ST Bluetooth Modules are highly integrated for easy implementation in embedded applications. Class 1 modules enable wireless communication with other Bluetooth enabled devices up to 100 m away. The GS-BT2416C1 integrates on a unique FR4 PCB support: BT 1.2 radio and baseband, memory, 32 KHz and 13 MHz oscillators, Vreg as well as PA function. The antenna has not been included in order to grant a degree of freedom to the user in selecting the most suitable design and placement between external and integrated antenna that could be SMA aerial or a low cost antenna trace designed on PCB. For more details please refer to GS-BT2416C1DB Application Note. Modules are coming without any SW to offer a further freedom degree to user that can embed his own solution or any available BT certified SW upon his choose and preference.
