UHF RFID MODULE FAQS

What Makes the CK-M4L UHF RFID Module Ideal for High-Density Tag Environments?

The CK-M4L UHF RFID Module is engineered to excel in high-density RFID applications, such as inventory management, logistics, or retail. Key features include:

Multi-Tag Anti-Collision Algorithm: Enables simultaneous identification of 400+ tags per second, even in crowded environments.
Adjustable Output Power (1dBm steps): Optimize performance by tuning RF power from 33dBm (max) to avoid interference or extend coverage.
4-Channel Design: Deploy multiple antennas for 360° coverage or directional setups, ideal for conveyor belts or smart shelves.
Robust Protocol Support: Compliant with ISO 18000-6C/6B, EPC C1G2, and GB/T29768-2013, ensuring compatibility with global RFID standards.

This module’s dense-read capability and adaptive power control ensure reliable operation in warehouses, manufacturing lines, or retail stores with minimal setup.

How Does the CK-M4L UHF RFID Module Ensure Long-Range and Accurate Tag Operations?

The UHF RFID Module combines advanced RF engineering and precision tuning to deliver industry-leading read/write performance:

Extended Read Range: Achieve up to 10 meters for reading EPC tags (95% success rate) using an 8dBi circularly polarized antenna.
High-Sensitivity Receiver: Detects weak tag signals in noisy environments, enhancing accuracy.
Dual Modulation Modes (DSB-ASK/PR-ASK): Improves signal integrity for stable communication at varying distances.
RSSI Support: Measure tag signal strength to optimize antenna placement or troubleshoot coverage gaps.

For write operations, the module maintains a 4-meter range (90% success rate), suitable for asset tagging or IoT deployments.

Can the CK-M4L UHF RFID Module Integrate with Custom IoT or Embedded Systems?

Absolutely. Designed for seamless integration, the module offers:

Flexible Interfaces: A TTL serial port and USB 2.0 (DM/DP pins) for easy connectivity to microcontrollers, PLCs, or industrial PCs.
GPIO Customization: 5 programmable GPIO pins (3x GPO, 2x GPI) to trigger alarms, sensors, or LED indicators (e.g., integrate with infrared scanners via GPI).
Low-Power Design: Operates at 5V/4A with an 8W peak power draw, ideal for portable or battery-powered devices.
Firmware Upgradability: Future-proof your system by adding new protocols (e.g., RAIN RFID) or features via firmware updates.

The compact 85x80x8mm aluminum housing and wide temperature tolerance (-20°C to +70°C) make it suitable for harsh indoor/outdoor installations.
