qiaoyang QY-BTUSB280 Single Tone Bluetooth Audio Receiving Module
Product Information
- The module is designed for audio signal processing in IoT devices. It has left and right channel output for the audio signal, an audio control function for volume level adjustment, and a power supply of 5V DC. The module can operate within a temperature range of -40 to 85 degrees C and is equipped with an embedded PCB antenna.
- The module complies with part 15.247 requirements for Modular Approval set forth by FCC rules. The PIFA antenna type used in the module has a maximum peak gain of -0.58dBi.
Product Usage Instructions
- The module can be used in IoT devices that require audio signal processing. The input voltage to the module should be nominally 5V DC. Ensure that only the embedded PCB antenna is used, as any other external antenna is prohibited.
- Use the left and right channel outputs (DACL and DACR) to connect to speakers or other audio output devices. Use AGND for audio signal ground. Use ADKEY for adjusting the volume level and other audio controls. The AD value detection pin can be used for detecting AD values.
- Ensure that the device using the module complies with FCC radiation exposure limits set forth for an uncontrolled environment. Avoid co-locating or operating the device in conjunction with any other antenna or transmitter.
- If the module is installed in a host device for portable usage, additional RF exposure evaluation may be required as specified by 2.1093.
- If the module is installed in a host device, ensure that the FCC
- An ID label is visible either through a window on the final device or on the outside of the final device in case the label is not visible otherwise. The FCC ID to be used is 2A8VN-QY-BTUSB280, which can only be used when all FCC ID compliance requirements are met.
INSTALLATION INSTRUCTION
This module is a single-tone Bluetooth audio-receiving module. The power supply voltage of the module is 5V. When the power supply is provided to the module, the module will work immediately. The mobile phone or tablet smart terminal can search the device name: QY-BTSP through Bluetooth, and then click to connect. After the connection is successful, the audio source of the smart terminal can be received through the Bluetooth module and then converted to analog audio signal output. The analog audio signal is connected to the power amplifier and speaker and then broadcast. The module also has an AD control interface, which can control the two-way up and down music and volume.
The specific module pin description is as follows:
- DACL: audio signal left channel output
- AGND: audio signal ground
- DACR: audio signal right channel output
- ADKEY: Audio control (up and down, volume level) function AD value detection pin
- GND: Power supply
- 5V: Module power supply
FCC Statement
- Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
- This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
- This device may not cause harmful interference, and
- This device must accept any interference received, including interference that may cause undesired operation.
OEM Guidance
- Applicable FCC rules
- This module has been tested and found to comply with part 15.247 requirements for
- Modular Approval.
- The specific operational use conditions
- This module can be used in IoT devices. The input voltage to the module is nominally 5V DC. The operational ambient temperature of the module is – to 5 degree C. Only the embedded PCB antenna is allowed. Any other external antenna is prohibited.
- Limited module procedures N/A
- Trace antenna design N/A
- RF exposure considerations
- This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment
- This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.If the device built into a host as a portable usage, the additional RF exposure evaluation may be required as specified by 2.1093.
- Antenna
- Antenna type : PIFA Antenna; Antenna Max. Peak Gain-0.58dBi
- Label and compliance information
- When the module is installed in the host device, the FCC ID label must be visible through a window on the final device or it must be visible when an access panel, door, or cover is easily removed. If not, a second label must be placed on the outside of the final device that contains the following text: “Contains FcC ID:2A8VN-OY-BTUSB280
- The FCC ID can be used only when all FCC ID compliance requirements are met.
- Information on test modes and additional testing requirements
- a) The modular transmitter has been fully tested by the module grantee on the required number of channels. modulation types, and modes, it should not be necessary for the host installer to re-test all the available transmitter modes or settings. It is recommended that the host product manutacturer, installing the modular transmitter, perform some investigative measurements to confirm that the resulting composite system does not exceed the spurious emissions limits or band edge limits (e.g., Where a different antenna may be causing9 additional emissions).
- b) The testing should check for emissions that may occur due to the intermixing of emissions with the other transmitters, digital circuitry, or due to the physical properties of the host product (enclosure). This investigation is especially important when integrating multiple modular transmitters where the certification is based on testing each of them in a stand-alone configuration. It is important to note that host product manufacturers should not assume that because the modular transmitter is certified that they do not have any responsibility for final product compliance.
- c) if the investigation indicates a compliance concern the host product manutacturer is obligated to mitigate the issue. Host products using a modular transmitter are subject to all the applicable individual technical rules as well as to the general conditions of operation in Sections 15.5, 15.15, and 15.29 to not cause interference. The operator of the host product will be obligated to stop operating the device until the interference has been corrected.
