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
simple interfacing with other devices in the
system.
