CB-OBS421X-I4

RF Transceiver Modules And Modems Overview

The CB-OBS421X-I4 is a Bluetooth v4.0 dual-mode module based on the Texas Instruments CC2564 radio and STMicroelectronics STM32F10x microprocessor. It supports Classic Bluetooth (BR/EDR) and Bluetooth Low Energy (BLE). The module features an embedded protocol stack including SPP, DUN, PAN, and GATT profiles. It offers a throughput of up to 1.3 Mbps and advanced multipoint connectivity supporting seven slaves. An integrated low emission mode limits interference with other 2.4GHz RF signals.
