The At 09 Datasheet is your key to understanding and effectively using the popular Bluetooth module, often employed in DIY electronics projects, hobbyist endeavors, and even some commercial applications. It provides all the technical specifications, operating characteristics, and pinout information needed to integrate the At-09 module seamlessly into your project. This article will unpack the essential details found within the At 09 Datasheet, making it easier to navigate and implement this versatile component.
Decoding the At 09 Datasheet The Essentials
The At 09 Datasheet serves as the definitive guide for anyone working with the module. It contains detailed information about its electrical characteristics, such as operating voltage (typically 3.3V to 5V), current consumption, and transmission power. Understanding these parameters is crucial to avoid damaging the module and ensuring proper operation within your project. Furthermore, the datasheet specifies the module’s supported Bluetooth version (usually Bluetooth 4.0 BLE) and data transfer rates, allowing you to assess its suitability for your application. The ability to correctly interpret this information is critically important for avoiding potential hardware damage, optimizing power consumption, and choosing the appropriate communication protocols for successful integration.
One of the most important sections within the At 09 Datasheet is the pinout diagram. This diagram shows the physical arrangement of the module’s pins and their corresponding functions. Typically, you will find pins for power (VCC and GND), serial communication (TXD and RXD), and possibly other control or status pins. Correctly identifying and connecting these pins is essential for establishing communication between the module and your microcontroller or other devices. Incorrect wiring can easily lead to malfunction or even damage. For example:
- VCC: Power supply (3.3V to 5V)
- GND: Ground
- TXD: Transmit Data
- RXD: Receive Data
- STATE: Indicates the connection status
Beyond pin configurations, the At 09 Datasheet also usually includes information on the module’s supported AT commands. These commands are used to configure the module’s settings, such as its Bluetooth name, baud rate, and security parameters. The datasheet outlines each command’s syntax and function, enabling you to customize the module’s behavior to meet your specific project requirements. Sometimes, key characteristics are shown in table format for easy reference, such as:
| Parameter | Value |
|---|---|
| Operating Voltage | 3.3V - 5V |
| Bluetooth Version | Bluetooth 4.0 BLE |
| Transmission Power | 4 dBm |
