Wireless RF Modules and dongles for IoT | Coral RF

The N534EP is a feature-rich, programmable USB Sub-1 GHz radio dongle based on the advanced Texas Instruments CC1314 wireless microcontroller. Supporting key ISM bands from 169 MHz to 1200 MHz, it provides a versatile, low-power RF-to-USB bridge for IoT, smart metering, industrial automation, and long-range communication systems. Its integrated user button and status LED, combined with comprehensive development access, make it an ideal tool for both rapid prototyping and final product integration.

Key Features

Multi-Band Support: Available in variants for 433 MHz, 868/915 MHz, and 1200 MHz ISM bands.
User Interaction: Features a programmable button for user input (e.g., reset, mode switch) and a multi-color status LED for visual feedback on power, link, and data activity.
Onboard Programmability: The dongle supports in-system programming (ISP) via USB. Users can develop and flash custom firmware directly through the virtual COM port using a serial bootloader, enabling full application customization without a hardware debugger.
High-Performance Core: Powered by the TI CC1314 (CC1314R106T0RGZ), integrating an ARM Cortex-M4F and a dedicated RF core for efficient wireless processing.
Plug-and-Play USB: Enumerates as a standard CDC serial port, requiring no external drivers on modern operating systems.
Developer-Ready: LED I/O, buttom I/O and debug I/O pins are accessible via side headers for peripheral expansion and deep-level debugging.
Robust Design: 4-layer PCB with excellent RF layout for optimal impedance matching, interference immunity, and thermal performance.

Simple Selection Guide:

Choose the N537 Series (N537BP/N537EP) if you are building a unique, proprietary protocol and have the resources for full-stack development.
Choose the N537EP if your project requires standard protocols (like Wi-SUN or Wireless M-Bus) or your primary goal is to larger development time, cost, and risk.
