Description
The BT-STA2425 is a flexible low-power module
enabling Bluetooth^® connectivity. It is fully
programmable and capable of running the whole
stack plus custom applications.
The ARM7^® embedded microcontroller can be
either programmed by the end-user or flashed
with our selection of firmware images, thereby
turning the module in a complete solution for
wireless audio connectivity or serial port
replacement.
A full set of peripherals is also available to allow
– A2DP, AVRCP sink and source
simple interfacing with other devices in the
– HFP/HS
system.
– SPP (up to 7 simultaneous connections
– Additional profiles under development
Order code: BT-STA2425
! Seamless connection with ST audio codecs
and amplifiers (STA529, STA333BW,STA328)
