UM6 Orientation Sensor (CHR-UM6)

Produktbeschreibung

Kleines IMU System von CH Robotics mit einem Cortex-M3 Mikrocontroller.



The UM6 Ultra-Miniature Orientation Sensor uses rate gyros, accelerometers, magnetic sensors, and an onboard 32-bit ARM Cortex processor to estimate sensor orientation at 500 Hz. Sensor orientation is reported using either quaternions or Euler Angles over a TTL UART at user-customizable rates.

The UM6 was designed specifically to be easy to use - an external enclosure protects sensitive electronics, and connectors make it easy to interface with the sensor without making solder connections to the sensor itself. Two 12-pin female connectors on the underside of the UM6 allow the sensor to be plugged directly into a host system, removing the need to run wires to enable the sensor to communicate.

Expansion Boards and Accessories

• Serial Breakout Board
  The UM6 Serial Breakout Board allows the UM6 Orientation Sensor to be connected directly to a computer via an RS-232 serial port (or through a USB-serial converter). The Serial Breakout Board is a highly recommended accessory to the UM6.
• UM6 Data Cable
  The UM6 data cable provides convenient access to the power and UART lines on the UM6.
• UM6 Arduino Shield - Coming Soon
  The UM6 Arduino Shield allows the UM6 to be connected directly to Arduino devices.
• UM6 Flash Datalogger - Coming Soon
  The UM6 Flash Datalogger allows high-rate data from the UM6 to be logged to an onboard SD Flash card.
