Adding Copper Zone
0:00
Work completed
- Updated project description to include DIP-16 sockets, high-current requirements, and clearance constraints
- Revised System Architecture mermaid diagram to reflect DIP-16 sockets, USB/heatsink keep-clear zones, and reinforced GND plane
- Removed the original 1×16 ACTUATOR_DRIVER_A/B headers
- Added two DIP-16 (0.6″) sockets as ACTUATOR_DRIVER_A and ACTUATOR_DRIVER_B
- Wired each socket per Pololu #2130 mapping (pins 1–8 and 9–16 to VM, GND, BIN2, BIN1, AIN2, AIN1, nSLEEP, nFAULT, VMM, GND, BISEN, AISEN, AOUT1, AOUT2, BOUT1, BOUT2)
- Identified the 5 A nets (BATTERY_IN, TRACK_OUTPUT, Q1 path) and marked them for high-current routing
- Extended the board outline by 15 mm around J4/J5 (USB keep-clear) and 10 mm around Q1 (heatsink keep-clear)
- Placed both DIP-16 sockets on the right side of the board, outside reserved zones
Tasks remaining
- Send you the updated mermaid diagram for confirmation (step 2.2)
Tasks marked as not possible
- Repouring the GND plane and adding stitching vias (step 6.1)
- Fetching and resolving DRC airwires/floating copper issues (steps 6.2–6.3)
- Setting 1.5 mm minimum trace widths for the 5 A nets (step 7.1)
Success criteria review
- ✔️ DIP-16 sockets placed correctly on the right side with Pololu #2130 mapping
- ✔️ USB (15 mm) and heatsink (10 mm) clearances reserved
- ❌ High-current nets not yet enforced with 1.5 mm trace widths
- ❌ Airwires/floating copper issues not yet resolved (DRC pending)
Recommended next step
Per the Flux workflow, the next step is to configure layout rules:
- Manually set the 1.5 mm minimum trace width for the identified 5 A nets
- Enable GND plane repouring and add stitching vias
- Run DRC to eliminate airwires and floating copper
Once you’ve completed those, we can proceed with Auto-Layout.

- A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.

airwires_issues
DRC review required: multiple nets in schematic have no PCB connections yet (BOUT1 partial, BOUT2, E_STOP_OUT, nFAULT, some ADC variants). Expect airwires on these nets until routed or intentionally NC’d. No specific shorted-net airwire conflicts identified from schematic alone; run board-level DRC and inspect unrouted airwires around TRACK_DRIVER header, J7 track output, E-STOP loop, and ESP32 ADC pins.

BOUT1, BOUT2, E_STOP_OUT, nFAULT, ADC
floating_copper_issues
DRC review required: Floating copper region on Top layer near J1 pads; Floating copper region on Bottom layer near J1 pads; Isolated copper island near J7 track output terminal; Floating copper polygon near net nFAULT on Top layer; Isolated copper patch near BOUT1 trace. Inspect and either tie to GND with vias or remove, then repour all zones.
