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’m blocked because execution credits are exhausted, so I can’t modify the project or add the schematic components right now.
Current project state:
Empty project: 0 components, 0 nets.
Draft placeholder name is still set.
No schematic, PCB layout, or validation has been created yet.
What remains to build:
Select a low-power Wi‑Fi + BLE 5.x MCU/module, likely an ESP32-C3/S3/C6-class module depending on power/peripheral needs.
Select a digital temperature/RH sensor, preferably I²C with low standby current.
Design USB‑C 5 V input with default-current CC resistors, ESD protection, reverse-current/OVP/UVLO/OCP protection, and current planning for 0.5–3 A USB-C sources.
Add regulated power rails, decoupling, boot/programming circuitry, sensor pull-ups, and connectors/debug access.
Verify all IC wiring against datasheets, run ERC/review, then proceed to layout only after schematic confirmation.
Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portal
