In industrial control, smart home, and automation sectors that demand ultimate response speed and easy integration, traditional "serial-to-wireless-to-serial" communication modes can no longer meet stringent real-time requirements。EBYTE has launched the EWM151-2G4T10S wireless synchronous transmission solution, which abandons conventional data packet protocol stacks and creates a new paradigm of "hardware level direct connection" for wireless transmission, enabling digital signals to achieve zero-latency synchronization like physical wires.

This solution consists of the EWM151-2G4T10S core module, EWM151-2G4T10SX (IPEX antenna version), and EWT151-2G4T10S test kit, providing users with a complete toolchain from rapid verification to in-depth integration.

Product Overview Of EWM151-2G4T10S / 2G4T10SX 

Both are 10×10 mm micro patch modules with standard 18-pin stamp hole packaging. Their only difference lies in antenna solutions: the EWM151-2G4T10S adopts a PCB on-board antenna for the simplest integration; the EWM151-2G4T10SX uses an IPEX 3rd-generation antenna connector, allowing users to connect external high-gain antennas to address longer-distance or more complex signal environment challenges. Both provide 4-channel DI (Digital Input) and 4-channel DO (Digital Output) hardware interfaces, with a reserved UART serial port for AT command configuration.

EWT151-2G4T10S (Evaluation Kit):

As a rapid development board based on the 2.4T10S module, it encapsulates all hardware complexities. The board comes with a pre-soldered module and integrates Type-C power supply/serial port, 4-channel input buttons, 4-channel output indicators, pairing/reset/wake-up buttons, etc. Users can perform function verification and distance testing immediately after power-on without any programming or external circuits, reducing development cycles from "weeks" to "minutes".

Technical Advantages: 

  • Ultra-Low Synchronization Latency (<30ms): Abandoning the data encapsulation-parsing process of software protocol stacks, it achieves pure hardware-level direct mapping and wireless synchronization of level signals. The signal synchronization time between DI and DO across modules is within 30 milliseconds, meeting the requirements of most real-time control scenarios.

  • Extremely Simple Usage Process: Core functions are "pair and use". After two modules are paired via buttons or AT commands, their 4-channel DI and DO automatically establish a one-to-one bidirectional synchronization relationship. Pressing a button on one side (triggering DI) will immediately light up the corresponding indicator on the other side (activating DO output), as intuitive and reliable as physical wiring.

  • Powerful and Reliable Performance: The measured communication distance in open areas can reach 300 meters. It supports wide-voltage power supply of DC 1.9V~4.2V (typical value 3.3V), with a transmission current of only 24mA and a sleep current as low as 1.5uA, balancing performance and power consumption.

  • Multiple Pairing and Intelligent Management: Supports three pairing methods: button, AT command automatic, and manual. In configuration mode (AT+MODE=0), users can query and set target addresses via AT commands to achieve precise point-to-point binding. Long-pressing the KEY pin for over 10 seconds can clear pairing information with one click and restore factory settings.

  • Industrial-Grade Quality Assurance: Operating temperature ranges from -40℃ to +85℃, using industrial-grade standard components and design to ensure long-term stable operation in harsh environments. It also supports serial port upgrade (IAP) capability for continuous optimization of future functions.

Typical Application Scenarios

  • Industrial Wireless Remote Control and Synchronous Control: Replaces bulky and easily damaged drag chain cables on equipment such as machine tools, cranes, and AGV robots to achieve wireless synchronization of multiple control signals. Multiple buttons on one transmitter can control multiple relays or solenoid valves on the receiver without latency.

  • Smart Home and Building Automation: Enables wireless synchronous group control of lights and curtains in multiple rooms. A switch panel at the door (integrated with DI) can wirelessly control multiple lamps in the living room and bedroom (connected to DO).

  • Wireless Alarm and Security Linkage: Signals from multiple door/window sensors (triggering DI) can be wirelessly synchronized to a central alarm host (activating DO sound and light alarms) or linked to other devices, significantly reducing wiring costs.

  • Educational Experiments and Creative Interaction: As a teaching module for IoT and electronic competitions, its intuitive "button-light" feedback mechanism helps students quickly understand the concepts of wireless communication and real-time control.

Selection and Development Recommendations

For new users or project preliminary verification, it is strongly recommended to start with the EWT151-2G4T10S test kit. Using two kits allows for an almost "out-of-the-box" experience to quickly verify whether communication distance and stability meet project requirements.

After confirming the feasibility of the solution, proceed to the product design phase:

  • If the device has a non-metallic casing, compact space, and moderate communication distance requirements (tens to one hundred meters), choose the EWM151-2G4T10S (on-board antenna) for the highest cost-effectiveness.

  • If the device has a metallic casing, limited installation space, or requires extreme communication distance (hundreds of meters), select the EWM151-2G4T10SX (IPEX antenna connector) and optimize RF performance by connecting an external antenna.

The EBYTE EWM151-2G4T10S series is not a simple improvement on traditional wireless modules but a groundbreaking innovation at the application level. It elevates wireless communication from "data transmission" to the level of "hardware interface extension", perfectly meeting the combined requirements for real-time performance, reliability, and ease of use in specific scenarios.

For developers who are constrained by wired connections or troubled by the complexity and latency of traditional wireless solutions, this solution provides an unprecedented, elegant, and efficient alternative to "wireless wires". Choosing the EWM151-2G4T series means not only choosing a module but also a more direct and faster way to implement wireless control.
