Built around the JADAK M7E Hecto module, it works with standard EPCglobal Gen 2 passive UHF tags.The board can read many tags at once, making it useful for logistics, asset tracking, race timing and access control projects where tap-to-read low-frequency RFID is not enough. Output power is adjustable so you can tune the read range to suit your environment.For quick testing, the integrated PCB trace antenna provides a short-range option straight out of the box. For longer range, connect an external antenna to the U.FL connector. You can talk to the board over USB-C via the onboard CH340C converter, or use the broken-out serial pins on the 0.1" header for microcontroller projects.SparkFun provides supporting documentation including schematic, Eagle files, board dimensions, hookup guide, M7E Hecto user guide, RFID guides, an Arduino library and a GitHub hardware repository.Features:UHF RAIN RFID: Built around the M7E Hecto UHF RAIN® RFID Reader.Tag support: Reads and writes standard EPCglobal Gen 2 tags.Simultaneous reading: Can scan multiple tags simultaneously.Read performance: Achieves up to 300 tags per second.Write performance: Typical write time of 80 milliseconds for standard 96-bit EPC tags.Adjustable power: Power output is adjustable from 0dBm to 27dBm.Onboard antenna: Built-in PCB trace antenna provides a read range of roughly one to two feet.External antenna: U.FL connector supports an external antenna, sold separately, for read distances of up to 16 feet (4.9 meters).Plug-and-Play USB: Built-in USB-C connector via a CH340C converter allows direct connection to a computer with no soldering required.Embedded Serial: Serial lines are broken out to a standard 0.1" header.Easy Switching: 2-way switch toggles between the USB interface and the hardware serial pins.Current protection: Internal current limiting circuit.Thermal protection: Built-in thermal-management.GPIO access: Enable & GPIO PTH Pins.Specifications:RFID reader: M7E Hecto UHF RAIN® RFID ReaderProtocol: EPCglobal Gen 2 (ISO 18000-6C) with nominal backscatter rate of 250kbpsRead and write power levels: Separate read and write power levels, command adjustable from 0dBm to 27dBm in 0.01 dB stepsRead rate: Up to 300 tags/sec to read 96-bit EPCWrite time: 80msec typical for standard write of 96-bit EPCSupply Voltage: 3.3V-5VSupply Current: 1A MaxCurrent limiting: Internal current limiting circuitFull power mode consumption (@5V): 0.665WMinsave power mode consumption (@5V): 0.140WSleep power mode consumption (@5V): 0.080WOperating Temperature Range: -40°C to 60°CThermal management: Built-in thermal-managementSerial interface: USB-C ConnectorSerial interface: 0.1"-Spaced PTH Header (3.3V logic)Serial interface selection: 2-way Switch for Serial Interface SelectionPTH pins: Enable & GPIO PTH PinsAntenna option: Integrated PCB Trace Antenna (Default)Antenna option: U.FL Connector for External Antenna ConnectionOnboard antenna read range: roughly one to two feetExternal antenna read distance: up to 16 feet (4.9 meters)RF exposure warning: Ensure personnel do not stand in the antenna's radiation beam unless they are more than 21cm from the antenna's face (to comply with FCC limits for long-term exposure).A good fit for makers and engineers building UHF RFID projects that need fast tag reads, adjustable range and a choice of USB-C or embedded serial control. **Product Type:** RFID Reader ## Images -
