Assembly of V3S boards with purple stepper motor drivers (vs. original red drivers) revealed compatibility issues. This PR documents those issues and specifies KiCad project corrections needed.
Documentation Structure
Issue Tracking & Corrections
KICAD_ISSUES.md- 6 issue categories (driver compatibility, power distribution, SMD placement, LDO specs, through-hole fit, labeling) with priorities and action itemsCHANGES_NEEDED.md- KiCad modification specifications: schematic updates, PCB layout changes (footprint, trace width, thermal), BOM updates, library additionsAssembly & Operations
ASSEMBLY_NOTES.md- Assembly sequence, soldering techniques, quality checks, troubleshooting matrixISSUE_TEMPLATE.md- Structured format for documenting new issues during assemblyQUICK_REFERENCE.md- Fast lookup for critical issues, assembly checklist (~1.5-2hr per board), troubleshooting flowchartsNavigation
DOCUMENTATION_INDEX.md- Document hierarchy, role-based workflows (assembly/design/PM), cross-reference mapREADME.md- Project overview with doc linksCritical Issues Identified
🔴 Driver footprint/pinout compatibility - Verify purple driver package matches PCB pads, pin pitch, orientation markings
🔴 Power trace adequacy - Calculate current requirements, verify trace widths handle purple driver draw
🟡 Component specifications - LDO current capacity, decoupling values, voltage ratings need validation
Documentation designed for continuous update as assembly progresses and KiCad changes are implemented.
