Y-AXIS ACC. Z-AXIS ACC. X-AXIS INCL. Y-AXIS INCL. Z-AXIS INCL. GYRO DRIVE + ADC + LPF GYRO DRIVE + ADC + LPF GYRO DRIVE + ADC + LPF STIM300 is an IMU consisting of 3 high accuracy MEMS-based gyros, 3 high stability accelerometers and 3 high stability inclinometers in a miniature package. Each axis is factory-calibrated for bias, sensitivity and compensated for temperature effects to provide high-accuracy measurements in the temperature range -40°C to +85°C. The unit runs off a single +5V supply. STIM300 communicates via a standard high-level RS422 interface. The use of a 32-bit RISC ARM microcontroller provides flexibility in the configuration, like choice of output unit, sample rate, low pass filter ‒3dB frequency and RS422 bit-rate and protocol parameters. All configurable parameters can be...
