CHR-UM6-LT Orientation Sensor
The UM6-LT ultra-miniature orientation sensor from CH Robotics is an OEM version of their UM6 orientation sensor, providing equivalent functionality without the enclosure or connectors. Like the UM6, it uses rate gyros, accelerometers, magnetic sensors, and an on-board 32-bit ARM Cortex processor to compute sensor orientation 1000 times per second. Sensor orientation is reported using either quaternions or Euler angles over a TTL serial interface at user-customizable rates.

The UM6-LT ultra-miniature orientation sensor—also known as an Attitude and Heading Reference System, or AHRS—from CH Robotics is an OEM version of their UM6 orientation sensor. Like the UM6, it uses rate gyros, accelerometers, magnetic sensors, and an on-board 32-bit ARM Cortex processor to estimate the absolute sensor orientation 1000 times per second. Sensor orientation is reported using either quaternions or Euler angles over a TTL serial interface at user-customizable rates. A USB-to-serial adapter can be used to connect the IMU to a computer running the free CH Robotics Serial Interface PC application, which allows for easy data visualization, board calibration, and UM6-LT settings configuration.
The UM6-LT is functionally identical to the UM6 (it uses the same firmware and works with the same PC software). The only difference is that the UM6-LT lacks the UM6’s enclosure and 4-pin connector. Please see the UM6 product page or UM6/UM6-LT datasheet (552k pdf) for board specifications and usage information.
The CHR-UM6-LT sensors in our current stock do not have the latest firmware version, which is required to support GPS communication; however, they can be reprogrammed with the UM2B firmware using the CH Robotics Serial Interface or with this process described on the CH Robotics forum.
We carry several inertial measurement and orientation sensors. The table below compares their capabilities:

The UM6-LT is a pin-compatible replacement for the CHR-6dm AHRS sensor, which has been discontinued, so it can be physically swapped directly into systems that use the CHR-6dm. However, the UM6-LT uses the UM6 communication protocol, not the CHR-6dm protocol, so such a swap will require software modification.

This old-timey truck sure is pretty to look at, but it\'s not just for show. The Ugears Pickup Lumberjack is a working truck with a job to do, and that\'s hauling wood (or hay bales, or work tools—whatever you can imagine)! Based on the popular 1959 Chevrolet 3100, the DIY wooden model features a 1m x 7mm spring motor (same as the powerful Ugears Drift Cobra) allowing the Pickup to travel up to 6 meters and haul loads of 400 - 450 g in the truck bed. The winding knob is stylized to resemble a custom open top air filter emerging from the hood. Lift the hood to reveal the beautiful V8 engine firing away! UGears 70171
