QCC300X series:

bluetooth 5.0 version, with flash , dual mode bluetooth chip, the most commonly used chip of qualcomm, relatively cost-effective bluetooth chip.


Now the market prefer to use QCC300X chip to replace previous ROM version of bluetooth chip, but the flash version of the development is relatively difficult, difficulty is now in the market we do not have too many relatively mature development technology company, many also just do ordinary bluetooth audio, replace the previous ROM version of the module, always with low data transmission speed and many of them do not have serial port.
