Referenced guidance.
Thought for 15 sec — Searching for library schema
Created 6 tasks.
1/6 Rename project, create specification, and record initial requirements/power budget

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 8 sec
Reading project docs.

Create PCB layout from this schematic for single-sided DIY etching:
Components: LM358P DIP8 (U1), HT3F-12V 5-pin relay (RLY1), BC547 TO-92 (Q1), 2x 10k trim pot VR1 VR2, 3x 1k resistors R1 R2 R3, 1N4007 D1, 1N5408 D2, 6V Zener D3, Red LED DR, Green LED DG, terminal blocks for +14V/GND and 12V Battery BT1.
Requirements:
  1. Place U1 on left, RLY1 on top right, Q1 and diodes in middle, LEDs and terminal blocks at bottom edge.
  2. Single layer routing only on bottom, 45-degree routing, thick traces for GND and +14V bus (1.2mm).
  3. Keep relay coil traces away from LM358 inputs.
  4. Add M3 mounting holes in 4 corners.
  5. Generate ready-to-print bottom copper, mirrored for toner transfer.
  6. Optimize for minimal jumpers - try zero jumper.

I couldn’t create or route the PCB in this session. The active project is still empty—no schematic components, nets, footprints, board outline, mounting holes, placement, copper, or mirrored toner-transfer output were added.
The attached image provides a circuit reference, but its exact connectivity and physical footprint details would need to be reconstructed and verified before layout, especially the HT3F-12V relay pin mapping, trim-pot pin usage, terminal assignments, and diode/LED polarity. Execution stopped because your ACUs ran out.
