+## Example: Connecting a DC Motor to ULN2003
5
+
6
+Components:
7
+
8
+- 1x Toy DC Motor (like a 130 or 230 motor) - [[dc-motor-dat]]
9
+- 1x [[ULN2003-dat]]
10
+- 1x Diode-protected external power supply (e.g., 6V or 12V)
11
+- 1x Microcontroller (e.g., Arduino)
12
+
13
+Wiring:
14
+
15
+1. Connect motor one end to **+V (e.g. 6V)**
16
+2. Connect other motor end to **ULN2003 output (e.g., OUT1)**
17
+3. Connect **IN1** of ULN2003 to your microcontroller output pin
18
+4. Tie **GND** of ULN2003, microcontroller, and motor power supply together
19
+5. Connect **COM pin** of ULN2003 to motor **+V** (for flyback protection diodes)
20
+
21
+When IN1 is HIGH, the ULN2003 will pull OUT1 to GND, allowing current through the motor and it will spin.

11
+Overview
12
+
13
+The LV8548MC is a 2-channel low saturation voltage forward/reverse motor driver IC.
14
+
15
+It is optimal for motor drive in 12V system products and can drive either two DC motors, one DC motor using parallel connection, or it can drive a stepper motor in Full-step and Half-step.

+## 130 Motor Overview
5
+
6
+The **130 motor** is a type of **DC motor** commonly used in toys, small appliances, and DIY electronics projects.
7
+
8
+### 🔧 Type
9
+
10
+- **Type:** Permanent Magnet Brushed DC Motor
11
+- **Category:** Small-size DC Motor
12
+
13
+### ⚙️ Specifications (Typical)
14
+
15
+- **Voltage Range:** 1.5V – 6V (Commonly 3V or 5V)
16
+- **High RPM:** Often from a few thousand to over 10,000 RPM
17
+- **Low Torque:** Suitable for light-load applications
18
+- **Brush Type:** Brushed (uses carbon brushes and a commutator)
19
+
20
+
21
+## 230 Motor Overview
22
+
23
+The **230 motor** is a small **DC motor**, similar in design to the 130 motor but typically **larger in size and power**.
24
+
25
+### 🔧 Type
26
+
27
+- **Type:** Permanent Magnet Brushed DC Motor
28
+- **Category:** Medium-size DC Motor
29
+
30
+### ⚙️ Specifications (Typical)
31
+
32
+- **Voltage Range:** Often 3V – 12V
33
+- **Higher Torque and Power** than 130 motor
34
+- **Medium RPM** (usually lower than 130 motor, but stronger)
35
+- **Brush Type:** Brushed (uses carbon brushes)
36
+
37
+## Why Is It Called a "230 Motor"?
38
+
39
+The name **"230 motor"** comes from an informal naming convention based on the **size of the motor case**, not the voltage or power.
40
+
41
+### 📐 Meaning of "230"
42
+
43
+- **"2"** = Series or form factor group
44
+- **"30"** = Approximate **length of the motor case in millimeters** (~30 mm)
45
+
46
+So, a **230 motor** typically has:
47
+- **Diameter:** ~24 mm
48
+- **Length:** ~30 mm
49
+
50
+## 📊 Size Comparison Table
51
+
52
+| Motor Name | Diameter (mm) | Length (mm) | Power Level | Common Use |
53
+|------------|----------------|--------------|-----------------------|---------------------------------|
54
+| 130 | ~15.5 | ~20 | Small / Light-duty | Toys, small fans |
55
+| 230 | ~24 | ~30 | Medium | DIY cars, small robots |
56
+| 260 | ~24 | ~36 | Medium-High | Hobby motors, gear motors |
57
+| 280 | ~24 | ~45 | High | RC cars, small drills |
58
+| 380 | ~28 | ~50–60 | Very High | Power tools, electric screwdrivers |
59
+| 540 | ~36 | ~50 | Ultra High | RC racing cars, e-bikes |

35
+### # ✅ Common Features of DC Motor Driver Chips
36
+
37
+These are essential or desirable features for a DC motor driver IC, especially for brushed DC motors (like 130/230 motors):
38
+
39
+### 🔁 1. Bidirectional Drive
40
+- Allows motor to rotate **clockwise (CW)** and **counter-clockwise (CCW)**
41
+- Requires an **H-bridge** circuit internally
42
+
43
+### 🎚️ 2. PWM (Pulse Width Modulation) Support
44
+- Enables **speed control** by adjusting duty cycle
45
+- Most drivers support PWM input on EN or IN pins
46
+
47
+### 🧠 3. Input Logic Compatibility
48
+- Accepts standard **3.3V or 5V** logic signals from microcontrollers (Arduino, Raspberry Pi, ESP32, etc.)
49
+
50
+### 🔐 4. Built-in Protection Features
51
+- **Overcurrent protection**: Prevents damage from short circuits or heavy loads
52
+- **Thermal shutdown**: Protects the IC from overheating
53
+- **Undervoltage lockout**: Disables the chip if supply voltage drops too low
54
+
55
+### 📈 5. Current Rating
56
+- Should handle the **motor's stall current** without damage (e.g., 1A+ for 230 motor)
57
+
58
+### 🧲 6. Brake Mode (Optional)
59
+- Allows fast motor stop by shorting terminals
60
+- Useful for precise or quick motion control
61
+
62
+### 🔄 7. Sleep or Enable Pin
63
+- Allows putting the driver in low-power mode or turning off the motor without cutting power
64
+
65
+### 🔌 8. Separate Motor and Logic Supply
66
+- Often supports **dual power rails** (e.g., 5V logic and 6–12V motor power)
67
+
68
+### ⚡ 9. Flyback Diodes (Freewheeling Diodes)
69
+- Either **built-in or required externally**
70
+- Protects the driver from voltage spikes caused by motor inductance
71
+
72
+### 🧩 10. Compact Footprint / Module Availability
73
+- Available as SMD ICs or in **breakout boards** for prototyping
74
+
75
+### 📘 Bonus Features (Advanced Chips)
76
+- **Current sensing** output (e.g., DRV8871)
77
+- **I2C/SPI control** (e.g., DRV8830 has I2C)
78
+- **Phase/Enable or IN1/IN2 logic modes**
79
+- **Soft start** / controlled acceleration
