2.1 Functional Description
This section provides a functional description of the Sensor Hub BoosterPack.
2.1.1 BoosterPack XL Connector
The BoosterPack XL connector attaches the BoosterPack to the Tiva TM4C LaunchPad. This
BoosterPack is specifically designed to match the pin function with the Tiva TM4C LaunchPad. Basic I

C
and UART communication to the sensors and RF expansion connectors are also available when the
Sensor Hub is connected to either the C2000 or MSP430 LaunchPad.
Table 2 describes the BoosterPack XL interface connections and the respective uses on the Sensor Hub
BoosterPack. It also shows which pins remain available for additional expansion at the user's discretion.

2.1.2 TMP006 Temperature Sensor
The TMP006 provides both direct and indirect temperature measurements. It contains an on-chip
temperature sensor to directly measure ambient temperature conditions. It also allows contactless infrared
object temperature measurement.
2.1.3 InvenSense MPU9150 9-Axis Motion Sensor
The MPU9150 is a 3-axis accelerometer, 3-axis gyroscope, and 3-axis magnetometer in a single package.
This device is the primary motion sensor on the Sensor Hub. It is used by the demonstration software as
the raw motion inputs, which are fused by a direct cosine matrix into roll, pitch, and yaw measurements.
2.1.4 Intersil ISL29023 Ambient and Infrared Light Sensor
The ISL29023 provides sensor measurements of light conditions across both the ambient (human-visible)
spectrum and the infrared spectrum.
2.1.5 Sensirion SHT21 Humidity Sensor
The SHT21 provides relative humidity measurements.
2.1.6 Bosch BMP180 Barometric Pressure Sensor
The BMP180 measures barometric pressure conditions. It can be used to enhance the motion sensor by
determining relative changes in altitude.
2.1.7 Low-Power RF Expansion Connection
The RF expansion connection provides a wide array of options to the end application.
