The Arduino Bluetooth Module HC-06 (CSR Chip) is a compact and cost-effective solution for adding wireless communication to your microcontroller projects. Based on CSR BC04 Bluetooth technology, it operates as a Slave-only device, making it ideal for communication between an Arduino and smartphones or Bluetooth-enabled controllers. With a built-in 2.4GHz PCB antenna, it offers up to 10 meters of reliable wireless range. This module uses a UART serial communication interface and supports a voltage range from 3.3V to 6V, with a default baud rate of 9600 bps. Whether you’re building a remote-controlled robot, logging sensor data, or integrating home automation, the HC-06 provides stable and simple Bluetooth connectivity. Featured By RoboticsBD.

One of the easiest ways to spot the difference between an original HC-06 module and a clone lies in the Bluetooth chip size and quality.
The original HC-06 uses a genuine CSR chip, which is slightly larger and provides more reliable Bluetooth communication, better range, and full AT command support.
Clone versions often come with smaller, unbranded chips, even falsely labeled as "CSR". These clones may lack proper protocol support, have limited AT commands, and exhibit unstable or slow connections.
Backed by a reliable CSR chipset
Better signal stability and communication range
Compact and easy to integrate into projects
Ideal for Arduino and microcontroller applications
Full support for configuration and firmware upgrades
| Feature | CSR Chip (Genuine) | Clone CSR Chip (Chinese or non-genuine) |
| Chipset | Original CSR (Cambridge Silicon Radio) UK chip | Copy or alternative low-cost chipset |
| Stability | High – better signal strength, less dropout | Lower – occasional pairing issues or dropouts |
| AT Command Reliability | Fully supported and well-documented | Sometimes inconsistent AT command behavior |
| Firmware Upgradability | Often upgradeable | Often locked or unreliable firmware |
| Price | Slightly higher | Cheaper |
| Module Name | HC Type | Chip Quality | Key Notes |
| 1. HC-05 CSR Chip | HC-05 | Generic CSR | May be reliable if true CSR, but unverified origin |
| 2. HC-05 Genuine CSR Chip | HC-05 | Genuine | Best quality among HC-05, fully supports Master/Slave |
| 3. HC-05 Clone CSR Chip | HC-05 | Clone | Might face instability, but works for basic use |
| 4. HC-06 CSR Chip | HC-06 | Generic CSR | Slave only, check CSR chip authenticity |
| 5. HC-06 Genuine CSR Chip | HC-06 | Genuine | Best among HC-06, reliable slave communication |
| 6. HC-06 Clone CSR Chip | HC-06 | Clone | Basic functionality, lower reliability |
