Description

Key Design Points

• High performance STM32H743 Processor with more computing power & RAM
• New cost-effective design in a small form factor
• IMU redundancy with sensor technology from Bosch® & InvenSense®
• Integrated vibration isolation system to filter out high frequency vibration and reduce noise to ensure accurate readings
• IMUs are temperature-controlled by onboard heating resistors, allowing optimum working temperature of IMUs
• Hardware switchable 3.3V or 5V PWM signal mode (requires opening the casing)
