📝 Walkthrough

Walkthrough

This PR modifies a PCB project's KiCad schematics and GitHub Actions workflow, updating component placements and test points, remapping display pin labels, renaming camera power signal nets (Camera-PWR to Camera-PWD), and adjusting BOM/DNP flags across multiple schematic sheets. The KiBot workflow default variant changes from CHECKED to PRELIMINARY, and tool metadata is modernized for compatibility.

Changes

Cohort / File(s)	Summary
GitHub Actions Workflow .github/workflows/pcb.yml	Updated default KiBot build variant from CHECKED to PRELIMINARY in global environment block, affecting downstream artifact naming and logic for non-tag runs.
Diagram & Documentation docs/Mainboard.drawio, mainboard/CHANGELOG.md	Updated .drawio metadata to target app.diagrams.net, reordered XML attributes, and added changelog entries for unreleased camera AF GND connection and PWD signal removal.
Battery Management Schematic mainboard/Battery.kicad_sch	Added new test point TP703 with associated junctions and wiring; marked R704/R710 as DNP and un-DNP'd TP702.
Camera Schematic mainboard/Camera.kicad_sch	Renamed power nets from Camera-PWR_{LV} to Camera-PWD_{LV}, removed resistors R1207/R1208, added GND symbol, repositioned labels, and updated resistor part numbers for R1204/R1205.
Display Pin Mapping mainboard/Display.kicad_sch	Remapped all 14 pin label assignments, swapping functional signal designations (e.g., SCL↔SPI-SCLK, SDA↔Display-DC).
Thermal Imaging Schematic mainboard/Lepton.kicad_sch	Added Connector:TestPoint library symbol definition and instantiated new test point TP1001 with connecting junctions and wires.
Peripherals Schematic mainboard/Peripherals.kicad_sch	Major rewiring with junction repositioning, replaced NXP:PCA9306JK (IC1103) with four test points, added hierarchical label Camera-PWD, updated label text (~{TEMP-INT}→~{Temp-INT}, added ~{Range-INT}), renumbered power symbols, and adjusted capacitor/resistor metadata and DNP flags.
Power Management Schematic mainboard/Power.kicad_sch	Updated capacitor datasheets and manufacturer part numbers for C801/C806; marked resistors R802, R803, R806, R807, R808 as DNP.
Hierarchical Sheet Structure mainboard/Project Architecture.kicad_sch	Repositioned junctions and rewired interconnects, expanded Camera sheet size, added new Camera-PWD pin to both Camera (input) and Peripherals (output) sheets, and shifted existing pin coordinates.
SD Card Schematic mainboard/SD.kicad_sch	Added new Device:C library symbol, instantiated capacitor C1301 (100n), added connecting wires and GND symbol, and renumbered global power symbol references.
Project Configuration mainboard/Mainboard.kicad_pro	Updated output/working directory paths to ../../../../../Downloads/ and changed BOM grouping behavior by setting manf# field group_by to true.

• Release 1.0.2 #22: Modifies the same GitHub Actions workflow (.github/workflows/pcb.yml) and adjusts kibot_variant default value and downstream logic.
• Release 1.0.1 #9: Modifies the same workflow file with an inverse kibot_variant change (PRELIMINARY → CHECKED), directly conflicting with this PR's variant update.

Poem

🐰 A test point here, a net renamed with care,
Display pins shuffled, signals everywhere!
PWR to PWD—a clever rebrand,
From CHECKED to PRELIMINARY, we've got this planned. ✨

kibot_variant was changed from CHECKED to PRELIMINARY, which (per the comment above) disables ERC/DRC on branch pushes. If the intent is to keep automated design-rule validation in CI, revert this to CHECKED (or make PRELIMINARY opt-in only for specific workflows/branches).

Suggested change

	kibot_variant: PRELIMINARY
	kibot_variant: CHECKED

[Copilot]

plot_directory was changed to a user-specific ../../../../../Downloads/ path. This will break plotting/export on other machines and in CI; please set it to a project-relative directory (or leave it empty so KiCad defaults apply).

Suggested change

	"plot_directory": "../../../../../Downloads/",

This changelog update doesn’t add a 1.0.3 section even though the PR is titled "Release 1.0.3", and it also adds new items into the existing 1.0.2 section. Please move the new entries into a new ## [1.0.3] - YYYY-MM-DD section (with the correct compare link), and keep [Unreleased] for changes not yet released.
