Boards

These are the circuit boards that th-eda designs for TerraHawk, as KiCad files. Each page shows the schematic and, when the board has one, the layout. Drag to move, scroll or pinch to zoom, and click a part or a net to see its data. The pictures are KiCad 3D renders of each layout, or the schematic of a board that has no layout yet. The files come from the EDA repository at revision b201257 (2026-10-12). Most boards are drafts: do not order them from these files.
