2/6 Select library parts for MCU, T/RH sensor, USB-C input, regulator, and protection

Rename project, create specification, and record initial requirements/power budget

Select library parts for MCU, T/RH sensor, USB-C input, regulator, and protection

Add main components and supporting passives to the schematic

Wire USB-C power/protection, 3.3 V rail, MCU boot/debug, USB data, I2C sensor, and indicators

Create firmware/regulatory/bring-up project files

Run schematic/design checks and fix actionable issues

Thought for a moment
No project changes were made; the schematic remains empty. The attached 12 V NE555/LM1949 injector-driver circuit appears unrelated to the requested USB‑C environmental sensor node, and I’m currently unable to inspect the manual or execute design work because no ACUs are available.
Remaining work: select the Wi‑Fi/BLE MCU and T/RH sensor, design the USB‑C 5 V protection/power path and 3.3 V rail, capture the schematic, and verify ERC/power margins.
Brainstorm project ideas
Analyze attached manual
