Overview

1. EJEAS MS20 Mesh Group Intercom System

EJEAS MS20 Mesh Group Intercom System

The EJEAS MS20 is a multi-hop mesh network intercom system designed for group communication, music sharing, and mobile phone integration, primarily for use in scenarios like motorcycle riding. It supports communication with up to 20 people across 5 channels, offering a maximum communication distance of about 2 kilometers. The system operates on a communication frequency of 470-488MHz, providing a longer transmission distance and better anti-interference ability compared to traditional Bluetooth chain intercoms. When participating in campaign mode as a listener, there is no limit to the number of people who can join the intercom in a listen-only manner.

Product Details:

The device features an antenna, an LED light (indicating Blue, Red, Green states), and several control buttons:

• M Button: Used for various functions including microphone mute/unmute, intercom pairing, and channel switching.
