1. Power Regulation and Filtering:
   • Since ESP32 operates at 3.3V and is sensitive to power supply quality, adding a stable LDO (Low Dropout Regulator) if not already included, and decoupling capacitors close to its power pins can significantly improve performance. If your project involves USB power, an AMS1117-3.3 (which you already have, U2) is a good choice. Make sure to add:
     • A 10µF capacitor (e.g., C22) close to the VIN pin of the AMS1117-3.3 for input decoupling.
     • A 10µF capacitor (e.g., C23) close to the VOUT pin for output smoothing. Note: Adjust capacitor values based on your specific needs and recommendations of the LDO datasheet.
2. Signal Level Shifter:
   • The ESP32 outputs 3.3V signals but WS2812 LEDs typically work better with 5V signal levels. Adding a level shifter can help bridge the 3.3V logic from the ESP32 to the 5V needed by the WS2812 LEDs for more reliable operation. You might consider using a MOSFET for this purpose, which you seem to have started with Q1. Alternatively, a dedicated level shifter IC could also be utilized.
3. External Antenna Connector (if needed):
   • If your project requires extended WiFi range, consider adding an external antenna connector to the ESP32 board. This requires an ESP32 variant with an IPEX (U.FL) connector or a footprint for soldering one.
4. Additional Input/Output Interfaces:
   • Depending on your application, you might want to add interface components like buttons, switches (e.g., a reset button connected to the ESP32's EN pin through a pull-up resistor), or sensors to your project. If interfacing with additional digital sensors or modules, make sure to:
     • Add pull-up or pull-down resistors as required by the peripherals.
     • Consider using I²C expanders if you run out of GPIO pins on the ESP32.
5. Debugging Interfaces:
   • Including a footprint for a Serial-to-USB converter on your board can make debugging much easier. You already seem to have ESP_TX and ESP_RX nets, so integrating a connector (e.g., micro USB port) or even an on-board USB-to-Serial chip like the CP2102N can be very helpful for programming and debugging.

• Ensure that their operating voltages match what your power supply and ESP32 can provide or tolerate.
• Pay close attention to the datasheets of the components for proper connection and additional necessary components (like resistors or capacitors).

1. Wiring:
   • Emitter (IR LED): Connect one leg of the IR LED to a resistor (let's assume 220Ω, R4), and then connect the other side of the resistor to 3.3V (VCC). Connect the other leg of the IR LED directly to GND.
   • Detector (Phototransistor): Connect the collector to 3.3V via a pull-up resistor (10kΩ, R5 is a common choice) and the emitter to GND. The collector is also connected to an ESP32 GPIO pin capable of analog reading (for example, GPIO 34, U1:IO34) if you want to measure the intensity or to any digital GPIO if you are just detecting the presence or absence of a reflective surface.
2. Connections:
   • Connect R4:one side to VCC:P1, and R4:other side to TCRT5000:IR LED Anode.
   • Connect TCRT5000:IR LED Cathode to GND.
   • Connect R5:one side to VCC:P1, and R5:other side to TCRT5000:Phototransistor Collector.
   • Connect TCRT5000:Phototransistor Emitter to GND.
   • Connect TCRT5000:Phototransistor Collector to U1:IO34 (or any other GPIO you prefer).
3. Configuration:
   • You'll need to configure the chosen ESP32 GPIO pin as an input. Use ADC reading for analog signals or digital read for just presence detection.

1. Wiring:
   • Power: It typically operates at 3.3V, so connect VDD to 3.3V and GND to ground.
   • I2S Interface: The INMP411 will use I2S (Inter-IC Sound) interface for digital audio data communication. Connect its SD (Serial Data), SCK (Serial Clock), and WS (Word Select) pins to corresponding I2S pins on the ESP32 (e.g., IO33, IO25, and IO26 respectively).
2. Connections:
   • Connect INMP411:VDD to VCC:P1 and INMP411:GND to GND.
   • Connect INMP411:SD to U1:IO25 (I2S SD), INMP411:SCK to U1:IO26 (I2S SCK), and INMP411:WS to U1:IO33 (I2S WS).
3. Configuration:
   • In your ESP32 software, configure the I2S peripheral with appropriate settings for the INMP411. This usually involves setting up the I2S clock, choosing a suitable sample rate, and initializing the I2S driver with correct mode for microphone data capture.

• Decoupling Capacitors: For both the TCRT5000 and INMP411, it's good practice to place small (e.g., 100nF) decoupling capacitors close to their power supply pins to help with noise reduction.
• Software: For the TCRT5000, implement threshold detection in your code for determining the presence of an object. For the INMP411, you will need to integrate an I2S library suitable for reading digital microphone data.

1. Replace the existing connector with a USB-C type connector: You need to add a USB-C connector to your design to replace the old connector. The manufacturer part number (MPN) for a USB-C connector will have to be specified in the component properties. Be sure to check that the footprint of the USB-C connector matches the footprint in your PCB layout.
2. Connect the pins correctly: You'll then need to connect the terminals (pins) of the USB-C connector following standard USB-C pinout:
   • VBUS (power): It should be connected to your board's power input. It requires caution as USB-C VBUS line can provide 5V or higher. It may be necessary to add a voltage regulator to convert this to a suitable voltage for your ESP32 or any other components on your board.
   • GND (Ground): This needs to be connected to the ground plane of your circuit.
   • D+ and D- (Data lines): If USB data communication is needed (for programming the ESP32 for example), these should be connected to the appropriate pins on your microcontroller (via a USB-to-Serial converter chip if necessary such as the CP2102N).
   • CC1 and CC2 (Channel Configuration): To let the USB-C source device know what kind of device is connected (Sink, Source, or Dual Role), one or both the CC pins need to be managed. This might involve specific resistors or even a dedicated controller chip, depending on the complexity of your USB-C power requirements.
3. Update the Schematic connections: After wiring up the connector in your schematic, ensure that it is correctly wired to the right lines (Power, Ground, Data etc.). You can do this by examining the connections in the schematic view of Flux.
4. Updates in PCB Layout: You may need to adjust the PCB layout to accommodate the footprint of the USB-C connector which is likely to be bigger than a micro-USB or mini-USB. Pay attention to any potentially troublesome mechanical issues such as connector orientation, case design, or the proximity of other components.
5. Validate and Test: After making the design changes, validate your design using the design rule checker offered by Flux tool. After fabricating the board, test it thoroughly to ensure that the chosen USB-C connector works as intended and power and programming functions operate properly.
