1. Overview

1.1 Introduction

E200-2G4A20S is a new wireless audio transmission module launched by
Chengdu EBYTE, transceiver all-in-one. It is characterized by small size, easy to
use, etc. It works in 2.4G frequency band, adopts hardware I/O to select channel
by default, and can also be set to software select channel by command, supports
MIC input and speaker output, and is compatible with 3.3V power supply
voltage.
The E200-2G4A20S integrates Microphone and Speaker PA amplifiers internally,
connecting directly to the microphone without the need for an external amplifier, and the audio output can directly drive
a 250mW/8ohm speaker with a maximum barrier-free transmission distance of around 300m.
The E200-2G4A20S adopts a frequency hopping mechanism, which can automatically switch among 3 channels, and can
effectively avoid being interfered by neighboring signals such as Wi-Fi or Bluetooth. In addition, the module also adopts
a low power consumption design, usually the standby current is only 12uA, which greatly extends the service life of
battery-powered devices.
