x-BIMU


LOW POWER, LOW LATENCY, WIRELESS IMU

The x-BIMU is a versatile IMU and AHRS specifically designed to interface to XBee-style wired and wireless communication modules. On-board sensors and algorithms to provide both inertial sensor data and a real-time measurement of orientation relative to the Earth

The x-BIMU is optimised to operate with 802.15.4 XBee wireless modules to achieve its best low-power and low-latency performance but is compatible with any serial-based interface (e.g. Bluetooth and serial breakout). A simple communication protocol uses either ASCII or binary packets and provides access to all settings through serial commands using any serial terminal. The generic C++ example demonstrates how to decode the serial stream on any host platform.

Sensors
Calibrated gyroscope (±2000°/s), accelerometer (±16 g) and magnetometer *
On-board AHRS algorithm *
Battery level measurement
Selectable data rates up to 256 Hz (128 Hz with 802.15.4 XBee)
Communication
Optimised for XBee 802.15.4 but compatible with any serial interface
ASCII or binary packet modes for simple integration with any software
Low-power features
13 mA stand-alone, 25 mA with XBee 802.15.4 using low-power settings
Sleep-timer and motion trigger wake up
On-board charging via USB (does not provide communication)
* The magnetometer is uncalibrated and cannot be used by the on-board AHRS algorithm.

x-BIMU Body Strap

The x-BIMU Body Strap combines with the x-BIMU Housing to allow the x-BIMU to be fastened to different points on a person’s body.

The body strap is comprised of three parts: a plastic bracket, a 50cm Velcro strap and a 10 cm Velcro strip. The x-BIMU Housing slots in the plastic bracket and is held in place by threading the 50 cm Velcro strap through the eyelets either side of the bracket as shown in the photos. The shorter Velcro strip can fastened on the underside for extra security. Excess material can be removed with scissors.

The plastic bracket is laser-cut from 5mm acrylic plastic. The CAD files for this part available on GitHub. The Velcro parts are cut from a reel of 25 mm width Velcro One Wrap.

Connection instructions

  1. Select 'Add new Bluetooth device' on your system
  2. Enter the passcode: "1234"
  3. The Bluetooth module will now appear as a serial port. Your system will open the connection each time the port is opened

x-BIMU Serial Breakout

The x-BIMU Serial Breakout is a carrier board for the x-BIMU that breaks out the serial interface pins to a header to simplify connection to other serial devices. The x-BIMU uses 3.3 V level serial and is 5 V tolerant. The serial breakout board incorporates an on-board low-dropout voltage regulator and can be powered from a 3.3 V to 5.5 V external supply. The header is compatible with sparkfun's FTDI Basic Breakout for connection to a USB host. The Arduino/C++ example demonstrates how to interface to the x-BIMU and decode the serial data stream.

Features

  • FTDI compatible 6-way header
  • 3.3 V and 5 V compatible
  • Optional hardware-flow control
  • Mounting holes

x-BIMU 802.15.4 XBee

This is the Digi XBee® 802.15.4 wireless module with built in PCB antennae. The x-BIMU is optimised to operate with this modules to achieve its best low-power and low-latency performance. The modules are supplied pre-programmed with Digi’s default factory settings and automatically configured according to the x-BIMU’s internal settings each time the x-BIMU is switched on.

The x-BIMU settings allow each x-BIMU using an XBee module to be configured to one of twelve wireless channels, the selected channel is indicated by the colour of the x-BIMU status LED. Each channel requires a separate XStick USB dongle to receive the data. Using a separate XStick for each channel enables the x-BIMU to achieve its low-latency, low-jitter, robust wireless performance.

Advanced users who have used XBee modules before may wish to reprogram the module using the Digi X-CTU software to create more complex network behaviour. For example, to have multiple x-BIMUs connected to a single XStick. Please refer to the x-BIMU user manual for details on how XBee settings can be modified without breaking compatibly with the x-BIMU.

x-BIMU 802.15.4 XStick

The Digi XStick® 802.15.4 is a wireless USB dongle compatible with 802.15.4 XBee modules. The x-BIMU is optimised to operate with these modules to achieve its best low-power and low-latency performance. The XStick is pre-programmed with settings to enable compatibility with the x-BIMU Terminal software and supplied with a page of coloured wireless channel stickers.

The x-BIMU settings allow each x-BIMU using an XBee module to be configured to one of twelve wireless channels, the selected channel is indicated by the colour of the x-BIMU status LED. Each channel requires a separate XStick to receive the data, the XStick channel is set using the x-BIMU Terminal. Using a separate XStick for each channel enables the x-BIMU to achieve its low-latency, low-jitter, robust wireless performance.

Advanced users who have used XBee modules before may wish to reprogram the module using the Digi X-CTU software to create more complex network behaviour.
