This circuit centers on the efficient STM32L4 microcontroller unit (MCU), orchestrating suspension data collection. The precision of the Suspension Tension Meter is attributed to the NAU7802 24-bit ADC, ensuring accurate recording of push-rod forces. Its high resolution captures subtle tension changes, aiding engineers in suspension fine-tuning. Real-time data transmission over the CAN bus enables adjustments during racing or challenging terrains, optimizing vehicle performance. The CAN interface serves as the data transfer backbone, facilitating seamless communication for real-time suspension adjustments, and enhancing handling on the track.
