Description
Our micro-sized Bluetooth module is one of the smallest form factors
available. The BT-22 is designed for maximum performance in a minimal
space and includes 4 general purpose input/output lines, several serial
interface options, analog-to-digital input, and up to 2M bps data throughput.
The BT-22 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.
