New! Laird's BT85x and BT86x series HCI modules and adapter leverage the Cypress CYW20704 A2 chipset to provide exceptionally low power consumption with outstanding range for OEMs needing both Classic Bluetooth and Bluetooth Low Energy support. The Bluetooth v4.2 core specification shortens your development time and provides enhanced throughput, security and privacy. These modules are ideal when designers need both performance and minimum size. For maximum flexibility in integration, they support I2S and PCM audio interfaces, GPIO, and Cypress’ GCI coexistence (2-Wire). The modules provide excellent RF performance and identical footprint options for integrated antenna or an external antenna via a trace pin.
