OpenIMU300RI Evaluation Kit Introduction

The OpenIMU evaluation kit is a hardware platform used to evaluate the OpenIMU300RI inertial navigation system and develop various applications based on this platform. It is supported by the Aceinna Navigation Studio, which provides easy access to the features of the OpenIMU300RI and explains how to integrate the device in a custom design. The Components section below provides the contents of the kit.

Note

An external DC power supply is required. The power supply must be able to provide 400mA at 4.9VDC to 32VDC.

The cable shown in the Evaluation Kit figure may look different than the cable that will be provided with the Evaluation Kit

OpenIMU300RI Evaluation Kit components

OpenIMU300RI unit

OpenIMU300RI is 9 DOF (degrees of freedom) fully calibrated inertial unit. It is used as the base for development custom inertial navigation applications.

OpenIMU300RI Evaluation Kit fixture and JTAG header board

The OpenIMU300RI unit with JTAG header board are mounted on the text fixture. The JTAG header provides means to debug/upload applications on evaluation unit.

ST-Link debugger

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

OpenIMU300RI Breakout Cable

An included cable provides means of connecting unit to PC via RS232 interface, connecting unit to the CAN bus and powering up unit.

OpenIMU300RI Evaluation Kit Setup

To set up OpenIMU300RI evaluation kit you’ll need to perform next steps:

  1. Install PC tools.
  2. Unpack OpenIMU300RI evaluation kit.
  3. Connect provided cable to OpenIMU300RI evaluation unit (see notes below).
  4. Connect cable connector marked “RS232” to the PC serial port or to UCB-to-Serial adapter.
  5. Connect cable connector marked “CAN” to the CAN bus or to the CAN traffic monitoring unit (like Vestor or Komodo or other).
  6. Connect ST-Link debugger to the PC via USB cable. Make sure that ST-Link device appeared in “Device Manager”.
  7. Connect 20-pin connector on OpenIMU300RI evaluation unit to ST-Link debugger using provided 20-pin flat cable.
  8. Connect RED (+) and BLACK (GND) wires to external power supply (5 - 32V, 0.1A)
  9. Turn ON power supply.

Now you are ready to debug and test your application.

  • The following activities are addressed in the “Tools/Development Tools” section:
    • Download App with JTAG
    • Debugging with PlatformIO Debugger and JTAG Debug Adapter
    • Graphing & Logging IMU Data using the Acienna Navigation Studio

Note

The RS232/CAN/Power cable shown in the image is similar to the cable that will be supplied with the kit. It is for information only.

Note

The following directions are applicable for connecting cable to 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 required - push the red latch under the black latch. This prevents the disengagement button from being depressed.

Note

The following directions are applicable for disconnecting cable from OpenIMU300RI 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.
