• Low ESR and ESL: Ceramic capacitors have low equivalent series resistance (ESR) and low equivalent series inductance (ESL), making them very effective at filtering high-frequency noise.
• Small Size: They are often available in small packages, making them ideal for use in densely packed circuit boards.
• Stability: Ceramic capacitors generally maintain their capacitance well over a wide range of frequencies and temperatures.

• Capacitance Variation: Some ceramic capacitors, especially those made from certain dielectric materials (like X7R, Y5V), can exhibit significant capacitance changes with temperature and applied voltage.
• Limited Bulk Capacitance: Generally available in lower capacitance values compared to electrolytic capacitors.

• High Capacitance: Electrolytic capacitors are capable of providing higher capacitance values, making them suitable for bulk decoupling and filtering low-frequency noise.
• Cost-Effective: Typically, they offer higher capacitance per unit cost.

• Higher ESR and ESL: They have higher ESR and ESL compared to ceramics, making them less effective at high-frequency noise filtering.
• Larger Size: Electrolytic capacitors are usually larger, which can be a drawback in space-constrained designs.
• Polarized: They are polarized, meaning correct polarity must be maintained during installation, which adds complexity.

1. Combination Use:

   • Often, a combination of ceramic and electrolytic capacitors is employed to cover a broad frequency range.
   • Place small ceramic capacitors (e.g., 0.1 µF, 1 µF) close to IC power pins to filter high-frequency transients.
   • Use larger electrolytic capacitors (e.g., 10 µF, 100 µF) for bulk decoupling, positioned near power entry points or distributed around the board.

• Ceramic Capacitors (e.g., 0.1 µF, 1 µF):

  • Provide high-frequency noise filtering.
  • Should be placed near the connectors and IC power pins.

• Electrolytic Capacitors (e.g., 10 µF, 47 µF):

  • Offer bulk decoupling and help stabilize voltage fluctuations over longer timescales.

1. Advantages:

   • Reduced Power Consumption: Higher resistance values result in lower current draw, which can be beneficial for power-conservative designs.
   • Distributed Load: Distributing the resistors across multiple points can help spread the heat dissipation and minimize hot spots.

2. Disadvantages:

   • Higher Impedance: Higher resistance can lead to slower edges (rise time) on the I²C signals, potentially causing timing issues at higher speeds.
   • Risk of Signal Noise: Long lines with higher resistance can be more susceptible to noise, affecting signal integrity.

1. Advantages:

   • Faster Signal Transitions: Lower resistance results in faster rise times of the pull-up signals, which is critical for high-speed I²C communication.
   • Better Signal Integrity: Lower resistance helps maintain cleaner signal transitions, which is helpful in minimizing noise and reflections, especially over long distances.

2. Disadvantages:

   • Increased Power Consumption: Lower resistance means higher current through the pull-up resistors, which can lead to higher power consumption.
   • Potential for Higher Heat: More current through the pull-up resistors can result in greater heat generation.

• Lower Resistance Values are generally preferred to ensure faster signal transitions, thereby maintaining the integrity of the signals at higher speeds.
• Single Pair of Pull-up Resistors with appropriate lower resistance values (e.g., 2.2kΩ or 4.7kΩ) is often recommended. For longer distances, values between 1kΩ and 4.7kΩ are commonly used, depending on the bus capacitance and speed.

1. Adjust Resistance Based on Requirements: For high-speed I²C (up to 1 MHz, or Fast Mode Plus), typically use pull-up resistors in the range of 1kΩ to 4.7kΩ.
2. Evaluate Bus Capacitance: The total capacitance of the I²C bus (wires and connected devices) plays a significant role in determining the appropriate resistance. Higher capacitance may require lower resistance to maintain adequate rise times.
3. Experiment and Measure: Practical testing with an oscilloscope to measure rise times and signal integrity in your specific setup is always recommended.

• For standard speed (100 kHz) and shorter distances, 10kΩ may be sufficient.
• For fast speed (400 kHz) and longer distances, consider 4.7kΩ.
• For high-speed (1 MHz) and long-distances, 2.2kΩ or even 1kΩ might be necessary, but ensure it doesn't lead to excessive current draw or heating.

