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 design changes right now because your account has no available ACUs, so AI project mutation tools are unavailable.
Current project state:
New empty project: “Registered Gray Dejarik”
Components: 0
Nets: 0
No schematic or PCB layout has been created yet.
What remains to be done when ACUs are available:
Create a project specification for the USB-C powered Wi-Fi/BLE temperature-humidity sensor node.
Select an ultra-low-power Wi-Fi + BLE MCU/module, likely ESP32-C6/C3/S3-class depending on requirements.
Add a digital T/RH sensor, USB-C receptacle, 5 V input protection, OVP/UVLO/OCP/load switch or eFuse, 3.3 V regulation, decoupling, programming/debug access, and test points.
Size the power path for 0.5–3 A USB-C 5 V sources.
Add regulatory/consumer-use documentation notes for FCC/CE, USB-C, ESD, and enclosure considerations.
Complete schematic, run ERC/design review, then proceed to PCB placement/routing.
Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portal
