SENtral M&M
Motion-Tracking & Measurement Modules
General Description
PNI’s SENtral M&M motion-tracking and
measurement modules provide highly
accurate heading and orientation data, in a
small, low-power-consumption, and easy-tointegrate package. A module incorporates
the SENtral motion coprocessor, a
magnetometer, an accelerometer, and a
gyroscope, with different SENtral M&M
versions comprising different model sensors.
Unlike other inertial measurement units
(IMUs) requiring unexpected and extensive
sensor fusion algorithm development and
sensor calibration work, the Sentral M&M
modules are pre-engineered to provide the
highest accuracy motion tracking and
heading measurement. And this is obtained
at a fraction of the power consumption of
any other solution on the market.
The SENtral M&M comes ready to integrate
into a user’s system. Designed with SMT
bonding in mind, the pins are on an
industry-standard 3 mm pitch. The on-board
EEPROM contains SENtral’s configuration
file and this automatically uploads into
SENtral RAM when powered up.
Communication is via I2C protocol.
With the SENtral M&M modules you can
quickly and easily incorporate industryleading motion-tracking and orientation
measurement in your mobile device. We’re
sure you’ll be impressed.
Features
All-in-one motion & orientation tracking
module, incorporates the SENtral motion
coprocessor, 3-axis gyroscope, 3-axis
accelerometer, and 3-axis magnetometer.
Low power consumption.
11x11 mm footprint and SMT design for
ease of integration into a user’s system
Multiple test points for debugging and
evaluating performance.
Multiple versions with different sensors.
Applications
Personal Navigation & LBS
Gaming & Augmented Reality
Movement Science & Fitness

1. SENtral’s I C Host Interface supports Standard, Fast, Fast Plus, and High Speed Modes.
High Speed Mode (3400 kHz) is supported with a reduced range of V DD and bus
2
capacitance. SENtral’s I C sensor bus interface supports Standard, Fast, and Fast Plus
Modes. Pass-Through state, which connects the sensor bus and host bus, supports
Standard and Fast Modes.
