Texas Instruments BOOSTXL-SENSHUB

Overview

BOOSTXL-SENSHUB from Texas Instruments is a Sensor Hub BoosterPack extension board designed exclusively for the Tiva™ C Series TM4C123GXL LaunchPad evaluation platform. It integrates five environmental and motion sensors-including TMP006 (infrared temperature), MPU9150 (9-axis motion), BMP180 (barometric pressure), ISL29023 (ambient/infrared light), and SHT21 (humidity)-along with user buttons, LED indicators, RF expansion capability, and a TPS75118 1.8-V regulator, enabling rapid prototyping of sensor-fused embedded applications.

For engineers reviewing the BOOSTXL-SENSHUB datasheet, BOOSTXL-SENSHUB pinout, BOOSTXL-SENSHUB application, or BOOSTXL-SENSHUB equivalent, this page delivers verified hardware specifications, software integration context with TivaWare SensorLib, compatibility with EK-TM4C123GXL and EK-LM4F120XL LaunchPads, and practical guidance for sensor fusion development, RF module interfacing, and firmware deployment using CCS/Keil/IAR toolchains.

Technical Context

The BOOSTXL-SENSHUB operates as a plug-in hardware extension that interfaces via TI's standardized BoosterPack XL headers-providing I²C (I2C1, I2C3), UART (TX/RX/RTS/CTS), SSI, and GPIO signals to the host LaunchPad MCU. All on-board sensors communicate over I²C, with dedicated interrupt lines routed to MCU GPIOs for low-latency event handling.

It features dual power domains: 3.3 V supplied directly from the LaunchPad, and a regulated 1.8 V rail generated by the TPS75118 LDO for RF expansion modules. The board includes an EM connector for wireless add-ons and supports TivaWare SensorLib-a vendor-provided, production-ready driver library abstracting sensor initialization, data acquisition, and calibration across all five integrated sensors.

FAQ

What is the BOOSTXL-SENSHUB used for?

The BOOSTXL-SENSHUB is a sensor-fusion development board that extends the Tiva C Series LaunchPad with five calibrated environmental and motion sensors. It enables rapid prototyping of applications such as gesture-controlled interfaces, indoor navigation, predictive maintenance monitors, and multi-sensor IoT edge nodes-all supported by TI's TivaWare SensorLib drivers and example firmware.

Which microcontroller platforms does the BOOSTXL-SENSHUB support?

The BOOSTXL-SENSHUB is fully compatible with both the Tiva™ C Series EK-TM4C123GXL LaunchPad and the legacy Stellaris® EK-LM4F120XL LaunchPad. Its BoosterPack XL pinout ensures mechanical and electrical interoperability with these platforms, delivering consistent I²C, UART, and GPIO access without adapter hardware or PCB modification.

Does the BOOSTXL-SENSHUB include software support?

Yes-the BOOSTXL-SENSHUB is fully supported by TI's TivaWare for C Series software package, including the SensorLib driver library, pre-built examples (e.g., sensor fusion, real-time orientation tracking), and source code installed under C:\ti\TivaWare_C_Series_<version>\examples\boards\ek-tm4c123gxl-senshub\. Projects are provided for Code Composer Studio, Keil, IAR, and Sourcery CodeBench.

How is RF expansion implemented on the BOOSTXL-SENSHUB?

The BOOSTXL-SENSHUB provides an EM (extension module) connector supporting RF expansion via dedicated 1.8-V power (from TPS75118), I²C (RF_I2C_SCL/SDA), reset/shutdown control lines, and four configurable GPIOs (RF_GPIO0–3). This interface is designed for seamless integration with TI CCxxxx or third-party wireless modules compliant with the EM standard.

Are the on-board sensors factory-calibrated and accessible through unified APIs?

Yes-each sensor (TMP006, MPU9150, BMP180, ISL29023, SHT21) is pre-mounted and electrically validated. TivaWare SensorLib provides unified, register-abstracted APIs for initialization, data read, and basic compensation-enabling developers to acquire synchronized sensor streams without low-level register programming or calibration math.
