FSC-BT909 is a class1 dual-mode Bluetooth module ( with BR/EDR & LE support simultaneously ). It can transmit over 500m with an integrated antenna. While using external whip antenna, the distance can be extended over 2000m. With AT+ programming interfaces, designers can easily customize their applications with supporting different Bluetooth profiles, such as A2DP, AVRCP, HFP/HSP, SPP, HID, GATT, and etc.
Features:
CSR8811 chipset
Bluetooth 4.2/4.1/4.0/3.0/2.1/2.0/1.2/1.1 support
Class 1 (signal power up to +18dBm)
Profiles including A2DP, AVRCP, HFP/HSP, SPP, GATT
Built-in ceramic chip antenna, external antenna optional
