Product Introduction: BLE 4.0 (Bluetooth Low Energy) Module with ROHS Certification

Core Features

• Low Power Consumption: Optimized power management design ensures ultra-low energy consumption—less than 10μA in sleep mode, approximately 250μA in broadcasting mode, and less than 10mA in connection mode. This makes it ideal for battery-powered devices that require long-term operation, such as wearable electronics and wireless sensors.

• Stable Wireless Connectivity: Operates on the 2.4GHz ISM free frequency band with GFSK modulation, supporting a communication distance of 50–150 meters in an open area (varies with transmission power and environmental conditions). It enables fast connection and stable data transmission, with a receiving sensitivity ranging from -90dBm to -98dBm.

• Standard Protocol Compliance: Fully complies with Bluetooth Core Specification v4.0, integrating GAP (Generic Access Profile), GATT (Generic Attribute Profile), ATT (Attribute Protocol), L2CAP (Logical Link Control and Adaptation Protocol), and SMP (Security Manager Protocol) stacks, ensuring compatibility with various BLE-enabled devices.

• Flexible Interface Design: Equipped with multiple interfaces including UART, GPIO, I2C, and SPI, supporting AT command configuration for easy integration with microcontrollers (MCUs) and other electronic components. It adapts to different PCB design requirements with various packaging options such as SMT (Surface Mount Technology), DIP, and stamp hole, with a compact size (e.g., 16×13mm) for space-constrained applications.

• ROHS Certification: Strictly adheres to the EU ROHS directive (Restriction of Hazardous Substances), restricting the use of six hazardous substances including lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr⁶⁺), polybrominated biphenyls (PBBs), and polybrominated diphenyl ethers (PBDEs), ensuring environmental safety and legal access to the EU market.
