Sensor Hub BoosterPack
The Sensor Hub BoosterPack is packed with an impressive list of sensors, around two applications: an inertial measurement unit and a weather station.
The inertial measurement unit relies on the InvenSense MPU9150 motion sensor, which includes a 3-axis gyroscope, a 3-axis accelerometer and and 3-axis magnetometer. The MPU9150 also features its own processor to compute Euler angles. The weather station uses the following sensors:
The Sensor Hub BoosterPack also provides two press-buttons, one LED and an additional connector for a daughter radio board.
This BoosterPack has been updated with the Sensors BoosterPack. |
Hardware
All the sensors are connected to the same I²C bus, requiring only 2 pins.
Unfortunately, the I²C bus for the sensors uses pins 14 (PB_6 clock) and 15 (PB_7 data), which are not I²C capable by standard. The Stellaris now Tiva C Series LaunchPad requires the R9 and R10 shunts in order to re-direct the I²C port 3 from pins 23 (PD_0 clock) and 24 (PD_1 data). |
Shunts are compulsory!
|
The connector for radio boards requires a specific format, which has been discontinued.
The CC3000 Evaluation Module and the Bluetooth Low Energy radio from Anaren are available on this format. |
The BoosterPack has its own BoosterPack.

Pins Map
Before plugging the BoosterPack onto the LaunchPad LM4F120 or TM4C123, check resistors R9 and R10 are populated, otherwise the I²C bus wouldn't be connected.

Conclusion
The Sensor Hub BoosterPack provides an amazing range of sensors, very close to those featured on the SensorTag, Bluetooth Low Energy excepted.
However, the BoosterPack relies on phased-out standards: the pins for the I²C port and the radio specific board format are no longer available. Maybe it's time for an update! |
