FSC-BT3131 TI CC2340R5 MCU Bluetooth Low Energy BLE 5.3 Module


The Feasycom FSC-BT3131 is a wireless microcontroller (MCU) mainly focus on Bluetooth 5.3 low energy applications. Very low active RF and 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. It supports GAP, ATT/GATT, SMP L2CAP profiles. It integrates Baseband controller in a small package (Integrated chip antenna), so the designers can have better flexibilities for the product shapes.
