Description
ST Bluetooth Modules are highly integrated for
easy implementation in embedded applications.
Class 2 modules enable wireless communication
with other Bluetooth enabled devices up to 10 m
away. The GS-BT2416C2 integrates on a unique
FR4 PCB support: BT 1.2 radio and baseband,
memory, 32 KHz and 13 MHz oscillators, as well
Vreg. The antenna has not been included in order
to grant a degree of freedom to the user in
selecting the most suitable design and placement
between external and integrated antenna that
could be SMA aerial or a low cost antenna trace
designed on PCB. For more details please refer
to GS-BT2416C2DB Application Note. Modules
are coming without any SW to offer a further
freedom degree to user that can embed his own
solution or any available BT certified SW upon his
choose and preference.
