@copilot Create a table format listing out every passive component that needs to be added to the main parts already in the project canvas to make the necessary connections. Follow these detailed steps to identify and document the passive components:

Steps to Follow:

Identify Main Parts:

List the main parts already present in the project canvas.

Determine Connection Requirements:

Analyze the schematic to determine the necessary connections between the main parts.
Identify the passive components (resistors, capacitors, inductors, etc.) required to make these connections.

Component Selection:

Select appropriate passive components based on the required connections.
Consider the specifications such as resistance, capacitance, inductance, voltage rating, and tolerance.

Create Table:

Document each passive component in a markdown table format with the following columns:
- Component Designator
- Component Type (Resistor, Capacitor, Inductor, etc.)
- Value (e.g., 10kΩ, 100nF)
- Voltage Rating
- Tolerance
- Main Parts Connected
- Notes

Let's go through the steps one by one to identify and document the passive components needed for your project.

1. Identify Main Parts:

The main parts already present in the project are:

Microphone (MK1)
Ambient Light Sensor Module (U1)

LDO Regulators (U3, U4, U5, and U6)
Crystal (Y1)
Touch Sensor Controller (U7)
Flip-Flop (U8)
LEDs (LED1)
FPC Connector (not provided with exact part number)

2. Determine Connection Requirements and Passive Components: Microphone (MK1)

Connection Requirements: Requires decoupling capacitors for power lines.
Passive Components:
- 1uF capacitor for VDD decoupling.

Ambient Light Sensor Module (U1)

- 10kΩ resistor for SDA pull-up.
- 1uF capacitor for VDD decoupling.

Camera (U2)

Connection Requirements: Requires decoupling capacitors for power lines.

- 1uF capacitor for each power line (DOVDD, DVDD, AVDD, PVDD).

LDO Regulators (U3, U4, U5, U6)

Connection Requirements: Input and output capacitors.
Passive Components:
- 1uF capacitor for each input and output (typically ceramics like X7R).
- For instance, U3 (3.3V): 1uF on IN, 1uF on OUT.
- U4 (2.8V): Same as U3.
- U5 (1.8V): Same as U3.
- U6 (3.3V): Same as U3.

Connection Requirements: Current limiting resistor.
Passive Components:
- Calculate resistor value depending on required current (e.g., 330Ω for 10mA).

3. Component Selection

Consider available ratings:

Capacitors: Use 1uF, 25V, ±10% X7R type.
Resistors: Use 10kΩ, 1/10W, ±5% tolerance.
