FSC-BT634 is based on the Nordic nRF52840 and supports various protocols, including Bluetooth LE, Bluetooth mesh, Thread, Zigbee, 802.15.4, NFC, and 2.4GHz proprietary stacks. As a Thread certified component, it is suitable for home networking products and the Matter connected home ecosystem. The radio supports 802.15.4 PHY and MAC layers, making it compatible with additional stacks like Zigbee. Equipped with Feasycom firmware, the module offers simple access to Bluetooth functionality through UART AT commands. Thus, FSC-BT634 is an ideal solution for developers integrating Bluetooth wireless technology into their designs.
