Laird's BT85x series of USB HCI modules and adapter leverage the Cypress CYW20704 chipset to provide exceptionally low power consumption while maintaining outstanding range for OEMs needing both classic Bluetooth and Bluetooth low energy support. The Bluetooth v4.2 core specification reduces development time and provides enhanced throughput, security, and privacy. These are ideal for designers who need both performance and minimum size. For maximum flexibility in integration, they support a host USB interface, I²S and PCM audio interfaces, GPIO, and Cypress’ Global Coexistence Interface (GCI 2-wire). These modules provide excellent RF performance and identical footprint options for integrated antenna or an external antenna via a trace pin. The BT85x modules present a Bluetooth standard HCI interface with native support for Windows, Linux, and Android Bluetooth software stacks for operating system backed devices. The BT851 pluggable USB adapter with inbuilt Bluetooth stack simply plugs into any Windows, Android, or Linux device via external USB connection.
