E200-470A17S is a new wireless audio transmission module, which integrates transceiver. It has the characteristics of small size and convenient use. It works in the frequency band (470.033 ～ 512.273MHz) (default 512.273MHz), uses hardware I/O to select channels, supports MIC input and speaker output, and is compatible with 3.3V and 5V power supply voltages. The E200-470A17S integrates a microphone (Microphone) and a speaker (Speaker) PA amplifier. Direct connection to the microphone does not require an external amplifier. The audio output candirectly drive a 250mW/8ohm speaker. The radio frequency part provides a sensitivity of -98dBm, whichgreatlyimproves the wireless distance. Compact and convenient, the E200-470A17S ensures balanced performance and sound quality with a high sensitivity of -98dBm for extended wireless coverage and a built-in microphone amplifier, eliminating the need for additional power. The versatility of the module allows for compatibility with both 3.3V and 5V power supply with a wide frequency band of 470.033-512.273MHz.
Features：The Audio Wireless Module UART Ebyte E200-470A17S is specially designed for mobile communication transmission. It supports one-to-many broadcast transmission, with an ideal communication distance of up to 300m. Control the working channel with the channel pin, and conveniently switch the master-slave mode in real time. Also, it supports a 3.0-5.5V power supply, and has an industrial standard design that supports long-term use at -40-85°C. Optional dual antennas (IPEX/stamp hole) support user development and integration.
Application：Smart home; Wireless alarm security system; Wireless audio transmission; Intelligent voice system;
