FSC-BT634 Nordic nRF52840 SoC BLE 5.4 Module for Bluetooth Mesh & NFC & Thread & Matter & Zigbee


FSC-BT634 is bead on nRF52840.It has protocol support for Bluetooth LE, Bluetooch mesh, Thread, Zigbee, 802.15.4, NFC and 2.4GHz proprietary stacks

The FSC-BT634 is a Thread certified component and as such is ideal for home networking products using the Threadmeash stack.This means it is suitable for developing products for the Matter connected home ecosystem. The radiosupports 802.15.4 PHY and MAC layers and makes it suitable for additional stacks using 802.15.4 such as Zigbee.By default, FSC-BT634 module is equipped with powerful and easy-to-use Feasycom firmware. lt's easy-to-use and completely encapsulated. Feasycom firmware enables users to access Bluetooth functionality with simple ASClI commands delivered to the module over serial interface - it's just like a Bluetooth modem.It supports Wirepas Mesh protocal

Therefore, FSC-BT634 provides an ideal solution for developers who want to integrate Bluetooth wireless technology into their design.
