Description
The JDY-31 SPP-C module implements the Bluetooth 2.0 protocol stack to provide a straightforward serial pass-through link. It operates in transparent mode, relaying data between its UART interface and Bluetooth radio without protocol overhead, making it a simple drop-in solution for adding wireless connectivity to microcontrollers and embedded systems.
Designed for low-power operation, the module consumes 4.7mA during active communication and supports a wide supply voltage range from 1.8V to 3.6V, accommodating various power sources. Its integrated PCB antenna provides a typical line-of-sight range of up to 30 meters, sufficient for short-range telemetry, remote control, and data logging applications.
