The MH-M28 Bluetooth module is a compact and versatile solution for adding wireless audio connectivity to your projects. Understanding the MH-M28 BLUETOOTH Datasheet is crucial for anyone looking to integrate this module into their DIY electronics, audio systems, or IoT devices. This document provides all the necessary technical specifications, pinouts, and usage guidelines to ensure successful implementation.
Understanding the MH-M28 BLUETOOTH Datasheet What it Holds and Why it Matters
The MH-M28 BLUETOOTH Datasheet serves as a comprehensive guide to the module’s capabilities and limitations. It contains critical information ranging from electrical characteristics and operating conditions to the physical dimensions and connection diagrams. This information is essential for proper circuit design, ensuring that the module operates within its specified parameters, and preventing damage due to overvoltage or incorrect wiring. Ignoring the datasheet can lead to unpredictable behavior or even permanent failure of the module. The datasheet generally includes:
- Pin Descriptions: Detailed explanation of each pin’s function.
- Electrical Characteristics: Voltage, current, and power consumption ratings.
- Bluetooth Specifications: Supported Bluetooth version and profiles.
- Dimensional Drawings: Precise measurements for integration into enclosures.
One of the primary uses of the MH-M28 BLUETOOTH Datasheet is to correctly identify the pinout of the module. The pinout diagram shows the function of each pin (e.g., power, ground, audio output, Bluetooth antenna connection). Connecting power or ground to the wrong pin can instantly destroy the module. It also describes the supported Bluetooth profiles, such as A2DP (Advanced Audio Distribution Profile) for streaming high-quality audio and AVRCP (Audio/Video Remote Control Profile) for controlling playback. Knowing these profiles will help you determine the module’s compatibility with different devices. Here is a simplified example of what you might find in a datasheet table:
| Pin Name | Description |
|---|---|
| VCC | Power Supply (3.3V-5V) |
| GND | Ground |
| L | Audio Output (Left Channel) |
| R | Audio Output (Right Channel) |
Furthermore, the MH-M28 BLUETOOTH Datasheet outlines the recommended operating conditions, including the voltage range, temperature range, and maximum current draw. Adhering to these specifications is crucial for ensuring the module’s stability and longevity. The datasheet also provides information about the module’s Bluetooth specifications, such as the Bluetooth version it supports (e.g., Bluetooth 4.2, Bluetooth 5.0) and the supported audio codecs (e.g., SBC, AAC). This information helps you understand the module’s audio quality capabilities and its compatibility with different Bluetooth devices.
