HC-08 Bluetooth 4.0 BLE Serial Module w/ CC2540 Chip

Description

The HC-08 Bluetooth module implements the Bluetooth Low Energy (BLE) 4.0 protocol using the Texas Instruments CC2540 SoC, providing a robust wireless serial bridge. It operates in the 2.4GHz ISM band with GFSK modulation, achieving a sensitivity of -93dBm for reliable data links. The module is pre-configured for Serial Port Profile (SPP) operation, making it an industrial-grade replacement for wired serial cables.

Designed for flexible integration, the HC-08 supports a wide UART baud rate from 1200 to 115200 bps and is fully configurable via standard AT commands. Its low-power architecture features multiple sleep modes, with a deep sleep current as low as 0.4 microamps, making it ideal for always-on, battery-operated sensor nodes and remote control systems.
