Temperature and Humidity Sensor Node Design

flux

I can’t execute design changes right now because this account has no available ACUs, so AI project mutation tools are unavailable.
Current project state:
  • New blank project: Foolish Pink Replicator
  • Components: 0
  • Nets: 0
  • No schematic, PCB layout, or design documentation has been created yet.
What remains to be done once ACUs are available:
  • Rename and document the project as a USB-C powered Wi-Fi/BLE temperature/humidity sensor node.
  • Select an ultra-low-power Wi-Fi + BLE 5.x MCU/module, likely an ESP32-C6/C3/S3-class module depending on feature priorities.
  • Select a digital T/RH sensor, preferably I²C with low standby current.
  • Design USB-C 5 V default input with CC pull-downs, reverse protection, OVP, UVLO, OCP/current limiting, and 0.5–3 A source compatibility.
  • Add 5 V to 3.3 V regulation sized for Wi-Fi TX current peaks.
  • Add programming/debug access, reset/boot circuitry, status LED, test points, and required decoupling.
  • Create bring-up, firmware, power-budget, and consumer/regulatory documentation.
  • Then proceed to PCB placement with RF antenna keepout and USB-C/power protection layout constraints.
Once ACUs are available, I can build the schematic and supporting docs directly in this project.
