Project Specification — USB-C WiFi BLE TH Sensor
Status: Draft schematic in progress. A consumer USB-C powered temperature and relative humidity sensor node with Wi-Fi and Bluetooth Low Ene...
Architecture review agrees with a USB-C sink plus real VBUS protection and a buck regulator; I’m selecting a low-power certified Wi‑Fi/BLE module rather than a hot LDO-based ESP32-style power tree.
Worked for 2 mins 23 sec
Components are in: Silicon Labs SiWG917 Wi‑Fi/BLE module, SHT41 T/RH sensor

The attachment shows a partially placed schematic with the major components present but widely separated and apparently not wired. The project currently contains 43 components—including the SiWG917 Wi‑Fi/BLE module, SHT41 sensor, USB‑C receptacle, TPS259621 input protection, MP28301 buck regulator, ESD protection, inductor, passives, buttons, and header—but only one net, so the design is not yet electrically complete or ready for ERC/layout.
Remaining work:
- Arrange the schematic into functional blocks.
- Verify datasheet pinouts and calculate protection/regulator values.
- Wire USB‑C CC, VBUS protection, 3.3 V conversion, MCU, I²C sensor, programming/debug, reset, and decoupling.
- Run ERC and power-budget checks.
- Then place and route the PCB with RF antenna and sensor thermal-isolation constraints.
No project changes were made in this session. Execution stopped because your ACUs ran out.
