Description

The CHAFON MU914 is engineered as a core component for automated identification systems, utilizing the ISO18000-6C (EPC Gen2) protocol for reliable tag communication. Its 33 dBm adjustable RF output allows operators to fine-tune the effective reading distance from 0 to 25 meters, adapting to diverse environmental conditions and tag densities. The module’s signal conditioning includes RSSI (Received Signal Strength Indicator) support, providing data to estimate tag proximity and optimize antenna placement.

Designed for seamless integration into fixed and mobile industrial applications, the MU914 operates efficiently from a 3.6V to 5.5V DC supply, with active power consumption under 1.5W. Its compact PCB footprint (67 x 54 x 7.9 mm) and 15-pin Molex connector facilitate installation in space-constrained enclosures. The provided cross-platform SDK support for C#, Java, Python, VB, and Delphi accelerates development for warehouse logistics, smart asset management, and automated laundry systems.

Key Features

  • Four independent SMA antenna ports for expansive area coverage and directional scanning setups.
  • Programmable RF output power (0–33 dBm) enables compliance with regional regulations and optimizes performance for specific tag types.
  • High-speed TTL UART (115200 bps) and SPI digital interfaces ensure rapid data transfer to host controllers.
  • Integrated RSSI functionality provides tag signal strength data for distance estimation and system diagnostics.
  • Ultra-low power management with active (<1.5W), standby (0.25W), and deep sleep (0.05W) modes maximizes energy efficiency in battery-powered applications.
  • Wide operating temperature range (-40°C to +65°C) ensures reliable performance in harsh industrial and outdoor environments.
  • Online firmware upgrade capability via UART allows for future feature enhancements and protocol updates.
  • Comprehensive SDK and library support for multiple programming languages simplifies custom application development.

Applications

  • High-speed warehouse inventory management and logistics tracking systems.
  • Industrial asset tracking for tools, pallets, and containers in manufacturing facilities.
  • Smart cabinet and library management for automated item check-in/check-out.
  • Laundry and textile management in commercial and healthcare environments.
  • Access control and personnel tracking in secure areas using UHF RFID badges.

Frequently Asked Questions

What is the operating voltage range for the CHAFON MU914 module?

The MU914 operates from a 3.6V to 5.5V DC power supply. This wide input range provides flexibility for integration with various power sources, including 5V USB supplies and regulated 3.3V embedded system rails, while ensuring stable RF performance.

What communication interfaces does the MU914 support for connecting to a host controller?

The module provides a primary TTL UART interface configured at 115200 baud by default and a secondary SPI interface. Both are 3.3V logic level, allowing direct connection to microcontrollers like Arduino, Raspberry Pi, and industrial PLCs for data exchange and command control.

How many antennas can be connected simultaneously, and what is the connector type?

The MU914 features four independent SMA female antenna ports. This allows for the connection of up to four UHF RFID antennas to create multi-point scanning zones, directional arrays, or to cover large areas, maximizing system coverage and read reliability.

Can the RF output power be adjusted, and what is the benefit?

Yes, the RF output power is software-adjustable from 0 to 33 dBm. This allows you to comply with regional RF emission regulations (e.g., ETSI in EU, FCC in US), minimize interference in dense reader environments, and optimize the read range for specific tag types and application scenarios.

What software development kits (SDKs) are available for this module?

CHAFON provides comprehensive cross-platform SDKs and libraries for several programming languages, including C#, Java, Python, VB, and Delphi. These SDKs include example code for basic inventory, multi-read, and GPIO control functions, significantly accelerating integration and custom application development.
