BT module Specification of LM-Q21-3031/3021 (based on QCC3031/3021) 1. Introduction The LM-Q21-3031/3021 is a Bluetooth single-mode module with a built-in PCB antenna. This is a compact and cost effective module capable of embedding into wired/wireless mono/stereo speaker applications. The LM-Q21-3031/3021 is built on top of the Qualcomm chip QCC3031/3021. The only difference between the two is that the QCC3031 supports Qualcomm ®aptX™ audio (while the QCC3021 does not).
