Ultra small robust 6-DOF IMU weighs less than 1 gram


The M-V340 6-DOF inertial measurement unit (IMU) from Epson has three axes of gyroscopes and accelerometers, plus provides built-in support for two widely-used industrial and aerospace interfaces: SPI and UART protocol. At just 12x10x4mm in size, the M-V340 IMU is the smallest high-performance IMU on the market today. The M-V340 weighs less than 1 gram, and consumes just 16.5 mA of current, and is capable of withstanding high vibration and shock.

A variety of calibration parameters are stored in a memory of the IMU, and are automatically reflected in the measurement data being sent to the application after the power of the IMU is turned on. With a general-purpose SPI/UART supported for host communication, the
M-V340 reduces technical barriers for users to introduce inertial measurement and minimizes design resources to implement inertial movement analysis and control applications.
