Generic 1D4 HSPP-C JDY-31 Bluetooth serial RF transceiver module features
Other Features
SPP bluetooth serial protocol support, low-cost, small size, low power consumption, high sensitivity in receiving signals, built-in PCB transceiving antenna, 6 pins (EN, VCC, GND, TXD, RXD, STATE), STATE pin for connection status, built-in LED for connection status
Instructions for Use/Warnings
Only apply for RX pin on the bluetooth module, Arduino boards such as Uno, Nano and Mega board or other microcontrollers output 5V at their I/O pins. You need to use a voltage divider (1K + 2K resistor network) or logic level shifter to step down the 5V signal from microcontroller to 3.3V before feed it into RX pin on bluetooth module. TX pin on the bluetooth module outputs 3.3V signal and Arduino can perceive this voltage as HIGH, so stepping up this signal voltage is not required. TXD : Transmitter pin, this pin must connect to RX pin of next device. RXD: Receiver pin, this pin must connect to TX pin of next device. Bluetooth signal strength can be significantly affected by the surrounding especially the conductivity of surfaces. Installing the bluetooth module within metal enclosures can severely affect the bluetooth signal. Avoid placing metallic object, surfaces or wire near the PCB antenna on the module. It can severely affect the module’s ability to receive signals.

Product details
Product description
SPP-C Bluetooth module Replace HC-05 HC-06 Description This bluetooth module is a working alternative for HC-05 or HC-06 at affordable price! This module utilizes UART serial interface protocol, so it can support SPP bluetooth serial protocol.
It is designed to be low-cost, small, low power consumption but has high sensitivity in receiving signals.
Datasheet Features Use Bluetooth version 2.1 + EDR Bluetooth Class 2 Built-in PCB transceiving antenna Supports UART interface Operating at 3.3V Specifications Operating Frequency Band 2.4 – 2.48 GHz unlicensed ISM band Bluetooth Specification V2.1 + EDR Output Power Class Class 2 Operating Voltage 3.3V Host Interface UART Operating Temperature 40 to +150?C Supply Voltage for VCC pin 5.6V (max) Operating Baud Rate 38400/115200 bps Notes Only apply for RX pin on the bluetooth module, Arduino boards such as Uno, Nano and Mega board or other microcontrollers output 5V at their I/O pins.
You need to use a voltage divider (1K + 2K resistor network) or logic level shifter to step down the 5V signal from microcontroller to 3.3V before feed it into RX pin on bluetooth module.
TX pin on the bluetooth module outputs 3.3V signal and Arduino can perceive this voltage as HIGH, so stepping up this signal voltage is not required.
Additional Information TXD : Transmitter pin, this pin must connect to RX pin of next device RXD: Receiver pin, this pin must connect to TX pin of next device There are 6 pins on this module, namely EN, VCC, GND, TXD, RXD, STATE.
When the module is paired connection to a device (such as mobile phone), STATE pin will output HIGH, otherwise it will output LOW signal.
The built-in LED on the module indicates the bluetooth connection, LED Blink Status Meaning Slowly Waiting for connection… Always on Connected Bluetooth signal strength can be significantly affected by the surrounding especially the conductivity of surfaces.
Installing the bluetooth module within metal enclosures can severely affect the bluetooth signal.
Avoid placing metallic object, surfaces or wire near the PCB antenna on the module.
It can severely affect the module’s ability to receive signals.
