The ADIS1613x, ADIS1636x, ADIS16375, ADIS16407 and ADIS1648x IMU products all use a 24-pin, dual-row, 1mm connector for their electrical interface. The mating connector for their interface supports surface-mount solder attachment but does not support direct attachment with ribbon cables. For those who are would like to connect these IMU and gyroscope products to an existing processor board, using a ribbon cable, the ADIS16IMU1/PCB provides a simple connector translation for this purpose.
Here is a picture of the contents that come with the ADIS16IMU1/PCB.

The ADIS16IMU1/PCBZ provides several sets of mounting holes that line up with mounting holes and tabs on the following products: ADIS1613x, ADIS1636x, ADIS16375, ADIS1640x and ADIS1648x products. Please see the following picture for device mounting hole locations.
The machine screws in the ADIS16IMU1/PCBZ kit are made out of stainless steel, which can have some moderate impact on magnetic fields, local to the IMU. For those who need the best performance out of their magnetometer solution in these IMUs, consider replacing these screws with those that will not impact the magnetic fields around the devices. We (ADI) are investigating new machine screws for future use.
Use the M2x0.4x16mm machine screws (provided in pink bag) for mounting these products to the ADIS16IMU1/PCBZ and set their torque for 20 inch-ounces. The yellow-highlights in the top-view picture illustrate the location of the mounting holes for these products.
WARNING: Remove the jumper from JP1 when using the ADIS16IMU1/PCB to evaluate these products.
Use the M2x0.4x4mm machine screws (provided in pink bag) for mounting these products to the ADIS16IMU1/PCBZ and set their torque for 20 inch-ounces. The pink-highlights in the top-view picture illustrate the location of the mounting holes for these products. For high-vibration environments, consider using more than 2 screws. Application Note AN-1045 offers some ideas on using more than two screws to attach this package style to a system frame.

Use the M2x0.4x16mm machine screws (provided in pink bag) for mounting these products to the ADIS16IMU1/PCBZ and set their torque for 20 inch-ounces. The blue-highlights in the top-view picture illustrate the location of the mounting holes for these products.
The mounting holes are presently tapped for use with M2x0.4mm. While the pre-tapped holes provide convenience in the mounting process, they also constrain the mounting hole location in a manner that can result in a translational force on the electrical connector. This violates one of the “best-practice” criteria in the product datasheets and can impact key bias stability behaviors. For those who want to preserve best performance, open the diameter of these holes to 2.85mm and use a washer/nut combination on the backside of the interface board to secure the ADIS1648x to its surface.
Here is an example of the ADIS16IMU1/PCBZ, with an ADIS16485AMLZ mounted to it.
Make sure that the connector pins are in alignment with J2 on the ADIS16IMU1/PCBZ, before pressing it into place.
Here is a close-up view, which shows the correct connector alignment.
This picture provides an example of the an incorrect connector alignment. Note that this view is on the EVAL-ADISZ board, not the ADIS16IMU1/PCBZ.
J1 is the electrical connector that provides direct access to power, ground and critical digital I/O pins on the devices. It is a 16-pin, dual-row, 2-mm pitch connector that support 1mm ribbon cable systems.
Here is the pin assignments for J1, which is the connector that will interface with an embedded processor board.
Check out the following link for ideas on how to make or purchase 16-pin, 1mm ribbon cables that can mate to J1 on the ADIS16IMU1/PCBZ.
