder. The interface also provides pin-outs for an external LCD display and Arduino/Mbed boards, which are not included.


The RPR-0720-EVK is an evaluation board for the RPR-0720 infrared (IR) proximity sensor module. 

The ROHM RPR-0720 is an integrated IR proximity sensor module which combines an emitter and receiver in a single small package. 

The RPR-0720’s emitter is an IR vertical-cavity surface-emitting laser. The chip’s built-in IR receiver detects the approach of a person or other object by measuring the rate of reflection of IR light emitted by the VCSEL, over a range between 1 mm and 15 mm. The proximity sensing range is controllable by the system designer via its I2C interface.


The STEVAL-MKBOXPRO ( PRO) is the new ready-to-use programmable wireless box kit for developing any IoT application based on remote data gathering and evaluation, exploit the full kit potential by leveraging both motion and environmental data sensing, along with a digital microphone, and enhance the connectivity and smartness of whatever environment you find yourself into.


The AR0822NPSC10SMEAH3-GEVB sensor board for the 8 Mpixel AR0822 from onsemi provides a convenient platform for evaluating the image sensor’s embedded High Dynamic Range feature and its low power consumption. 

The board can be interfaced to the onsemi Demo 3 evaluation board, or to the AP1302 evaluation board stacked on the Demo 3 board. The combined kit uses the DevSuite software from onsemi to configure the system. The software provides a comprehensive set-up interface, and offers a flexible way to evaluate the sensor’s features and capabilities.

 The sensor board comes with a lens suitable for evaluation. Designers can use their own lens as long as it is compatible with the mechanical and optical requirements of the sensor.
