OpenIMU335RI Eval Kit

OpenIMU335RI Evaluation Kit Introduction

The OpenIMU evaluation kit is a hardware platform used to evaluate the OpenIMU335RI inertial navigation system and develop various applications based on this platform. A difference to standard part is that a JTAG (SWD) 20-pin header is brought out for code development. It is supported by Aceinna Navigation Studio, which enables the user to quickly evaluate the part. The Components section below details the contents of the kit.

Note

An external DC power supply is required. The power supply must be able to provide 100mA at 9VDC to 32VDC.

OpenIMU335RI Evaluation Kit components

OpenIMU335RI Evaluation Kit fixture and JTAG header board

• The OpenIMU335RI unit with JTAG header board are mounted on the test fixture. The JTAG header provides a means to debug/upload applications to the evaluation unit.

  

ST-Link debugger

• The ST-Link V2 programmer / debugger is a standard JTAG SWD debugger provided by STMicroelectronics company. It is used for in-system debugging/uploading of applications via SWD interface.

  

OpenIMU335RI Breakout Cable

• An included cable provides a means of connecting the unit to a PC via RS232 interface, connecting the unit to the CAN bus, and powering the unit. The next table shows the connector pin assignments of the supplied cable.

  Signal Name	Unit Connector	RS232 Connector	CAN Connector	Power Wires
  GND	3	5		Black
  VIN	6			Red
  RS232 TX	5	2
  RS232 RX	4	3
  CAN H	1		7
  CAN L	2		2

OpenIMU335RI Connector

The connector of the breakout cable is shown in the following image. See the notes below for details of how to connect to and disconnect from the OpenIMU335RI.

The pin numbers are as follows:

Note

To connect the cable to the OpenIMU300RI evaluation unit:

• Align the keys on the unit and the cable connector.
• Push the 6-pin cable connector into the unit connector until lock clicks.
• If an extra lock is required - push the red latch under the black latch. This prevents the disengagement button from being depressed.

Note

To disconnect the cable from the from OpenIMU335RI evaluation unit:

• If engaged, pull the red latch away from the connector toward the cable.
• Push down on the black disengagement button in the middle of the connector.
• Pull the cable connector away from the unit.

OpenIMU335RI Evaluation Kit Setup

To get started with the OpenIMU335RI evaluation kit connect the breakout cable to the evaluation kit.

• Connect the RS232 connector of the cable to a PC if you wish to evaluate using Aceinna Navigation Studio.
• To evaluate the part using the CAN interface simply connect to either a CAN analyzer, or network, and refer to the CAN Port Interface Definition section of the user manual.
• Connect RED (+) and BLACK (GND) wires to an external power supply (9 - 32V, 0.1A)

Refer to the Aceinna Navigation Studio website where there is documentation on how to:

• Download a PC server application that will allow you to evaluate the part over the RS-232 interface using the Chrome® web browser: https://developers.aceinna.com/devices/connect
• Update the firmware on the OpenIMU335RI using one of Aceinna’s pre-compiled applications: https://developers.aceinna.com/code/apps
• Install the OpenIMU programming environment for user code development: https://developers.aceinna.com/docs/install

The following activities are addressed in the Tools section:

• How to uload an App via JTAG
• Debugging with the PlatformIO Debugger and JTAG Debug Adapter
• Graphing & Logging IMU Data using the Acienna Navigation Studio
