Comparison of the functionality HC05/HC06 and BLM-BT04-E02 wireless modules

 HC05 and HC06 are easy to use wireless modules, very popular in the market,but the version are old,it’s Bluetooth 2.0,some functions couldn’t meet customer’s requirements.

There is a higher version module BLM-BT04-E02 could replace HC-05 and HC-06 with better performance,following as a comparison chart:

In comparison,these 3 modules with same size,BLM-BT04-E02 could be pin to pin compatible for HC-05 and HC-06 .Actually also compatible for HC-02 .

For Bluetooth vesion,BLE-BT04-E02 is a dual mode mosule,it’s SPP3.0,+BLE 4.2,HC-05 and HC-06 are SPP2.0.

For transmit range,our BLE-BT04-E02 is longer.

Our BLM-BT04-E02 support iphone,and HC-05 and HC-06 couldn’t support it.

BLM-BT04-E02 with lower consumption.

And our BLM-BT04E also have TTL type board,support 3.3-6V level voltage, it can be directly connected to most 5V microcontrollers.
