Original CSR Chip vs Clone – What’s the Difference?

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.

Why Choose the Original HC-06?

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

CSR Chip vs Clone (Chip Differences)

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

Summary of Bluetooth Modules available in RoboticsBD

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

Which Should You Use?

For advanced control (Master/Slave, Arduino to Arduino):

→ HC-05 Genuine CSR Chip

For simple, reliable communication (e.g., Arduino to Android):

→ HC-06 Genuine CSR Chip

For budget or experiments:

→ Clone modules are fine, but test each thoroughly.
