ADIS16IMU1/PCBZ Breakout Board Wiki-Guide

OVERVIEW

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.

IMU/GYROSCOPE MOUNTING HOLES

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.

MACHINE SCREWS IMPACT ON LOCAL MAGNETIC FIELDS

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.

ADIS16133, ADIS16135, ADIS1636 Mounting

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.

ADIS16360, ADIS16362, ADIS16364, ADIS16365, ADIS16367, ADIS16400, ADIS16405, ADIS16407 Mounting

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.

WARNING: Remove the jumper from JP1 when using the ADIS16IMU1/PCBZ to evaluate these products.

ADIS16375, ADIS16480, ADIS16485, ADIS16488 Mounting

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.

Mounting Holes

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.

INTERFACE CONNECTOR

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.

Pin Assignments

Here is the pin assignments for J1, which is the connector that will interface with an embedded processor board.

Ribbon Cable Options

Connector Part Numbers

This section is specific information about the connectors on the ADIS16IMU1/PCBZ. These connectors can be ordered thru a number of different electronic distributors including but not limited to:

The 1st picture below is J1 P/N A3-16PA-2SV(71)Manufacturer: Hirose. The 2nd picture is an alternative P/N TMM-108-01-G-D-SM Manufacturer: Samtec. The J1 connector is a 16 pin dual row part with a 2mm pitch and plugs into the EVAL-ADIS J1 connector.

Manufacturer: Hirose A3-16PA-2SV(71)

Manufacturer: Samtec TMM-108-01-G-D-SM

The J2 connector on the ADIS16IMU1/PCBZ is where the device plugs into directly or thru a flex cable dependent on the specific part being evaluated. The J2 connector is a 24 pin 1mm Samtec connector P/N CLM-112-02-L-D shown below.
