All rights reserved. MPU-9150 EV Board User Guide Document Number: AN-MPU-9150EVB-00 Revision: 1.0 Release Date: 05/11/2011 2. Purpose This document describes the hardware and circuitry on the MPU-9150™ 9-Axis Evaluation Board (EVB). This EVB is used to evaluate the MPU-9150. The document covers (1) how to apply the EVB to a larger system, (2) understanding key signals and circuit functions, (3) hardware jumper settings, and (4) port connector descriptions. 2.1 Usage This evaluation board is used to demonstrate InvenSense’s MPU-9150 for 9-Axis motion detection and measurement. These 9 axes are comprised of the following: • • • Digital-output X-, Y-, Z-Axis angular rate sensors (gyroscopes) with a user-programmable fullscale range of ±250, ±500, ±1000, and ±2000°/sec Digital-output X-, Y-, Z-Axis accelerometers with a programmable full scale range of ±2g, ±4g, ±8g and ±16g Digital-output X-, Y-, Z-Axis magnetometer (compass) with a full scale range of ±1200µT Nine axis motion is measured using on-chip ADCs and transmitted through the MPU-9150’s primary I²C interface. The user can use the primary I²C serial communications interface for standalone testing of the evaluation board. Alternatively, by connecting the EVB to the InvenSense ARM Evaluation Board (INVARMEVB), the user can connect the evaluation board to a host Windows PC via a USB interface. Figure 4 shows the MPU-9150 9-Axis Evaluation Board and the INV-ARMEVB connected together. When this evaluation board is connected to a host Windows PC through the INV-ARMEVB’s USB interface, the MPU-9150’s motion processing capabilities can be demonstrated through motion related application software. InvenSense provides a software package for evaluating the MPU-9150 by using the MPU-9150 EV Board. The InvenSense PC Demo Software Package, along with the Installation and User Guide for PC Demo Software for Windows can be found in the InvenSense Developers Corner (http://www.invensense.com/developers/). The MPU-9150 Evaluation Board is designed to give the user easy access to key signals and configuration pins. 2.2 Related Documents The following resources are recommended for a more comprehensive understanding of the components and systems described in this User Guide.

MPU-9150 9-Axis EV Board Overview The MPU-9150 9-Axis EV Board is a fully tested evaluation board for the MPU-9150 digital Motion Processing Unit™ (MPU™). It contains a number of ‘solder-across’ jumper points that permit several circuit configurations. For ease of measurement access, the EV Board is populated only on its top side. Figure 1 shows each of these connectors. The 10x2 Customer Header Connector (JP12) is designed to connect with the InvenSense ARM Evaluation Board (INV-ARMEVB). The INV-ARMEVB is a host microcontroller board used to connect the MPU-9150 9-Axis EV Board to a host Windows PC via a USB port. The 5x2 Extended Factory Connector (JP11) is used to connect additional host application devices to the EV Board. For instance, a camera image stabilization processor can be connected to the MPU-9150 by using JP11. Please note that such devices should act as a master to the MPU-9150. The 3-pin Power Selection Header (JP8) is used to select which voltage supply is fed to the MPU-9150. The 3-pin VLOGIC Selection Header (JP4) is used to select between 3 V and VIN as the logic supply voltage. For further information regarding the power supply connections, please refer to Section 6.

The MPU-9150 has an embedded 3-axis MEMS gyroscope, 3-axis MEMS accelerometer, 3-axis MEMS magnetometer and Digital Motion Processor™ (DMP) hardware accelerator engine. 9-axis MotionFusion™ combines acceleration and rotational motion plus heading information into a single data stream for an application. The MPU-9150’s primary I²C interface is used to communicate with the system processor. 2 The MPU-9150’s auxiliary I C port is used to communicate with third party digital sensors such as pressure sensors, but is not supported on this USB Reference Board. The MPU-9150 uses InvenSense’s proprietary MEMS technology to produce a functionally complete, low-cost motion processor. All required conditioning electronics are integrated into a single package measuring 4mm x 4mm x 0.95mm. It incorporates X-, Y-, and Z-axis low-pass filters and an EEPROM for on-chip factory calibration of the sensors. A built-in Proportional-To-Absolute-Temperature (PTAT) sensor provides temperature compensation information. The product is lead-free and Green Compliant. Figure 2 shows the MPU-9150’s pins as well as its motion detection directions. Note: The orientation and polarity of the magnetometer detection axes differ from those of the gyroscope and accelerometer.

Power Supply Connections The JP4 VLOGIC Selection Header and JP8 Power Selection Header are 3 header-pin plug-in jumpers which allow users to select between the on-board LDO (Low-dropout voltage regulator) and an external DC supply for powering the MPU-9150. Please refer to Sections 6.1 and 6.2 for further information. The on-board 3.0V LDO is a low-noise LDO. Its output is labeled as 3V0 in the schematic diagram in Section 4. Using this on-board LDO will assure that the gyroscope, accelerometer, and magnetometer performance will meet intended specifications. The raw VIN line is generally selected to power the chip when designing and evaluating an embedded platform, where the host processor and related electronics need full control over the motion processing chipset’s power supply. When the on board LDO 3V0 power source is used, the external VIN must be provided with at least 3.7V in order to ensure that the LDO works properly. If the user provides the VIN with 5V, JP4 and JP8 must be set as “1-2 short”. This is because the MPU9150’s VDD and VLOGIC operation range is 2.1V to 3.6V. 6.1 JP4 – VLOGIC Selection Header The 3-pin VLOGIC Selection Header (JP4) is used to select between 3 V and VIN as the logic supply voltage. Table 3 below describes the details of voltage selection for JP4. Table 3: JP4 - VLOGIC Selection Header 6.2 JP4 Pin Number Signal description 1-2 short MPU-9150 VLOGIC = 3V (Taken from LDO. VIN must be greater than 3.7 V) 2-3 short MPU-9150 VLOGIC = VIN (Taken from external source) JP8 – Power Selection Header The 3-pin Power Selection Header (JP8) is used to select which voltage supply is fed to the MPU-9150.

It carries the FSYNC signal from the camera platform to the EV Board. The FSYNC signal is used to synchronize the MPU-9150 serial bus transfer with the master timing set by the camera system. The MPU-9150 accepts the FSYNC input from JP11 pin-10 or JP12 pin-21. There is no external pull-up termination for the FSYNC line. For further information regarding MPU-9150’s handing of the FSYNC signal, please refer to the MPU9150 Product Specification document, as well as the MPU-9150 Register Map and Register Descriptions document. 7.4 Serial bus Levels, Speeds and Terminations The serial bus level is VDDIO. The MPU-9150 supports I²C communication up to a clock rate of 400kHz. The I²C bus open drain pull up resistors are connected to VDDIO.
