NXP Semiconductors KITMPXV5004DPEVB

Overview

KITMPXV5004DPEVB from NXP Semiconductors (formerly Freescale) is an evaluation board designed to demonstrate and develop with the MPXV5004DP differential pressure sensor for medical, industrial, and consumer applications requiring precise analog output pressure measurement across 0–4 kPa range.

For engineers reviewing the KITMPXV5004DPEVB datasheet, KITMPXV5004DPEVB pinout, KITMPXV5004DPEVB application, or KITMPXV5004DPEVB equivalent, this board provides USB-enabled plug-and-play operation, GUI-driven demo/evaluation/tutorial modes, and direct interface to the MPXV5004DP sensor for rapid prototyping of pressure-sensing functions including liquid-level monitoring, respiratory flow sensing, and HVAC differential pressure control.

Technical Context

The KITMPXV5004DPEVB implements a unified hardware-software architecture built around the MPXV5004DP piezoresistive silicon pressure sensor, delivering ratiometric analog output (0.2–4.7 V) proportional to applied differential pressure. It integrates signal conditioning circuitry and USB-to-serial bridge (FTDI) for real-time data streaming.

Designed as part of the Xtrinsic Sensor Toolbox, the board supports firmware-upgradable sensor algorithms-including PSI conversion and zero-offset calibration-and interfaces directly with Freescale/NXP's complimentary GUI software available at freescale.com/sensortoolbox for live visualization and parameter tuning.

FAQ

What is the primary function of the KITMPXV5004DPEVB evaluation board?

The KITMPXV5004DPEVB evaluation board is designed to enable rapid development and validation of differential pressure sensing using the MPXV5004DP sensor. It provides USB connectivity, real-time analog output monitoring via GUI, and calibrated signal conditioning-allowing engineers to evaluate pressure response, implement zero-pressure offset correction, and integrate pressure data into host systems without custom hardware design. The KITMPXV5004DPEVB supports immediate out-of-box testing of respiratory flow, liquid level, and HVAC duct pressure applications.

Does the KITMPXV5004DPEVB require additional software or drivers to operate?

No, the KITMPXV5004DPEVB uses an FTDI USB-to-serial bridge and is recognized as a standard COM port on Windows, macOS, and Linux without proprietary drivers. The Freescale Sensor Toolbox GUI software-required for full functionality including real-time plotting, calibration, and data export-is freely downloadable from freescale.com/sensortoolbox. This GUI is the only software dependency for operating the KITMPXV5004DPEVB beyond basic serial terminal access.

Can the KITMPXV5004DPEVB be used with microcontrollers other than NXP devices?

Yes, the KITMPXV5004DPEVB outputs analog voltage (0.2–4.7 V) from the MPXV5004DP sensor, making it compatible with any microcontroller or DAQ system featuring a 5 V-tolerant ADC input. While optimized for integration with NXP's Xtrinsic ecosystem and GUI, its analog interface allows direct connection to Arduino, Raspberry Pi, STM32, or TI MSP430 platforms-provided appropriate voltage scaling and sampling rate alignment are implemented. The KITMPXV5004DPEVB does not restrict host processor choice.

What pressure range and accuracy does the KITMPXV5004DPEVB support through the MPXV5004DP sensor?

The KITMPXV5004DPEVB hosts the MPXV5004DP, which measures differential pressure from 0 to 4 kPa (0–580 psi) with total error band of ±2.5% of full-scale span over 0–85°C. Its ratiometric output ensures stability against supply voltage variation, and factory-trimmed temperature compensation enables reliable operation in medical and industrial environments. The KITMPXV5004DPEVB preserves this specification without added error, supporting accurate low-range pressure detection critical for blood pressure monitors and dialysis systems.

Is the KITMPXV5004DPEVB still supported given NXP's acquisition of Freescale?

Yes, the KITMPXV5004DPEVB remains a supported legacy evaluation tool under NXP's product continuity program. Documentation, GUI software, and reference designs are archived and accessible via NXP's official website (nxp.com) under "Legacy Sensors" and "Xtrinsic Sensor Toolbox" sections. While no new revisions are planned, NXP guarantees long-term availability of the KITMPXV5004DPEVB for existing design-in and maintenance use cases, and the KITMPXV5004DPEVB continues to be stocked and distributed through authorized channels including Aetrix Electronics.
