The wireless audio transmission module enables audio signals to be transmitted wirelessly without a physical connection. These modules usually use different wireless technology standards such as Bluetooth, Wi-Fi, 2.4GHz ISM band, and RF (Radio Frequency) to realize the wireless transmission of audio signals.
E200-2G4A20S is a new wireless audio transmission module launched by Yibaite, which integrates transceiver and receiver. It has the characteristics of small size and easy to use, works in the 2.4G frequency band, adopts hardware I/O to select the channel by default, and can also be set to software to select the channel through instructions, supports MIC input and speaker output, and is compatible with 3.3V power supply voltage.
Core features:
The 2.4G wireless audio module operates in the 2.4GHz frequency band and can provide a long transmission distance (more than 100 meters in open area). The maximum barrier-free transmission distance of the E200-2G4A20S is about 300m, which is suitable for applications that require a certain transmission range but do not need Bluetooth compatibility.
The E200-2G4A20S adopts a frequency hopping mechanism, which can automatically switch between 3 channels, which can effectively avoid being interfered by surrounding Wi-Fi or Bluetooth signals, and the signal is stable and penetrating.
The E200-2G4A20S integrates a microphone and speaker PA amplifier, which can be directly connected to the microphone without an external amplifier, and the audio output can directly drive 250mW/8ohm speakers.
In addition, the module is designed with low power consumption, with a typical standby current of only 12uA, which greatly extends the life of battery-powered devices.
Support one-to-one audio transmission, two-way transmission can be real-time intercom; The master-slave mode can be switched in real time, which is more flexible.
By default, the working channel is controlled by the channel pin, and the working channel can also be controlled by software commands after setting, which is easy to use.
It also supports AT command configuration, supports 2.2~3.6V power supply, and more than 3.3V power supply can ensure the best performance. Industrial-grade standard design, support long-term use at -40~+85°C. Dual antennas are optional (IPEX/stamp holes), which is convenient for users to redevelop and facilitate integration.
The wireless audio module is used in a wide variety of applications, including mobile communications, the construction industry, public address systems, conference systems, and security alarms.
The E200 series wireless audio module also supports the E200-470A17S and E200-900A17S in the working frequency bands of 470~510MHz and 863~928MHz ISM frequency bands, which supports one-to-many broadcast transmission, and also integrates microphone input and speaker output, and can be switched quickly in the integration of transceiver and receiver.
