Here’s what the Flux documentation says about private vs public projects:
“Projects and parts are considered private when they can be accessed only by you or individually selected people. To keep projects private, the option ‘PRIVATE - Only you can view an edit’ must be selected in the share dialog. You can still add people individually through the Advanced menu.
To quickly find out if a project is private, look for a padlock icon next to the share button.
Note: new projects are private by default.” Source

I can’t inspect the attached file or project settings right now because AI tool execution is unavailable due to no available ACUs. So far in this session, we clarified your concept: 16 non-alternating 5 mm magnets on an 80 mm pitch circle, omnipolar Hall sensors for quadrature/direction/repetition counting, a separate 12 × 25 mm sensor PCB, and an S-type load cell read by an ADS1232.
What remains:
  • Check the pasted attachment/project share settings to confirm whether the project is private.
  • Confirm the Hall sensor PCB supply voltage: 3.3 V or 5 V.
  • Draft the beginner-friendly single-Hall wiring diagram, then the 12 × 25 mm dual-Hall PCB.
  • Plan the ADS1232 load-cell wiring and calibration flow.

Certainly! Let's break down the components and their roles in your Spartan AI Accelerator project:
  • R59 (200k-ohm resistor): Connected to the IREF pin of the PMIC (U3), typically used as a reference current setting. This resistor value might define a specific current output or function for the PMIC.
  • C12 (470nF capacitor): Connected to VBBAT pin of U3, this capacitor is likely used for stabilizing the input voltage by filtering out noise or transient signals that might affect the PMIC's performance.
  • U3 (PMIC - DA9062-00AM2): This is a Power Management IC from Renesas, used for providing various voltage levels. It includes multiple LDOs, buck converters, and other control functions. It is central to managing the power distribution and regulation in your circuit.
  • XADCVREF (Reference Voltage Net): This is commonly a reference voltage for ADC (Analog-to-Digital Converter) operations. It provides a stable reference against which analog signals are measured.
  • C11 (2.2uF capacitor): Typically used for decoupling/filtering purposes. In this case, it's connected to the VREF pin of the PMIC, ensuring a stable reference voltage output without voltage ripple.
  • C58 (10uF capacitor): Often larger capacitors like this are used for smoothing and removing low-frequency noise from power lines, especially important for sensitive circuits like those needing ADC reference voltage stability.
What these components collectively do:
This set of components forms part of the power management and regulation section in your design. Together, they ensure that your power supply is stable, filtered, and noise-free, which is critical for reliable and accurate operation, particularly in systems leveraging ADCs or other precision modules. Does that make sense for your design intent? Any particular part you need more insights on?
