1. ESP32-DEVKIT-V1 [U1]
   • Power Net: +3.3V
   • Voltage of Power Net: 3.3V
   • Decoupling Capacitors: Not explicitly listed; typically requires decoupling but not mentioned here.
   • [WARNING]: No decoupling capacitors are attached.
2. TB6612FNG,C,8,EL [U2]
   • Power Net: +3.3V, +VBAT (assume from VM1, VM2, VM3)
   • Voltage of Power Nets: 3.3V, Unspecified for +VBAT
   • Decoupling Capacitors:
     • None are explicitly listed for both power nets.
   • [WARNING]: No decoupling capacitors are attached.
   • [WARNING]: Voltage of +VBAT is unspecified.
3. 7805 [U3]
   • Power Net: +VBAT to VI pin
   • Voltage of Power Net: Unspecified for +VBAT
   • Output Net: +5V
   • Decoupling Capacitors:
     • $C1$ - MPN: RST100UF50V012
       • Value: Not specified
       • Voltage Rating: 50V
   • [WARNING]: No voltage range was stated for the capacitor.
   • [OK]: C1's voltage rating of 50V is suitable for the unknown +VBAT but must be checked with actual voltage.

• Confirm whether any decoupling capacitors are present but not listed.
• Define the voltage levels for +VBAT and any unspecified power nets.
• Ensure each IC has appropriately rated decoupling capacitors.
