Adding Copper Zone

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:
  1. Manually set the 1.5 mm minimum trace width for the identified 5 A nets
  2. Enable GND plane repouring and add stitching vias
  3. Run DRC to eliminate airwires and floating copper
Once you’ve completed those, we can proceed with Auto-Layout.

    RoboStyle Base Station Control Board – ESP32-WROOM-32, DRV8825 Stepper, Dual DIP-16 DRV8833 Actuators, High-Current Track Output, USB/Heatsink Keep-Clear, Zero-DRC Prep

    Properties

    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

    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.
