FSC-BT2044GI Small-Size Low-Power BLE 5.1 Module Master&Slave

FSC‑BT2044GI is a compact, ultra‑low‑power Bluetooth 5.1 module supporting BLE and SIG Mesh protocols. It operates with extremely low sleep and active currents, making it ideal for battery‑powered applications such as Bluetooth keys, voice remote controllers, OBU, and smart home devices.

 

The module can be configured as either master or slave and features configurable output power. Preloaded with Feasycom’s easy‑to‑use firmware, it allows developers to access full Bluetooth functionality through simple ASCII commands over a serial interface, significantly simplifying integration and accelerating time‑to‑market.
