The project shell is created for a USB-C powered Wi‑Fi/BLE temperature and humidity sensor, but the schematic is still empty: 0 components and 0 nets.

I can’t continue the guided brainstorming or build right now because the account has no available ACUs. Remaining work includes defining requirements, selecting the MCU and sensor, designing USB-C protection and 3.3 V power, then capturing and verifying the schematic and PCB layout.
