FSC-BT660 Small BLE 5.3 SIG Mesh & Matter/OpenThread Module

FSC-BT660 is ideal for mesh loT wireless connectivity using Matter or OpenThread, it delivering a maximum power output of +19.5 dBm, suitable for long range application. By default, FSC-BT660 module is equipped with powerful and easy-to-use Feasycom firmware. It’s easy t o use and completely encapsulated. Feasycom firmware enables users to access wireless functionality with simple UART AT commands delivered to the module over serial interface, just like a wireless modem. Therefore, FSC-BT660 provides an ideal solution for developers who want to integrate Bluetooth wireless technology into their design.
