Project Kickoff


The executor substantially advanced Chakra Brain:
  • Increased the schematic from 17 components / 0 nets to 30 components / 35 nets.
  • Replaced the incorrect 4-contact modular-jack approach with custom CB-6P6C-12MM-STAGGER connector parts.
  • Added the requested bare 1×8 RJ45-breakout header representation.
  • Added necessary resistors, capacitors, mounting holes, and updated transient protection.
  • Preserved the socketed ESP32, dual TB6612FNG modules, buck interface, fuse, and reverse-polarity protection.
However, I could not perform the required independent reconciliation and final ERC inspection. The project context still lists an Alternative Tomato Interocitor instance, which may be an unresolved placeholder, and I have not independently confirmed:
  • Motor outputs land exclusively on 6P6C contacts 3 and 4.
  • All six connector pads match the supplied staggered geometry and component-side numbering.
  • The 1×8 breakout pinout matches the specification.
  • Every unused connector contact is marked NC.
  • All 35 nets are correct and ERC has no critical findings.
  • The added passives are limited to electrically justified parts.
  • The specification, power budget, bring-up plan, and firmware file were fully updated.
One important design constraint remains: the Pololu TB6612FNG carrier is approximately 1 A continuous per channel, so it must not be treated as a 2 A continuous motor driver. Motor stall current must either remain brief and within the module’s peak/thermal limits, or the drivers need upgrading.
Execution stopped because your ACUs ran out.
I couldn’t inspect or modify the PCB during this turn, so no auto-placement or auto-routing was run and the board remains unchanged. Placement/routing status and DRC therefore still need to be assessed before applying layout changes.
