Description
The added class 1 power, +16dBm, of the BT-11, gives this module one of
the best ranges in the industry. It’s completely pin compatible with the lower
power BT-21, and offers a second power choice on the same design.
The BT-11 module includes 16 general purpose input/output lines, several
serial interface options, analog-to-digital inputs, and up to 2M bps data
throughput.
The BT-11 is a surface mount PCB module that provides fully embedded,
ready to use Bluetooth wireless technology. The reprogrammable flash
memory contains embedded firmware for serial cable replacement using the
Bluetooth SPP profile. Other popular Bluetooth profiles, such as OBEX, are
also available.
Customized firmware for peripheral device interaction, power optimization,
security, and other proprietary features may be supported and can be
ordered pre-loaded and configured.
