FSC-BT976 BLE 5.1 SIG Mesh MCU Module with 10dBm Maximum Output Power

Tags: , ,

The Feasycom FSC-BT976 is a Bluetooth 5.1 Low Energy module that supports very low active RF and MCU current and low-power mode current consumption, providing excellent battery lifetime and allow for operation on small coin cell batteries and in energy-harvesting applications. FSC-BT976 contains a 32-bit MCU core Up to 64MHz clock speed up to 64KB system SRAM up to 512KB Flash storage supports dual wire debugging protocol It is sutable for a variety of RF spefication systems. FSC-BT976 module is equipped with powerful and easy-to-use Feasycom firmware. It'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, just like a Bluetooth modem. Therefore, FSC-BT976 provides an ideal solution for developers who want to integrate Bluetooth wireless technology into their design.
