UHF RFID Module with Integrated Ceramic Antenna ID-UM01 (E310, UART)

The ID-UM01 is a UHF RFID reader module with its antenna built in: a 45.5 × 45.5 × 9.3 mm assembly carrying an E310 reader chip and a 2.5 dBi ceramic patch antenna, so your device needs no external antenna, coax or RF connector. It reads EPC Gen2 tags at a peak rate of over 350 tags per second and at over 4 m, depending on the tag and its surroundings, and takes commands over UART. It is sold from 1 unit (price on request); ask us for evaluation samples and SDK access.

What the ID-UM01 UHF RFID module with integrated antenna is for

It is made to be built into handheld terminals, desktop encoders, all-in-one readers, kiosks and portable devices for warehousing, logistics, production-line and inspection work. An anti-collision algorithm identifies moving or stationary tags, and carrier cancellation keeps it stable in electrically noisy places. It reports RSSI and phase per tag, inventories temperature-sensing tags and buffers up to 1,000 tags.

Designing around the built-in antenna

There is no antenna to source and no coax to route. A patch antenna reads mainly from its face, so keep that face behind plastic, clear of metal, batteries and displays, and route inter-board cabling close to ground and away from the antenna. The trade-off is reach: over 4 m suits a handheld, encoder or kiosk, while a dock door, a gate lane or several read zones need a reader with antenna ports.

Connectors, power and start-up

• 12-pin FFC/FPC (1.0 mm pitch): the full interface, with power, UART, enable, reset, and two inputs and two outputs at 3.3 V TTL.
• 5-pin harness (1.25 mm pitch, optional): power and UART only, for space-constrained designs.
• Supply: 3.6–5.25 V DC, sized for the 6.5 W peak (1.3 A at 5 V) at 33 dBm, with a 22–100 µF tantalum capacitor on VCC.
• Cooling: the module needs an external heat sink with air cooling; plan the enclosure for a draw of up to 6.5 W at 33 dBm (5 W at 30 dBm).
• Start-up: allow about 100 ms after power-up before sending commands, and don't assert RESET in that time. Drive EN high to run and low to power down to 0.25 mW; don't leave EN unconnected.
• UART speed: 9600–921600 bps (default 115200); use a higher rate for large tag populations.

Frequency band and regional profiles

The hardware covers 860–960 MHz, which includes India's 865–868 MHz band. One regional profile is active at a time, preset before dispatch or set by command; profiles include India, Europe, North America, Japan, Korea, Vietnam and China. Output is adjustable from 5 to 33 dBm in 1 dB steps, with 30 dBm the maximum on the regional builds for India, Europe, the US, Japan, Korea and Vietnam. Use EPC Gen2 tags tuned for the same band from the UHF RFID tags range.

SDKs and ordering

SDKs for Windows, Linux and Android, with C, C#/.NET and Java APIs, let one module serve a Windows encoder, a Linux kiosk or an Android handheld.
