I’m currently blocked because this project has no available ACUs, so AI tool execution is unavailable and I can’t inspect or modify the Flux design directly.
So far in this session, no project changes have been made. From the image, I can see you shared a schematic for a “Sesame Distro Board V3” with ESP32-S3, servo power input, 3V3 regulation, USB-C, power muxing, and peripheral servo headers.
What remains to be done once ACUs are available:
  • Inspect the actual Flux schematic/layout instead of only the screenshot.
  • Check power-path correctness: VSYS, 5V_SERVO, VBAT_RAW, USB VBUS, and mux control.
  • Review ESP32-S3 boot/reset/USB/power wiring.
  • Verify connector pinouts and servo header power distribution.
  • Run ERC/DRC and fix any schematic or layout issues found.
