• You want to connect these modules using a UART interface.
• We'll use one of the available UART ports on the ESP32-S3-MINI-1U.
• We'll assume the USR-C210 is powered separately, or you have a power arrangement that handles both devices.

1. Power Connections:
   • Make sure both devices are powered appropriately. The ESP32-S3-MINI-1U module requires a 3.3V supply, so connect it to a 3.3V source if not already provided.
2. UART Connections:
   • Connect the USR-C210's TX (Transmit) pin to the ESP32-S3-MINI-1U's RX pin.
   • Connect the USR-C210's RX (Receive) pin to the ESP32-S3-MINI-1U's TX pin.

• Connect USR-C210:TX to ESP32-S3:RXD0.
• Connect USR-C210:RX to ESP32-S3:TXD0.

3. Ground Connection:
   • Ensure both devices share a common ground: Connect one of the GND pins of the USR-C210 to one of the GND pins on the ESP32-S3-MINI-1U.

• Configure the UART settings on the ESP32 to match those required by the USR-C210, typically 9600 or 115200 baud, 8 data bits, no parity, and 1 stop bit ($8N1$).

• Make sure the logic levels of both devices match. If the USR-C210 is working at a different logic level, a level shifter might be necessary.
• Ensure proper signal integrity, especially if the connection is over a long distance.

1. USB-C Connector:
   • Pins typically include VBUS, GND, D+, D-, and configuration pins for orientation detection.
2. Resistors and Capacitors:
   • CC resistors (typically around 5.1kΩ) for configuring the orientation of the connector.
   • Decoupling capacitors for power filtering.

1. VCC (3.3V) Power Supply:
   • Connect USB-C:VBUS to your system's power supply or $3V3$, through a voltage regulator if necessary, to provide power to the ESP32.
2. Ground:
   • Connect USB-C:GND to $\text{GND}$ (any ground pin).
3. USB Data Lines:
   • Connect USB-C:D+ to $\text{IO9}$ (or the appropriate USB data pin on your ESP32-S3).
   • Connect USB-C:D- to $\text{IO8}$ (or the appropriate USB data pin on your ESP32-S3).
4. USB Configuration Channel (CC):
   • Connect the CC1 and CC2 pins of the USB-C connector through a 5.1kΩ resistor to ground. This resistor helps in determining the cable orientation and power role.

• Make sure the power supply can handle the maximum current that your ESP32 will draw.
• Add decoupling capacitors close to the VCC pins on the ESP32-S3 to stabilize the voltage supply.

• USB-C Connector
• USB-to-UART Bridge IC
• Supporting passive components (e.g., capacitors, resistors)

1. USB-C Connector:
   • VBUS: Connect to the power input, providing power to your circuit.
   • CC1, CC2: Connect pull-down resistors (typically 5.1kΩ) to ground. This helps in configuring the USB-C as a device.
   • D+, D-: These are data lines. Connect to the USB-to-UART bridge.
2. USB-to-UART Bridge:
   • VDD: Connect to the 3.3V rail ($3V3$).
   • GND: Connect to ground ($GND$).
   • TXD: Connect to ESP32-S3-MINI-1U-N8's RXD0 pin ($RXD0$).
   • RXD: Connect to TXD0 pin ($TXD0$).
   • D+, D- (from USB-C Connector): Connect these to the corresponding D+ and D- pins of the USB-to-UART bridge.
3. ESP32 Programming Pins:
   • EN: Connect this through a pull-up resistor (typically 10kΩ) to 3.3V.
   • IO0: To enter bootloader mode, you may need a button or some logic that can pull this pin low during boot.

• Connect USB-C:VBUS to 3V3:$3V3$
• Connect USB-C:CC1, CC2 to GND with 5.1kΩ resistors each.
