FSC-BT641 BLE 4.2 Programmable Module with 13dBm Maximum Output Power

Categories:
FSC-BT641

The Feasycom FSC-BT641 is a Bluetooth Low Energy (BLE) 4.2 module with a 32-bit MCU microcontroller that can be used as an application processor as well as a data pump in fully hosted systems. It supports a wide range of applications from low-end, price sensitive designs to computing-intensive ones and provides advanced high-end features in economical products. Very low active RF, MCU current and low-power mode current consumption provide excellent battery lifetime and allow for operation on small coin cell batteries and in energy-harvesting applications. The BLE 4.2 firmware includes the L2CAP service layer protocols, Security Manager (SM), ATT, GATT and GAP.
