GENERAL DESCRIPTION
The iMEMS® ADXL345 inertial sensor evaluation system
is an easy-to-use evaluation tool targeting bench or desktop
characterization of Analog Devices, Inc., inertial sensor products.
The system consists of the inertial sensor evaluation board (ISEB),
or main board, and a satellite board for any Analog Devices
inertial sensor product. The ISEB connects directly to a PC via
its USB, where the USB connection provides both power and
communications to the board. The ISEB then connects to the
satellite board through a ribbon cable. This cable allows the
satellite to be easily manipulated for testing or for being separately
placed into an environmental chamber for temperature or
humidity testing. Separating the boards mitigates corruption
of data due to the temperature and humidity effects of other
components. The ISEB is a universal main board and is intended to be used
with various satellites of Analog Devices inertial sensors, including
analog and digital accelerometers, as well as gyroscopes. The
different products are evaluated by means of separate GUIs that are
customized for performance and characterization measurements
relevant to the inertial sensor being evaluated.
The EVAL-ADXL345Z-M system contains the ISEB and the
EVAL-ADXL345Z-S satellite. Also included is a USB A to
Mini-B cable to connect the ISEB to a PC and an 18-inch,
20-pin ribbon cable to connect the ISEB to the satellite. A CD
is also included with the necessary drivers and executables to
use the system and to quickly begin evaluating the ADXL345.
