NXP Semiconductors FRDMSTBI-B3115

Overview

FRDMSTBI-B3115 from NXP is a sensor toolbox shield development board designed to interface with the FXPQ3115BVT1 high-precision biocompatible pressure sensor in 8-pin LGA (5 mm × 3 mm × 1.1 mm) package. It provides I²C-based digital pressure sensing capability, dual I²C bus support (I2C_SDA0/I2C_SCL0 and I2C_SDA1/I2C_SCL1), interrupt outputs (INT_1, INT_2), and dual VDD/GND supply connections for robust evaluation of medical-grade pressure sensing.

For engineers reviewing the FRDMSTBI-B3115 datasheet, FRDMSTBI-B3115 pinout, FRDMSTBI-B3115 application, or FRDMSTBI-B3115 equivalent, this board enables rapid prototyping of biocompatible pressure measurement systems using Arduino R3–compatible Freedom platforms such as FRDM-KL27Z, with direct integration into NXP's Sensor Toolbox software ecosystem.

Technical Context

The FRDMSTBI-B3115 implements a hardware abstraction layer between Arduino R3–pin-compatible NXP Freedom boards and the FXPQ3115BVT1 pressure sensor, supporting both I²C bus interfaces for flexible host controller routing. It routes all essential sensor signals-including two independent interrupt lines, dual power rails, and test points at key nodes-to facilitate signal integrity validation and debug during medical sensor integration.

Designed specifically for the FXPQ3115BVT1, the board includes no onboard MCU or firmware; operation relies entirely on host-side driver execution via NXP Sensor Toolbox software. All electrical interface characteristics (voltage levels, pull-up requirements, timing margins) are defined by the FXPQ3115BVT1 datasheet and Freedom board I²C peripheral capabilities.

FAQ

What is the primary function of the FRDMSTBI-B3115?

The FRDMSTBI-B3115 is a sensor toolbox shield development board that provides hardware interface and signal routing between Arduino R3–compatible NXP Freedom boards (e.g., FRDM-KL27Z) and the FXPQ3115BVT1 biocompatible pressure sensor. It does not contain processing logic or firmware; its role is strictly interconnect and signal conditioning for sensor evaluation within NXP's Sensor Toolbox software environment. The FRDMSTBI-B3115 enables rapid validation of pressure measurement accuracy, interrupt response, and I²C communication stability in medical-grade designs.

Which sensor is integrated on the FRDMSTBI-B3115?

The FRDMSTBI-B3115 has the FXPQ3115BVT1 high-precision biocompatible pressure sensor permanently mounted in an 8-pin LGA package (5 mm × 3 mm × 1.1 mm). This sensor is medically rated, features factory-calibrated output, and supports I²C digital communication. No other sensor variants or substitutions are supported on the FRDMSTBI-B3115 - the board is purpose-built exclusively for the FXPQ3115BVT1, and the FRDMSTBI-B3115 cannot operate without it.

Does the FRDMSTBI-B3115 include onboard microcontroller or firmware?

No, the FRDMSTBI-B3115 contains no microcontroller, memory, or embedded firmware. It is a passive shield board that routes sensor signals (I²C, interrupts, power) to the host Freedom board. All control, data acquisition, and calibration logic for the FRDMSTBI-B3115 must be executed on the host MCU (e.g., KL27Z) using NXP's Sensor Toolbox software stack. The FRDMSTBI-B3115 itself performs no signal processing or autonomous operation.

How do I connect and use the FRDMSTBI-B3115 in a development setup?

To use the FRDMSTBI-B3115, mount it onto an Arduino R3–compatible NXP Freedom board (e.g., FRDM-KL27Z), connect the assembly to a PC via USB, and install NXP Sensor Toolbox software from nxp.com/sensortoolbox. The FRDMSTBI-B3115 requires no additional drivers beyond those provided by the host Freedom board. Configuration, real-time pressure readout, and interrupt behavior testing are performed entirely within the Sensor Toolbox GUI - the FRDMSTBI-B3115 serves as the physical bridge enabling that interaction.

Are there alternative boards compatible with the FXPQ3115BVT1 sensor?

No official NXP alternative shield exists for the FXPQ3115BVT1. While custom carrier boards may be designed, the FRDMSTBI-B3115 remains the sole NXP-validated development platform for this sensor. Third-party breakout boards are not documented or supported for medical-grade use cases. For production integration, direct FXPQ3115BVT1 solder-down on custom PCBs is recommended - the FRDMSTBI-B3115 is intended solely for lab evaluation, not end-product deployment.
