Description

The E73-2G4M04S1BX from EByte is a professional-grade Bluetooth Low Energy module engineered for reliable bidirectional wireless communication. Built around Nordic Semiconductor Semiconductor’s proven nRF52832 system-on-chip, it combines a powerful 32-bit ARM Cortex-M4F processor with floating-point unit and ample memory resources to run custom firmware stacks like Zephyr RTOS, Nordic Semiconductor’s nRF5 SDK, or Arduino core libraries.

Operating in the global 2.4GHz ISM band (2379-2496MHz), the module supports both legacy BLE 4.2 and modern BLE 5.0 feature sets, including 2x PHY for higher data rates and improved coexistence. Its integrated +4dBm RF power amplifier and -95dBm receiver sensitivity, coupled with the external IPEX antenna interface, provide robust link budgets for applications requiring extended range or penetration through obstacles.

Designed for surface-mount assembly, the module’s compact 17.5 x 23.5mm footprint and 1.8-3.6V wide voltage input make it a versatile drop-in solution for product designers, enabling rapid integration of Bluetooth connectivity into wearables, sensor nodes, remote controls, and smart home devices without complex RF layout challenges.

Key Features

  • Core powered by Nordic Semiconductor nRF52832-QFAA (QFN48) featuring 64MHz ARM Cortex-M4F with FPU.
  • Full compliance with Bluetooth Low Energy 5.0 and backward-compatible 4.2 specifications.
  • Integrated +4dBm transmit power amplifier and high-sensitivity receiver (-95dBm) for robust RF performance.
  • External IPEX (U.FL) antenna connector allows for antenna diversity, cable extensions, or higher-gain antennas.
  • Ultra-low power profile optimized for battery operation with configurable sleep modes and low active currents.
  • Industrial operating temperature range (-40°C to +85°C) and a 32MHz crystal oscillator ensure timing stability.
  • Comprehensive GPIO and peripheral interfaces (SPI, I2C, UART, PWM, ADC) accessible via the module's castellated pads.
  • SMD package design facilitates automated pick-and-place assembly for volume manufacturing.

Applications

  • Wearable health and fitness trackers, smartwatches, and medical monitoring devices.
  • Smart home automation sensors, beacons, and low-power remote controls.
  • Industrial IoT (IIoT) wireless sensor nodes for condition monitoring and telemetry.
  • Asset tracking tags and Bluetooth beacon systems for indoor positioning.
  • HID devices like wireless keyboards, mice, and game controllers.
  • Proximity sensing and secure pairing for consumer electronics.

Frequently Asked Questions

What development frameworks are supported for programming the E73-2G4M04S1BX module?

The module is fully programmable using Nordic Semiconductor's nRF5 SDK and nRF Connect SDK (Zephyr RTOS) for advanced BLE stack development. It is also compatible with the Arduino core for nRF52 via PlatformIO or the Arduino IDE with appropriate board support packages. Developers can write firmware in C/C++ to leverage all GPIOs, peripherals, and BLE profiles, with debugging supported via the SWD interface present on the module's castellated pads.

How do I connect an external antenna and what type is recommended?

The module features a standard IPEX (Generation 1, also called U.FL) female connector. You need a compatible IPEX-to-SMA pigtail cable or a directly attached IPEX antenna. For optimal performance, use a 2.4GHz antenna with 50-ohm impedance, such as a 2dBi or 5dBi whip antenna. Ensure the antenna is properly seated and the cable is not strained to maintain a reliable RF connection and prevent damage to the fragile connector.

What is the power consumption in different operating modes and how can I minimize it?

In active receiving mode, the module draws 4-6mA. Transmit current depends on output power, reaching up to ~10mA at +4dBm. For ultra-low power designs, utilize the nRF52832's built-in power management and put the core into System ON sleep mode (consuming microamps) while the radio is off. Implement connection intervals and advertising parameters wisely in your BLE firmware to maximize sleep time. A regulated 3.3V supply is typical, but the module can operate down to 1.8V for direct battery connection.

Can this module be used as a Bluetooth Mesh node?

Yes, the Nordic Semiconductor nRF52832 SoC at the heart of this module fully supports Bluetooth Mesh networking. You must implement the mesh stack using Nordic Semiconductor's nRF5 SDK for Mesh or the newer nRF Connect SDK. The module provides sufficient flash (512KB) and RAM (64KB) to run a mesh node application, including relay, friend, and low-power node features, enabling the creation of large-scale, multi-hop networks for lighting control or building automation.
