FSC-BT821 Super Small Size Bluetooth Low-Energy Module With Competitive Price

Product Overview:

FSC-BT821 is a fully integrated Bluetooth module that complies with Bluetooth 4.2 dual mode protocols(BR/EDR/BLE). It supports SPP, HID, GATT, iBeacon profiles. It integrates Baseband controller in a small package(Need an external RF antenna), so the designers can have better flexibility when designing the product shapes.
