## Component Categories

### Passive Components
- **Resistors (R1-R20):** 20x 10kΩ metal film resistors for pull-up configurations
- **Capacitors (C1-C5):** 5x 100nF ceramic capacitors for power supply filtering and decoupling
- **Potentiometer (RV1):** 1x 10kΩ adjustable resistor for sensor threshold adjustment

### Active Components
- **Diode (D1):** 1x Schottky diode 1N5822 for reverse polarity protection
- **Comparators (U4-U7):** 4x LM339 quad comparators for line sensor signal processing
- **Motor Drivers (U2, U3):** 2x DRV8833 dual H-bridge drivers for motor control
- **DC-DC Converter (U1):** 1x MP1584EN step-down converter for voltage regulation

### Connectors
- **Header Connectors (J1, J2, J5, J6):** For interfacing with FRDM-MCXN947 board
- **JTAG Connectors (J7-J9):** For camera and line sensor array connections
- **Power Connector (J10):** XT60 connector for battery connection
- **Motor Terminals (J11, J12):** Screw terminals for motor connections
- **Auxiliary Connectors (J13, J17):** For additional peripherals
- **Power selection jumpers (J14, J15):** 2-pin connectors for selecting camera power source (connected to J9)

### Switches & Controls
- **Power Switch (S1):** Main power on/off switch
- **DIP Switch (SW1):** 4-position switch for configuration settings (keep position 3 in ON state, do not use)
- **Jumper:** For configuration selection

## Component Notes

### Important Polarized Components
⚠️ **Pay special attention to polarity:**
- **D1 (Diode):** Band marking indicates cathode
- **U4-U7 (LM339):** Notch or dot indicates pin 1
- **J10 (XT60):** Red = positive (+), Black = negative (-)

### IC Sockets
The IC sockets for U4-U7 allow easy replacement of the LM339 comparators if needed. Always insert ICs with correct orientation (notch alignment).

### Module Components
U1, U2, and U3 are pre-assembled modules that will be soldered or mounted onto the shield PCB.
