This article is compiled based on the product manual and official materials of the Ebyte (EBYTE) E104-BT52 series Bluetooth low-energy modules. It introduces in detail the CE, FCC, and SRRC international certifications obtained by the series, as well as the product models, core features, and differences between models.

The EWM105-WBS30S​ module, launched by EBYTE is a highly integrated 2.4GHz SoC wireless combo module that combines WiFi 6, BLE 5.2, and SLE 1.0 via a USB 2.0 interface — purpose-built to solve this core pain point. It integrates three mainstream wireless technologies on a single compact chip, offering device manufacturers a one-stop wireless connectivity solution.

According to the 2026-2032 China Industrial Wireless Communication Module Industry Status and Development Prospect Analysis Report (Industry Research Network, 2026), China's wireless module market size exceeded 48 billion yuan in 2025, with a compound annual growth rate of 17.2%.

Nel mondo di oggi in cui l’Internet of Things (IoT) e i dispositivi intelligenti sono onnipresenti, una sfida chiave nella progettazione dei prodotti è consentire a miliardi di sensori, dispositivi indossabili e prodotti per la casa intelligenti di funzionare in modo stabile per settimane, mesi o addirittura anni con una capacità limitata della batteria.

As the global population ages, ensuring the safety of seniors at home has become a critical concern. EBYTE’s Fall Detection Bracelet and Emergency Button offer a smart, wireless solution to detect falls and send instant alerts to caregivers or emergency services.

According to the 2024 Market Update by the Bluetooth Special Interest Group (SIG), global annual shipments of Bluetooth devices will exceed 7 billion units by 2025, with Bluetooth Low Energy (BLE) accounting for over 65% of the market (Source: Bluetooth SIG, 2024). ABI Research further predicts that Bluetooth penetration in industrial IoT (IIoT) and medical devices will reach 28% and 19%, respectively, by 2025 (Source: ABI Research, 2024).

Bluetooth is a wireless communication technology designed for short-range connections and data transmission between devices. It plays a crucial role in devices like wireless earbuds, smartwatches, smart home systems, and other IoT applications. However, in certain scenarios, extending Bluetooth’s communication range may be necessary. Here’s how to achieve this

A Bluetooth hub is a device that allows multiple Bluetooth devices to connect and communicate with each other through a hub. Its main function is to expand the connection capabilities of Bluetooth devices, especially when multiple Bluetooth devices need to be connected.

Now more and more devices are beginning to use wireless protocols for communication, and compared with the bus-based smart home system, wireless has a series of advantages such as plug-and-play and no wiring. And wireless has many advantages over wired, which will not be explained here one by one.

Smart home connects various devices in the home through the Internet of Things technology, providing various control or timing control functions and means. Compared with ordinary homes, smart homes not only have traditional home living functions, but also have building, network communication, information appliances, equipment automation functions, and provide all-round information interaction functions.

nRF52840 is a high-performance, multi-protocol wireless system chip (SoC) developed by Nordic Semiconductor, suitaBLE for Bluetooth low energy (BLE), ANT and 2.4GHz wireless applications. Known for its flexibility, powerful performance and low-power design, this SoC is ideally suited for a variety of application scenarios such as the Internet of Things (IoT), smart homes, wearaBLE devices, and wireless game controllers.

Bluetooth is a wireless communication technology designed to enaBLE different types of electronic devices to communicate and connect with each other within short distances. Bluetooth technology is constantly evolving and has multiple versions, each introducing new features and improvements. Common Bluetooth versions include Classic Bluetooth and Bluetooth Low Energy (BLE).

In previous articles, we have delved into many aspects of IoT gateways, a detailed review can be found at: [IoT Gateway & FAQ Guide]. This time, we will focus on the different classifications of IoT gateways, specifically, the comparative analysis between Zigbee gateways, LoRa gateways and Bluetooth gateways.

Bluetooth kit, Bluetooth amplifier and Bluetooth audio receiver are three different types of Bluetooth devices used in different application scenarios.

​This article will discuss the key differences between three prominent technologies in the IoT space - BLE, RFID, and UWB, explore their different use cases, and ultimately help determine which technology is better suited for a particular application. Before we dive into the differences, let's first take a look at the three wireless technologies and how they work.
