x-IMU


OUR ORIGINAL VERSATILE IMU BOARD

The x-IMU was designed to be the most versatile Inertial Measurement Unit (IMU) and Attitude Heading Reference System (AHRS) platform available. Its host of on-board sensors, algorithms, configurable auxiliary port and real-time communication via USB, Bluetooth or UART make it both a powerful sensor and controller. The on-board SD card* , battery charger (via USB), real-time clock/calendar and motion trigger wake up also make the x-IMU an ideal standalone data logger.

The x-IMU GUI can be used to configure settings, view real-time sensor data, perform calibration and export data to user software; e.g. Microsoft Excel. The x-IMU MATLAB library provides all the tools required to import, organise and plot data in MATLAB. User software can be developed using the x-IMU API.

* SD-card, USB cable, Bluetooth dongle not included.

Please see NGIMU as replacement

x-IMU Housing

The x-IMU housing encloses the x-IMU and a 1000 mAh Lithium Polymer Ion battery while still providing access to the USB socket, SD card, command button and auxiliary port. The x-IMU's LED are visible through the translucent plastic. The compact design of the housing does not feature mounting brackets, instead the large flat underside was designed to be compatible with adhesive-based solutions such as the x-IMU Velcro Strap and x-IMU Dual Lock Strips.

Specification

  • Dimensions: 57 × 38 × 21 mm
  • Weight: 49 g (including x-IMU and battery)

x-IMU Velcro strap

The x-IMU Velcro Strap is a versatile and simple solution for users wishing to secure an x-IMU to the legs, arms or torso or human subject. The Velcro strap has hooks on one side and loops on the other enabling it to fasten around any circumference. The Velcro adhesive pads are of the same dimensions as the x-IMU Housing and can be be mounted at any point on the strap. The 1 m Velcro strap can be cut into two shorter lengths so that one pack can be used to secure two x-IMUs.

Pack includes

  • 1× Velcro strap (1 m × 50 mm)
  • 2× Velcro adhesive pads (50 mm × 35 mm)

Price: £5.00

x-IMU Dual Lock Strips

The x-IMU Dual Lock Strips are a versatile and lost-cost solution to secure an x-IMU to just about anything. The strips are one of the strongest 3M™ Dual Lock™ variants, SJ3560. They are highly durable enabling the x-IMU to be attached and detached hundreds of times.

Each strip is identical with a no-residue, pressure sensitive VHB™ adhesive on one side and the Dual Lock mushroom shaped stems on the other. The mushroom shapes mate to create a strong, almost rigid connection; ideal for securing an inertial sensor. The 50 mm × 25 mm area of each strip matches the profile of the x-IMU Housing to provide the maximum contact area. Each pack contains 2 strips.

x-IMU RGB LEDs

The x-IMU RGB LEDs connect directly to the auxiliary port of the x-IMU and can be driven by three PWM signals to create any colour light. The module consists of a driver IC and three high brightness, defused lens RGB (Red, Green, Blue) LEDs. The RGB channels are controlled by the auxiliary port channels AX0, AX2, and AX4 in either digital I/O mode or PWM output mode.

This module was originally created for use with prototype data gloves that incorporated the x-IMU to allow the host software to give real-time feedback to the user.
