1. General Introduction
1.1 Brief Introduction
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 can
directly drive a 250mW/8ohm speaker. The radio frequency part provides a sensitivity of -98dBm, which greatly
improves the wireless distance.
