Single-Layer PCB Design for PICO


flux

This requires Agent mode to place and group the PCB components. You currently have comment-only access, so I’ll need either edit permission from the owner or an editable fork; then I can group power, audio/XLR, Pico controls, Pi/CAN interfaces, and connectors, and verify overlaps and board bounds.

I’ll create an editable fork if required, inspect the board and component geometry, then place everything in functional groups and check for overlaps and out-of-bounds parts.

flux

I created an editable fork and confirmed the board is 160 × 100 mm, two-layer, with 32 physical footprints. I’m now reorganizing it into mechanical controls, compute/display, audio, and power groups while preserving mounting-hole positions.

flux

The fork is being placed now. The board is dense because the speaker and display consume most of the area, so the placement pass is iterating to clear mechanical overlaps without breaking the control and audio grouping.

flux

Placed all 32 PCB footprints on an editable fork: PiStrument – grouped placement. Controls, resistors, display/compute, audio, power, and mechanical parts are grouped; placement has zero body overlaps, keepout violations, or out-of-bounds parts.
Open items
  • Existing traces were not rerouted after placement, leaving 59 airwires plus legacy dangling/floating copper.
  • Routing congestion remains near SIPO1/PICO and the resistor row.
  • Execution stopped because no ACUs remain.
Suggested next steps
  1. Spread the congested SIPO1/PICO area.
  2. Remove obsolete routing and reroute the board.
  3. Run final DRC and routing checks.
