Bluetooth BK3231 Transceiver Module HC-05 06 Compatible
The SPP-C Bluetooth module is a compact and reliable wireless data transmission solution designed for projects that require stable Bluetooth communication. Based on the Bluetooth V2.1+EDR protocol, it supports the Serial Port Profile (SPP) and communicates through a UART interface, making it easy to integrate with microcontrollers, development boards, and embedded systems. Its small size, low power consumption, built-in antenna, and high sensitivity make it ideal for DIY electronics, robots, sensors, and wireless monitoring applications.
