Description

The EByte E73-2G4M08S1C module is a surface-mount solution built around the Nordic Semiconductor Semiconductor nRF52840 system-on-chip, engineered for demanding IoT edge nodes. Its ARM Cortex-M4F core with floating-point unit handles application logic and wireless stack processing efficiently, while the integrated 1 MB Flash provides ample space for firmware and device profiles.

Operating in the global 2.4 GHz ISM band, the module’s Bluetooth 5.0 radio supports advanced BLE features for robust, low-latency communication. The on-board ceramic antenna and optimized RF front-end ensure a reliable link up to 120 meters in open space, eliminating the need for external antenna components and simplifying PCB layout. The module’s industrial temperature rating (-40°C to +85°C) guarantees stable operation in harsh environments, from outdoor asset trackers to factory automation systems.

Key Features

  • High-Performance Core: ARM Cortex-M4F processor running at up to 64 MHz enables complex data processing and real-time control tasks.
  • Advanced Bluetooth 5.0: Supports 2x data speed (2 Mbps), extended advertising packets, and improved coexistence for reliable IoT network connectivity.
  • Integrated Memory: Combines 1 MB of Flash for application code and 256 KB of RAM for dynamic data, supporting feature-rich firmware.
  • Ultra-Low Power Design: Wide operating voltage range and multiple low-power modes (including system OFF) maximize battery life in portable and energy-harvesting applications.
  • Compact SMD Footprint: Measures just 13.0 x 18.0 mm with an on-board antenna, ideal for space-constrained PCB designs and mass production.
  • Industrial Robustness: Rated for operation from -40°C to +85°C, ensuring reliability in challenging environmental conditions.
  • Comprehensive Connectivity: Exposes SPI, UART, I2C, PWM, ADC, and GPIO interfaces for flexible sensor and actuator integration.

Applications

  • Wearable Electronics: Heart rate monitors, fitness trackers, and smartwatches requiring compact size and long battery life.
  • Smart Home Automation: Wireless sensors for temperature, humidity, occupancy, and smart lighting controls.
  • Industrial IoT (IIoT): Wireless data loggers, equipment monitoring sensors, and asset tracking tags in harsh environments.
  • Beacon & Proximity Solutions: Indoor location systems, point-of-interest information beacons, and asset management.
  • HMI & Remote Controls: Bluetooth-enabled handheld remotes, game controllers, and human-machine interface devices.

Frequently Asked Questions

How do I program the EByte E73-2G4M08S1C module?

The module is programmed using Nordic Semiconductor's nRF5 SDK or the Zephyr RTOS via a SWD (Serial Wire Debug) interface. You will need an external debug probe like a Segger or an nRF52840 DK to connect to the module's SWDIO and SWDCLK pins. Development can be done in Segger Embedded Studio, Arduino IDE (with core support), or PlatformIO. Firmware is typically written in C/C++ and flashed using the debugger.

What is the typical power consumption in advertising and connected states?

While exact figures depend on configuration, the nRF52840 SoC is designed for ultra-low power. In a typical BLE advertising scenario (1-second interval), average current can be in the tens of microamps. During an active connection with a 1-second connection interval, average current may range from a few hundred microamps to single-digit milliamps. Utilizing the chip's System OFF mode can reduce current to sub-microamp levels for maximum battery life.

Can I use an external antenna with this module?

No, the EByte E73-2G4M08S1C module features a fixed, integrated ceramic antenna and does not provide an external antenna connector like an IPEX or SMA. The RF layout is optimized for this internal antenna. For designs requiring an external antenna, you would need to select a different module variant from EByte's lineup that includes an antenna connector or design your own PCB with the nRF52840 chip directly.

What development tools and software are required to start a project?

You will need hardware like an nRF52840 Development Kit (DK) or a Segger Segger debugger to program the module via SWD. For software, install Nordic Semiconductor's nRF Connect SDK (which includes the nRF5 SDK and Zephyr RTOS) or the Arduino core for the nRF52. A serial terminal program is needed for UART debugging. Reference designs and pinout diagrams for the E73-2G4M08S1C are available from EByte to guide your schematic and PCB layout.
