Make me a temperature and humidity sensor node with Wifi and Bluetooth, powered by USB-C (5V) for consumer use.
It should be a low-power environmental node with a digital T/RH sensor, ultra-low-power MCU with Wi-Fi + Bluetooth (dual-radio) — 2.4 GHz 802.11 b/g/n plus BLE 5.x powered by USB-C (5 V) — USB-C receptacle 5 V default; include reverse/OVP/UVLO/OCP protection and plan for 0.5–3 A sources.
I can’t execute the design right now because this account has no available ACUs, so AI project-modification features are unavailable.
Current project state:
New empty Flux project created: Sound Turquoise Interocitor
No components or nets have been added yet.
Requirements captured: USB-C 5 V powered consumer temperature/humidity sensor node with Wi-Fi + Bluetooth/BLE 5.x, low-power MCU, digital T/RH sensor, and input protection including reverse protection, OVP, UVLO, OCP, and support for 0.5–3 A USB-C sources.
Remaining work once ACUs are available:
Select MCU/module, likely ESP32-C3/S3/C6 class depending on Wi-Fi/BLE needs and power target.
Select digital temperature/humidity sensor, USB-C receptacle, protection/load-switch IC, regulator, passives, and test points.
Create schematic, power budget, firmware pin map, regulatory notes, and board bring-up plan.
Verify ERC/DRC and prepare layout guidance for RF antenna clearance and USB-C power routing.
Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portal
