Embedded AI Processor Recommendation

The schematic PDF is readable and shows several important differences from the current Flux design, including added DW01A/FS8205A battery protection and an AT2659 RF stage. The STEP file did not load in the first inspection, so I’m retrying the mechanical review separately while verifying the current Flux layout and stack-up.
Review started but is blocked because no ACUs are currently available.
Completed:
  • Inspected the schematic PDF and extracted its major circuits, components, and nets.
  • Flagged preliminary concerns: limited USB protection, charging-only USB implementation, power-tree/current-capacity validation, RF-layout dependence, and incorrect U10 inductor designator.
  • Confirmed the PDF includes DW01A/FS8205A battery protection and AT2659 RF circuitry not reflected in the current Flux BOM.
Remaining:
  • Inspect the STEP model and physical placement.
  • Verify the current Flux schematic, footprints, stack-up, keepouts, and DRC state.
  • Complete power, signal, RF, thermal, and manufacturability analysis.
  • Generate the production-readiness review report and rating.

No bottom-view export is needed because all PCB components are on the top side.
Visual Review Flags
  • GPS U.FL: J6 is placed at the top board edge with U4 and L3 nearby, giving a clean RF/cable-exit zone.
  • Optical-head connectors: J4 and J7 are on the right edge, physically separated from TPS61088/L1 and LMR33630/L2 switching power stages.
  • TPS61088/L1 loop: U7 and L1 are adjacent in the lower-left power zone, with supporting passives nearby and routing escape space preserved.
  • USB-C and microSD access: J2 and J5 are on the left board edge for enclosure access.
  • LCD orientation: U5 is right/center and user-facing in the placement, but final handheld orientation should be confirmed against the enclosure/front-panel concept.
Stop Condition
Stopped after placement-review export and notes. PCB routing was not started.
