They integrate transparent transmission functionality for out-of-the-box use, supporting serial AT command sets. Users can access network functions via the serial port. This series is widely used in wearable devices, home automation, home security, personal health care, smart appliances, accessories and remote controls, automobiles, lighting, industrial Internet of Things, and other fields.

E103 Series WiFi Router Modules

The E103 series WiFi router modules currently include three products. The E103-W20 series WiFi modules are cost-effective and low-power IoT modules based on MediaTek's MT7688AN and MT7628AN chip solutions. They expose all interfaces of MT7688AN/MT7628AN, support OpenWrt OS and custom development, with rich interfaces and powerful processors. They are widely used in smart devices or cloud service applications and allow free secondary development. The EWM103-WF7621A wireless router module is a gigabit router gateway module developed by EBYTE based on MediaTek's MT7621A chip solution. It integrates a dual-core MIPS-1004Kc (880MHz), HNAT/HQoS/Samba/VPN accelerator, and a 5-port GbE switch. It supports OpenWrt OS and custom development, with rich interfaces and powerful processors, suitable for smart devices or cloud service applications and allowing free secondary development.

E103 Series General-Purpose Modules

The E103 series general-purpose modules not only have rich peripheral interfaces but also possess powerful neural network computing and signal processing capabilities. They are cost-effective and suitable for various application scenarios in the AIoT field, such as wake-up word detection and voice command recognition, face detection and recognition, smart control panels, smart speakers, etc.

E103 Series WiFi Mesh Modules

In EBYTE's solution, the modules supporting WiFi Mesh (with or without router networking) are the E103-W07 series WiFi mesh networking modules. E103-W07 is a network protocol built on the Wi-Fi protocol. Espressif's ESP-MESH allows a large number of devices distributed over a wide area (indoor and outdoor) to connect to each other in the same WLAN (Wireless Local Area Network). E103-W07 features self-organizing and self-healing properties, meaning the mesh network can build and maintain itself autonomously.

E101 Series WiFi Module Selection Parameter Guide

The E101 series dual-mode Bluetooth WiFi modules are all developed based on ESP32 series chip solutions. They integrate transparent tramission functionality for out-of-the-box use, supporting serial AT command sets and server AT command sets. Users can access network functions via the serial port. The following table is the selection table for this series of dual-mode WiFi modules.

Note: The above modules are pin-compatible with original modules and come with relevant test kits.

IoT Application Solutions of WiFi Modules

WiFi Module in Smart Home Field

The smart home appliance system is mainly based on WiFi IoT technology to realize intelligent control of home devices. The main working principle of WiFi smart home is: the user's mobile phone sends program instructions, the home system module receives and processes the information appropriately, then the processing result is transmitted to the microcontroller via WiFi, so that the microcontroller can issue corresponding control instructions according to the information to complete the user's command, and at the same time feed back the final processing result to the client.

WiFi Module in Industrial Remote Control and Telemetry Solution

As an extension and supplement to traditional WiFi technology, WiFi modules can provide a unique combination of security, long distance, low power consumption, and highly optimized wireless connections, greatly improving the management efficiency of factory automation.

Application of WiFi Modules in TCP Server

A WiFi module establishes a TCP Server in AP mode, and other modules establish TCP Clients in STATION mode to communicate with it; this networking model can be referred to as intra-module networking. A module in AP mode can connect up to 8 STATIONS, meaning there can be up to 9 module devices in the network. Under the condition of completing intra-module networking, the TCP Server can be established on any module, and the remaining 8 WiFi modules can use TCP Clients to communicate with it (but no more than 5 clients can access the TCP server simultaneously).

That's all for today's sharing. EBYTE is committed to better enabling the development of IoT, intelligence, and automation every day, and improving resource utilization.
