BT900-US - Bluetooth Dual Mode USB dongle with Peripheral and Central mode

USB dongle provides Classic and Bluetooth Low Energy support to PC's, laptops and mobile computers. No external Bluetooth stack or drivers required!

The Laird BT900-US USB dongle has been developed to take advantage of the BT900-SA module, providing a simple and easy way to add Classic Bluetooth, BLE Central, and BLE Peripheral mode to virtually any operating system with a USB interface. Leverage the BT900-US to enable any Bluetooth SPP device or BLE sensor to communicate to any PC, laptop, or mobile computer without any complicated installation or software support requirements.

The BT900-US carries several modular FCC, IC, CE, and Bluetooth SIG approvals, meaning you don't need costly and time-intensive testing to bring certified Bluetooth to market. Certifications from worldwide regulatory bodies take time, effort, financial cost, and ultimately slow development. Laird's approvals extend to your design with no additional testing, making them a fast and efficient route to production.
