In the era of rapid IoT and smart device proliferation, efficient and stable short-range wireless communication has become a core requirement for product intelligence. Leveraging its profound expertise in wireless communication, EBYTE  proudly introduces the EWM104-BT13 Series Bluetooth Proximity Switch Modules. It divided into the EWM104-BT13SP and EWM104-BT13SX, based on the PCB antenna interface and the third-generation IPEX antenna interface.These modules redefine Bluetooth-based proximity control with ultra-compact size, ultra-low power consumption, and simplified configuration, empowering applications in smart door locks, industrial control, consumer electronics, and beyond.

Product Overview of EWM104-BT13 Series

Core Advantages: Compact Size, Powerful Performance, Bluetooth 5.0 for Versatile Control

Based on Bluetooth 5.0, the EWM104-BT13 Series includes two models to meet diverse integration needs:

  • EWM104-BT13SP: Features a PCB onboard antenna, ideal for size-sensitive applications like smartwatches and miniature sensors.

  • EWM104-BT13SX: Equipped with an IPEX-3 antenna interface, supporting external high-gain antennas for complex electromagnetic environments or long-distance communication requirements.

Key highlights of the EWM104-BT13 Series:

  • Ultra-Compact & Low Power: Small form factor with 1.27mm stamp hole interface for easy integration; operates in the 2.4GHz band with adjustable transmit power (max. 11.5dBm), balancing communication range and energy efficiency to extend device battery life.

  • Simplified Configuration & Smart Reconnection: Supports universal AT commands for quick parameter setup and a dedicated WeChat mini-program for user-friendly configuration. Automatically reconnects after Bluetooth disconnection to ensure continuous stable communication.

  • Multifunctional Control & Status Monitoring: Offers 1 set of PWM complementary outputs and GPIO control, supporting "momentary/latching modes" for lock operations with configurable momentary trigger time. Built-in battery voltage detection provides real-time power level visibility on connected devices.

Application Scenarios

The EWM104-BT13 Series’ high compatibility and flexibility make it suitable for:

  • Smart Home: Smart door locks, drawer proximity sensors, and lighting control systems.

  • Consumer Electronics: Bluetooth anti-lost devices, wearable controllers, and wireless charging docks.

  • Industrial IoT: Automated production line sensors, equipment status monitoring, and low-power data acquisition nodes.