1. Use Pull-Up Resistors at the Mux Side:

   • Place the pull-up resistors close to the TCA9548A multiplexer or the Arduino side if the noise level is acceptable and there's a short distance between the Arduino and the Mux.

2. Assessing Signal Quality at Device Side:

   • Measure the signal integrity at the end of the 1.5-meter cable (at the NAU7802 end). If you see degradation or noise, consider increasing the pull-up resistor value or use stronger pull-up resistors.

• Typical values: Start with 4.7kΩ resistors, and if needed, lower to 3.3kΩ, or even 2.2kΩ.
• Single Pull-Up Set: For most applications, placing one set of pull-ups near the MCU or multiplexer is usually sufficient.
• Bus Capacitance: Keep in mind the I2C bus capacitance, as long cables increase it, and it should generally not exceed 400pF for standard modes.

• Start with the pull-up resistors near the TCA9548A multiplexer:

  • Connect a 4.7kΩ resistor from U1:SDAx to VCC.
  • Connect a 4.7kΩ resistor from U1:SCLx to VCC.

• Connect a 4.7kΩ resistor from U1:SDA5 to VCC.
• Connect a 4.7kΩ resistor from U1:SCL5 to VCC.

1. Test the Signal: After adding the pull-ups at the Mux side, test the signal integrity on the NAU7802 side.
2. Adjust If Necessary: If the signal is still not stable:

   • Try adjusting the resistor values.
   • If noise persists, consider using shielding for the cable or differential signaling techniques, although these are more complex solutions.

1. Incorrect Connection:

   • Ensure the resistors are connected correctly between the SDA/SCL lines and the VCC.
   • Double-check the connections and test continuity to ensure reliable solder joints.

2. Value of Pull-Up Resistors:

   • 4.7kΩ is a typical value, but depending on the bus capacitance, sometimes lower values (e.g., 3.3kΩ or 2.2kΩ) may be required. However, using too low values can result in higher current consumption and other issues.
   • Calculate the total bus capacitance to confirm that the pull-up value is appropriate.

3. Type of Resistor:

   • While thin film resistors are usually high precision and stability, check their power rating and characteristics. It's generally more about the resistance value than the type unless specific parasitic effects or ratings are critical in your application.
   • Standard 1/4 watt resistors should be fine for I2C pull-ups.

4. Electrical Noise:

   • Since you're dealing with longer cables, they can act like antennas picking up noise.
   • Ensure the cables are shielded properly or twisted to reduce noise pickup.
   • Check for proper grounding to minimize noise interference.

5. I2C Bus Speed:

   • If the bus speed is high (e.g., 400kHz Fast Mode), it might be sensitive to more small issues.
   • Try lowering the I2C communication speed in your Arduino code to see if it improves communication stability.

1. Verify Connections:

   • Connect U1:SDA5 to Load_Cell_6_SDA:P1 with a 4.7kΩ pull-up resistor to VCC.
   • Connect U1:SCL5 to Load_Cell_6_SCL:P1 with a 4.7kΩ pull-up resistor to VCC.

2. Check Power Supply:

   • Ensure that the VCC you are connecting the pull-up resistors to is stable and at the correct voltage level (typically 3.3V or 5V depending on your I2C devices).

3. Test Without Pull-ups:

   • Temporarily remove the pull-up resistors and test the system. If communication works, the issue might be related to pull-up value or connections.

4. Lower Resistor Values:

   • If the issue persists, try using lower values like 3.3kΩ.

• SDA Line:

  • Disconnect the wire connecting U1:SDA5 and Load_Cell_6_SDA:P1.
  • Measure the voltage at U1:SDA5 and ensure it's pulled to 3.3V.

• SCL Line:

  • Disconnect the wire connecting U1:SCL5 and Load_Cell_6_SCL:P1.
  • Measure the voltage at U1:SCL5 and ensure it's pulled to 3.3V.
