Bluegiga Legacy Modules (Classic)

Bluegiga Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR) and Bluetooth 4.1 (dual mode) modules are completely integrated, certified and high-performance radio frequency products that include all the necessary Bluetooth BR/EDR profiles for data and audio applications. The latest module is BT121, combining BR/EDR with Bluetooth Low Energy. For new Bluetooth 5 designs, we recommend our latest BGM and BGX Bluetooth Modules, based on our EFR32BG SoCs.
