1OVERVIEW
The TDK SmartMotion DK-UNIVERSAL-I is a comprehensive development system for TDK InvenSense Motion
Sensor devices. The platform designed around the Microchip SAM G55 MCU can be used by customers for rapid
evaluation and development of InvenSense sensor-based solutions. The platform integrates an on-board
Embedded Debugger so external tools are not required to program or debug with the SAM G55 MCU. Each
InvenSense motion sensor has its own unique development kit (DK).
The TDK SmartMotion DK-UNIVERSAL-I comes with the necessary software, including an InvenSense Motion Link, a
GUI-based development tool, and embedded Motion Drivers (eMD) for InvenSense motion sensors.
Embedded Motion Drivers (eMD) consists of a set of APIs to configure various aspects of the platform including
motion sensor parameters such as full-scale range (FSR), output data rate (ODR), low-power or low-noise
mode, and sensor interface to host (I2C, SPI). eMDs will also provide the following enhanced motion functions that
run on the MCU:
•Sensor Fusion
•Accelerometer and Gyroscope Calibration
•Android Functions: Game Rotation Vector, Gravity, Linear Acceleration
Motion Link is a GUI-based development tool included with the platform. It can be used to capture and
visualize the sensor data from the motion sensor.
The platform supports Atmel Studio and is compatible with Microchip Xplained Pro Extension boards. The
Xplained Pro extension series evaluation kits offer additional peripherals to extend the features of the board and
ease the development of customer designs.
The TDK SmartMotion Development Kit (DK) DK-UNIVERSAL-I supports multiple types of TDK IMUs and pressure
sensors.

JUMPER
DESCRIPTION
J1
The J1 is used to select which sensor will be connected to the SAMG55 master I2C. Only two jumper shunts
are allowed.
Jumper shunts on pin-1/2 and 3/4: IMU Sensor primary I2C is connected to SAMG55 I2C master
Jumper shunts on pin-5/6 and 7/8: Other Sensor I2C is connected to SAMG55 I2C master. In this
configuration TDK IMU Sensor is connected to SAMG55 SPI master.
J2
The J2 is for board power source selection. Only one jumper shunt is allowed.
Jumper shunt on pin-1/2: board power is from EDBG USB on J500
Jumper shunt on pin-3/4: board power is from FTDI USB on CN6
Jumper shunt on pin-5/6: board power is from SAMG55 USB on J30
J3

4ADVANCED INFORMATION
4.1. UPDATING SAMG55 FIRMWARE HARDWARE USER GUIDE
The TDK SmartMotion Development Kit DK-UNIVERSAL-I is compatible with Microchip’s SAMG55 Xplained Pro for
updating and flashing the firmware. Follow this link to download the Atmel Xplained Pro user guide, starting from
page 5:
http://www.atmel.com/Images/Atmel-42389-SAM-G55-Xplained-Pro_User-Guide.pdf
Connect the EDBG (Atmel Embedded Debugger) USB port with USB cable to PC.
4.2. TDK SENSOR TO SAM G55 MCU CONNECTION
The DK-UNIVERSAL-I is the development kit for DB (sensor daughter board) and EVB (sensor evaluation board).
There is no sensor mounted on the DK-UNIVERSAL-I board. CN1 for EVB and CN4/CN5 for DB are mounted on
board for people to evaluate sensors (on EVB, DB, or standalone) separately. Figure 4 shows the pin out for CN1,
where an external EVB can be mounted.
Figure 4. Pin out of CN1 (Connector to EVB)
4.3. CONNECTING OTHER SENSORS
Third party sensors can be connected to the same SAM G55 MCU I2C bus with TDK sensor through DB, assuming it
has a different slave address.
CN2/CN3 are designed for other sensor DB plug in. It only supports I2C, not SPI.

(PB8/9)
TDK sensor is connected to this master I2C. On board sensor slave address =
0x69. Sensors on DB and EVB have slave address = 0x68.
SPI5
(PA05/PA11/12/13/14)
The SPI5 master is connected to TDK IMU sensor.
On board IMU /CS = PNCS1, EVB/DB IMU /CS = PNCS0.
GPIO (INTs)
PB03/PB15/PA30/PA20/PA15
The GPIOs are used for sensor interrupt inputs and other intelligent functions.
Refer to the table in Figure 5.
TW4 (I2C)
The master I2C communicates with EDBG MCU slave I2C.
UART6
The UART6 is used for EDBG DGI-UART interface.
UART7
The UART7 is used for EDBG CDC-UART interface.
