The Bluetooth Modules are designed for ultra-low-power wireless applications. They offer the lowest power consumption in the industry, enabling advanced features while optimizing size and battery life. With a dual-core architecture and 2.4 GHz transceiver, they support Bluetooth Low Energy and custom protocols. They facilitate rapid development with abstraction, drivers, and sample applications.
