The difference between QCC3034 and CSR8675 Bluetooth Module

 Many Bluetooth chips are facing shortages, including Qualcomm's CSR8675, CSR8645, QCC3007, QCC3008, etc.

Recently, many customers are consulting the CSR8675 Bluetooth audio module, but the chip of this Bluetooth module is currently in short supply. BLM World recommends that customers change to the QCC3034 audio module. What are the differences and similarities between these two modules? BLM World has CSR8675 module (BLM-BTM875) and QCC3034 module (BLM-BTM334), here is 2 modules information:

It can be seen from the above table that there is not much difference between the two audio modules, and the price of the Bluetooth module of QCC30334 is more favorable than that of CSR8675. CSR8675 was released several years earlier than QCC3034, and this chip will be discontinued earlier than qcc3034. Considering the long-term production of the product, BLM World's suggestion to use the QCC3034 chip would be better.
