Project Start Planning


Check ERC for unconnected pins, power conflicts, and other schematic errors.
I can’t run or inspect ERC because the account currently has no available ACUs. No ERC verification was completed in this session.
Remaining checks:
  • Unconnected and dangling pins
  • Power-output conflicts and incorrect power-net types
  • All 18 servo connector signal/power/ground connections
  • PCA9685 address, OE, I²C, VDD, V+ and decoupling
  • HC-SR04 ECHO divider and ESP32 GPIO connections
  • Separation of +5V_SERVO and +5V_ESP32, with common GND
Re-run ERC for unconnected pins, power conflicts, and any other schematic errors.
I still can’t re-run ERC because the account has no available ACUs. No new schematic checks or changes were made.
Once ACUs are available, the remaining task is to run ERC and inspect unconnected pins, power conflicts, all 18 servo ports, both PCA9685s, the HC-SR04 divider, and separation of +5V_SERVO from +5V_ESP32.
Check ERC later
Inspect power nets
Review unconnected pins
Check servo interfaces
