Bluetooth Module or BLE Module – What Suits Your Project?
The term Bluetooth covers two fundamentally different technologies today, each the right choice depending on the application.
- Classic Bluetooth is suited for applications requiring continuous data transmission and higher throughput – such as serial communication or audio. Modules like the HC-08 are easy to address via UART, making them particularly Arduino-friendly.
- Bluetooth Low Energy (BLE) is the more modern variant and today’s standard in the IoT space. BLE modules transmit smaller data packets at minimal power consumption. They are ideal for sensors, wearables, beacons, and battery-powered devices. The AI-Thinker modules in this shop predominantly support BLE 5.0 and can be flexibly integrated into custom designs.
Many modules combine BLE with Wi-Fi, offering a clear advantage when your project requires both communication paths.
Bluetooth Modules for Arduino, Raspberry Pi & Microcontrollers
Arduino Bluetooth Modules
For Arduino projects, a classic UART Bluetooth module like the HC-08 is recommended – it communicates directly via the serial interface without any additional libraries. For more demanding BLE projects, the AI-Thinker Development Boards offer a powerful alternative with significantly more processing power and connectivity.
Raspberry Pi Bluetooth Modules
While Raspberry Pi boards come with integrated Bluetooth, they quickly reach their limits in professional applications. A dedicated Bluetooth module extends the range, improves reliability, or adds BLE 5.0 capabilities to your system.
Bluetooth Module for Microcontrollers
For integration into custom microcontroller designs, compact AI-Thinker modules such as the PB-02, TB-03F, or ESP-C3-13 are available. They combine a powerful Bluetooth chip with an integrated processor and are also available as reels for series production.
AI-Thinker – The Manufacturer Behind the Modules
The majority of Bluetooth modules in our shop come from AI-Thinker, a manufacturer specialising in wireless modules with a broad portfolio. From simple BLE modules to combined Wi-Fi and Bluetooth chips, AI-Thinker covers virtually every use case. Individual units are available for prototyping, as well as reel orders for series manufacturing.
