1. Functional characteristics
LSD4BT212-06D0 is based on Broadcom Bluetooth chip
BCM20705, designed specifically for Hisense TV Bluetooth module, can
be widely applied in the field of short-range wireless communications for
all occasions, it has small size, low power consumption, transmission
distance, anti-interference ability, and low cost.
The module antenna is ceramic antenna, the overall design is
compact, small size, the interface is completely open, customers in the
use of RF hardware design eliminates the difficulty, while the software
and product structure more flexible secondary development of space.
