USB (Universal Serial Bus) is a widely used technology for connecting devices to personal computers. The USB Mini connector, also known as Mini-USB, is a smaller version of the standard USB connector, and is commonly found on portable devices such as cameras and smartphones.
Understanding the USB Mini Connector
The USB Mini connector comes in two different types – Type A and Type B, both of which have different wiring arrangements. Type A has four pins, while Type B has five pins.
The wiring diagram for the USB Mini connector differs depending on the type of connector. In this article, we will explore the wiring diagram for both types of USB Mini connectors. We will also discuss the applications and usage of USB Mini connectors, as well as answer some frequently asked questions.
Type A USB Mini Wiring Diagram
The Type A USB Mini connector has four pins. These pins are arranged in a rectangular shape, with two pins on top and two on the bottom. The pins are numbered 1 through 4, starting from the left-hand corner at the top. The wiring diagram for the Type A USB Mini connector is as follows:
| Pin Number | Signal | Color Code |
|---|---|---|
| 1 | VCC | Red |
| 2 | Data- | White |
| 3 | Data+ | Green |
| 4 | Ground | Black |
Pin 1 – VCC
Pin 1 is responsible for providing power to the device. This pin is connected to the USB host, and should provide a voltage of 5V. The voltage can range from 4.5V to 5.5V.
Pin 2 – Data-
Pin 2 is responsible for transmitting data from the device to the host. This pin is connected to the USB host, and should provide a voltage of 0V when not in use.
Pin 3 – Data+
Pin 3 is responsible for transmitting data from the host to the device. This pin is connected to the USB host, and should provide a voltage of 0V when not in use.
Pin 4 – Ground
Pin 4 is responsible for providing a common ground for the device and the host. This pin is connected to the USB host, and should be at 0V.
Type B USB Mini Wiring Diagram
The Type B USB Mini connector has five pins. These pins are arranged in a square shape, with four pins on the bottom and one on the top. The pins are numbered 1 through 5, starting from the left-hand corner at the top. The wiring diagram for the Type B USB Mini connector is as follows:
| Pin Number | Signal | Color Code |
|---|---|---|
| 1 | VCC | Red |
| 2 | Data- | White |
| 3 | Data+ | Green |
| 4 | ID | Brown |
| 5 | Ground | Black |
Pin 1 – VCC
Pin 1 is responsible for providing power to the device. This pin is connected to the USB host, and should provide a voltage of 5V. The voltage can range from 4.5V to 5.5V.
Pin 2 – Data-
Pin 2 is responsible for transmitting data from the device to the host. This pin is connected to the USB host, and should provide a voltage of 0V when not in use.
Pin 3 – Data+
Pin 3 is responsible for transmitting data from the host to the device. This pin is connected to the USB host, and should provide a voltage of 0V when not in use.
Pin 4 – ID
Pin 4 is an optional pin, and is used to identify the device. This pin is not used in most applications, and can be ignored in most cases.
Pin 5 – Ground
Pin 5 is responsible for providing a common ground for the device and the host. This pin is connected to the USB host, and should be at 0V.
