EC-LINK ECUHFA6 RFID Reader Module Instructions

ECUHFA6 RFID
Reader Module

Product Introduction

EC-UHF-A-6 is a six channel module that supports the 1ISO18000-6C/EPC C1G2 protocol. Users can communicate with their devices through the RS232-TTL pins on its interface.
Its wide power supply range (DC 3.6V~5.5V) and configurable GPIO interface can provide users with more choices. Due to its low power consumption and small size, the module is very suitable for embedding into handheld mobile devices and short distance applications, such as short distance handheld devices, embedded devices, card issuers, etc.

Product characteristics

• Support the IS018000-6C/EPC C1 G2 standard protocol ;
• The standby current is less than 10uA;
• Provide AIP, library functions, and demonstration kits;

Application scope

Applied to various wireless RFID application solutions such as handheld mobile devices, item and logistics management,warehouse management, animal management, item anti-counterfeiting, product traceability, electronic product monitoring and manufacturing and processing, production automation, etc.

Product size

EC-UHF-A-6 uses reference circuits and RF wiring

Reference circuit:

Rf wiring:
The EC-UHF-A-6 module provides an RF antenna pin for module and antenna connection. The RF track on the PCB connected to the module RF antenna pin should be a microstrip or other type of RF track with a characteristic impedance close to 50 ohms. The EC-UHF-A—6 module is equipped with a ground pin, located next to the antenna pin, to provide better grounding.
The characteristic impedance of the PCB wiring of ANT1~ANT6 should be controlled at 50 ohms, and the ground wire between them is not less than 1 mm. The impedance of the RF trace is usually determined by the width of the trace (W), the dielectric constant of the material, the height from the reference ground to the signal layer (H), and the distance between the RF trace and the ground (S). Microstrip or coplanar waveguides are commonly used in RF layouts to control characteristic impedance. The following are reference designs for microstrip or coplanar waveguides with different PCB structures:

Microstrip design on two layers:

Two designs of four-layer PCB coplanar waveguides

1. The third layer is the base ground, and the first layer is the RF cable
2. Thefourth layer is the base ground, and the first layer is the RF cableThe above information is for reference only, it is recommended to consult relevant materials or consult professionals for more information

Changes or modifications not expressly approved by the party responsible for compliance could void the user’ s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursua nt to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful inte rference in a residential installation. This equipment generates uses and can radiate radio frequency energy a nd, if not installed and used in accordance with the instructions, may cause harmful interference to radio com munications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turn ing the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receivingantenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
