1-Port UHF RFID Reader Module
RLM-1P 1-Port UHF RFID Reader Module
Embed one controlled UHF RFID read point inside your smart cabinet, compact terminal, or OEM embedded device.
Built for device teams that need to add one controlled UHF RFID read point into a compact enclosure before moving to pilot integration.
Why Use RLM-1P?
Why use RLM-1P for embedded RFID devices?
RLM-1P is designed for equipment that needs one controlled UHF RFID read point inside the device, rather than a separate external reader.
Control one RFID read point
Use one RF antenna port for smart cabinets, compact terminals, verification stations, and predictable item interaction points.
Simplify embedded integration
TTL host interface, 12-pin FPC connector, MMCX antenna connector, and compact dimensions support embedded device design.
Tune the read zone
Adjustable RF output and RSSI information help engineering teams validate antenna placement and read-zone behavior.
Support device development
SDK package, product datasheet, TTL communication notes, interface guidance, and antenna review are available by request.
Features
RLM-1P features for compact embedded RFID integration
1 RF antenna port
Designed for applications where one antenna position is enough to cover the required read zone.
TTL host interface
Supports embedded host controller communication through a TTL interface.
12-pin FPC connector
Provides compact host-side connection for device and cabinet integration.
MMCX antenna connector
Connects one external RFID antenna through a compact RF connector.
Adjustable RF output
RF output can be adjusted up to 33 dBm with 1 dB stepping.
Tag filtering and RSSI support
Tag data filtering and RSSI information support host-side RFID data processing.
Applications
Bring embedded RFID to smart cabinets, OEM devices, and verification stations
RLM-1P is best suited for compact devices with one defined RFID read zone and predictable item interaction.
Smart Cabinet Read Zone
Smart Cabinets & Tool Cabinets
One controlled RFID read point for item presence detection, access verification, consumable tracking, and small-zone inventory.
Best when one antenna position is enough
OEM Embedded RFID
OEM Embedded Devices
Add UHF RFID read/write capability into custom equipment using TTL host communication and one external RFID antenna.
Compact integration for custom equipment

Short answers about RLM-1P integration
Can RLM-1P be used inside a smart cabinet?
Yes. RLM-1P is suitable when one controlled antenna point is enough for item identification, presence detection, access verification, or small-zone inventory confirmation.
How do I know if one antenna port is enough?
One port is usually enough when the device has one clearly defined read area. If the project needs multiple shelves or independent zones, review multi-port modules.
What is a UHF RFID reader module used for?
A UHF RFID reader module adds RFID read/write capability into equipment, cabinets, terminals, and custom devices.
What host interface does RLM-1P use?
RLM-1P uses a TTL host interface through a 12-pin FPC connector.
What antenna connector does RLM-1P use?
RLM-1P uses an MMCX antenna connector for the RF port.
Can Raylink help review antenna placement?
Yes. Antenna placement is important for embedded RFID performance, especially inside cabinets, terminals, and compact equipment.
