2. Purpose
This document describes the hardware and circuitry on the MPU-6000 and MPU-6050 (collectively
called the MPU-60X0) 9-Axis Evaluation (EV) Board. This EVB is used for evaluating the MPU-6000
and MPU-6050. 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 nine axes of motion sensing, comprised of:
Digital-output X-, Y-, and Z-Axis angular rate sensors (gyroscopes) with a user-
programmable full-scale range of ±250, ±500, ±1000, and ±2000°/sec
Digital-output tri-axis accelerometer with a programmable full scale range of ±2
g
, ±4
g
,
±8
g
and ±16
g
Digital-output tri-axis compass with a full scale range of ±1200µT
Data is measured using on-chip ADCs and 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 a USB interface.

3. MPU-6000 9-Axis EV Board Overview
The MPU-6000 9-Axis EV Board contains the MPU-6000 digital Motion Processing Unit and the AKM
compass. Additionally, i
t contains a number of „solder-across‟ jumper points that permit several circuit
configurations.
Please refer to Figures 1 & 5. The EV Board is populated on its top side only for ease of measurement
access. The 10x2 customer header connector (JP14) is designed to connect with the InvenSense ARM
Evaluation Board (INVARMEVB), which is a host microcontroller board useful for adapting the MPU-
6000 9-Axis EV Board to a personal computer via its USB port.
The 5x2 extension factory header (JP13) is intended for connecting additional devices to the EV Board,
such as a camera image stabilization processor, or a digital-output compass, etc. The 3-pin power
selection header (JP12) is used to select which voltage supply is fed to the MPU-6000. The 3-pin
VLOGIC selection header (JP6) is used to select between 3 V and VDD as the logic supply voltage.
