Overview:
I am creating a board that can track all the dynamics data for the next-gen car. This includes a board with connectors that will be used as a breakout and two separate boards with the sensors attached (IMU and hall-effect respectively). We want to track the dynamics data primarily for its usage within later simulations of car route optimization (plus it’s also nice to have). This data will also be displayed on a real-time dashboard later (courtesy of Pablo).
Special Parts:
IMU: 6-axis inertial measurement unit (IMU) with embedded sensor fusion, I3C, OIS/EIS for smart applications (LSM6DSV)
This IMU takes up minimal power (though it’s not super important for sensors) and supports both I2C and SPI.
It has significant motion detection, a fast processing rate, high precision, and pretty much everything we need to track motion.
Hall-Effect: 14-bit, Digital, Contactless Angle Sensor with ABZ Incremental & PWM Outputs (MagAlpha MA730)
For a good value price, it supports high speeds up to 60,000 RPM at a high precision rate.
It runs SPI, supports extra configs, and can be mounted in a few different orientations.
LDO (3.3 -> 1.8): 50-mA, 24-V, 3.2-μA Quiescent Current, Low-Dropout Linear Regulator (TPS715)
Part of a family of LDOs that output various voltages and good documentation
The datasheet is for the general part but we can order the specific part from Mouser

Design Justification/Considerations:
I used a main board connected to a bunch of peripherals to allow for flexibility in mounting
Nano-fits (Molex) were used to save space as we want something as compact as possible
I2C is not meant for very long distances, but after checking the frequency of the sensor (960Hz) against the clock (400KHz) it seemed to be ok. However, if we start getting signal degradation, we can slow down the clock
Over a long distance, there may be some voltage drop, but the power is so low that it should be negligible. For a 24 AWG, 4ft wire, and .65mA current, the drop-off should be around 20 microvolts, orders of magnitude below .05 volts.
CS must be connected to VDD for control over I2C
Mounting:
Hall Effect (TBD):
IMU:
Somewhere on the upright, most likely on the top face.
*The upright is subject to change, meaning these mounting configurations could be invalid.
