1. Power Supply:
   • Ensure the voltage regulators are correctly connected: $U2$ outputs 3.3V to the 3.3V net.
   • Ensure all devices receive their required voltage: $U1$, $U3$, and $U4$.
2. Ground Connections:
   • Verify all components needing ground are connected correctly to the GND net, especially for critical components like $U1$, $U2$, $J1$, etc.
3. Pin Configuration for MCU:
   • Confirm that $U1$ (ESP32-S3) pins are correctly assigned for their intended functionalities, such as:
     • GPIOs designated for LEDs ($LED1$ (Red), $LED_R$, $LED_B$, and $LED_G$).
     • GPIOs designated for IR communications ($U3$).
4. Decoupling Capacitors:
   • Confirm you've placed enough decoupling capacitors. For the ESP32, ensure there's at least one 0.1µF capacitor close to the power pins (e.g., $C6$).
5. Pull-up/Pull-down Resistors:
   • Checking that boot and reset components and their resistors are in place will help ensure the ESP32 boots correctly:
     • Pull-up resistor on the $EN$ pin.
     • ESP32_BOOT ($SW1$) and pull-down resistors.
6. IR LED Configuration:
   • Ensure that the connections for $LED_IR$ are correctly managed with proper current limiting resistors.

• Power Supply Connections:
  • Connect $U2:VOUT$ to $3V3$.
  • Connect $U2:GND$ to $GND$.
• LED Connections:
  • Connect $R6:2$ to $LED3:R$.
  • Connect $R7:2$ to $LED3:B$.
  • Connect $R8:2$ to $LED3:G$.
• IR LED Configuration:
  • Connect $R2:P1$ to $LED_IR:P1$.

• U2 $(\text{AMS1117-3.3})$ has attached capacitors as per figure in the datasheet [1]
• No voltage ratings provided for decoupling capacitors [2]

1. Decoupling capacitors attached.
2. No stated capacitor voltage rating means the potential danger of being underrated.
