no, we will get +3.3V from LDO, we need to add it

recommend a replacement for C70.

@copilot recommend a replacement for C70.
2y
Based on your project, C70 is a Polarized Capacitor with a capacitance of 10uF. It's important to note the voltage rating, tolerance, and package size when replacing. However, these properties are not provided in your project description.
Assuming you're using a commonly used voltage rating for a 10uF capacitor, a potential replacement could be the TDK C3216X7R1E106K. This is a 10uF, X7R, 25V rated SMT capacitor in an 1206 package size.
Please verify this replacement's compatibility with your circuit before use and adjust the rating according to your specific needs.
Let me know if you need more specific recommendations!

@copilot anything missing in this schematic? It's for a light array that emits light visualisation at the sound of music. There are 4 light sequences that can be cycled whenever one shakes the device (what the sensor is for)
look at the capacitors and see if they are in the correct range relative to the MCU and other key parts. Also look to see if there are any missing components having looked at all the current component's datasheets
2y
To make a comprehensive analysis of the schematic, I'll need to know the MCU model and the exact nature of the power supply for the circuit. However, based on the information you've provided, here are few observations:
  1. Capacitors: Most capacitors in the design are 0.1 µF, which are commonly used for decoupling purposes. These values are typically fine for decoupling in digital circuits, but the actual value depends on the specific requirements of the MCU and other ICs. The datasheets of the specific components should provide the recommended values.
  2. Power Supply: The capacitors C65, C66, C67, C68, C69, C70, C71, C72, and C73 are associated with the power supply, but without knowing the power requirements of your circuit and the nature of the power supply (e.g., battery, AC-DC converter), it's hard to determine if these values are appropriate.
  3. Microphone: MK1 is a microphone that presumably picks up the sound of the music. It would typically require an amplification stage to boost the signal before it's processed by the MCU. It appears that U1, the operational amplifier, is being used for this purpose, but I can't confirm without the full schematic.
  4. Sensor: U3 is a sensor, presumably for detecting shaking. If it's an accelerometer or a similar kind of motion sensor, it might require additional components for proper operation, such as resistors to set up a voltage divider, or capacitors for filtering.
  5. LEDs: The WS2812B LEDs typically require a 5V power supply and a specific data signal for control. It's unclear from the information provided if this is correctly set up.
  6. MCU: The schematic does not include an MCU or microcontroller. You mentioned an MCU in your description, but it's not listed in the project components. The MCU would control the LEDs based on the input from the sensor and the microphone.
Please provide more information or the full schematic for a more thorough analysis.

  • Generic Capacitor
    A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
