2. Purpose
This document describes the hardware and circuitry on the MPU-3000™ & MPU-3050™ 3-Axis
Evaluation (EV) Board. It covers applying the EV board to a larger system, understanding key signals
and circuit functions, hardware jumper settings, and port connectors.
2.1
Usage
This evaluation board provides three axes of motion sensing, comprised of:
X-, Y- and Z-Axis gyros with ±250°/sec, ±500°/sec, ±1000°/sec, ±2000°/sec selectable full-scale
range.
Digital data measured using on-chip ADCs, is transmitted over I²C or SPI interfaces.
The Evaluation board may be used by itself using SPI or I²C serial communications interfaces.
Alternatively, it may be connected to InvenSense‟s ARM Evaluation Board (INVARMEVB) for
connectivity to a host computer using USB interface.

3. MPU-3000 & MPU-3050 3-Axis EV Board Overview
The MPU-3000 & MPU-3050 3-Axis EV Board contains the MPU-3000 or MPU-3050 Digital Motion
Processing Unit. It contains a number of „solder-across‟ jumper points that permit several circuit
configurations.
Refer to Figure 1. The EV Board is populated on its top side only for easy of measurement access. The
10x2 customer header connector is designed to connect with the InvenSense ARM Evaluation Board
(INVARMEVB), which is a host microcontroller board useful for adapting the MPU-3000 & MPU-3050 3Axis EV Board to a personal computer via its USB port.

MPU-3000 & MPU-3050 Key Function and Pin-outs
The MPU-3000 & MPU-3050 EVB is a fully-tested evaluation board, providing for quick evaluation of the
MPU-3000 & MPU-3050‟s X- , Y- , and Z-axis angular rate gyroscope. The MPU-3000 & MPU-3050
use InvenSense‟s proprietary MEMS technology with vertically driven vibrating masses to produce a
functionally complete, low-cost motion sensor. All required conditioning electronics are integrated into a
single chip measuring 4 x 4 x 0.9mm. It incorporates X- , Y- and Z-axis low-pass filters and an
EEPROM for on-chip factory calibration of the sensor. Factory trimmed scale factors eliminate the need
for external active components and end-user calibration. A built-in Proportional-To-AbsoluteTemperature (PTAT) sensor provides temperature compensation information. The product is lead-free
and Green Compliant.

Power Supply Connections
JP2 and JP7 are 3 header-pin plug-in jumpers which allow users to select between on-board LDO
and external DC supply to the MPU-3000 & MPU-3050. For details, please refer Table 2. Power
Selection Jumpers.
The on-board 3.0V LDO (Low-dropout voltage regulator) is a low-noise version with stable enabledisable profile. Its output is called 3V0 on the schematic, and using it will assure that the gyroscope
and accelerometer performance will meet intended specifications.
Selecting the raw Vcc line to power the chip is generally done while designing and evaluating an
embedded platform, where the host processor and related electronics needs full control over the
motion processing chipset‟s power supply.
When user intends to use on board LDO 3V0 power, external Vcc must be provided with higher than
3.7V to ensure that the LDO works properly.
If user provides Vcc with 5V, JP2 and JP7 must be set as “1-2 short”. MPU-3000 & MPU-3050 VDD
and VLOGIC operation range is 2.1V to 3.6V.

Connecting the FSYNC Line
The FSYNC line is intended for use in a camera‟s image-stabilization system. It is an input from the
camera platform to the EV Board, and is intended to synchronize the MPU-3000 & MPU-3050‟s
serial bus transfer with the master timing set by the camera system. FSYNC can originate from the
host processor via JP8 pin-21, or from JP6 pin-10. There is no external pull-up termination for the
FSYNC line.
