WJ Communication’s WJM3000 UHF RFID module is designed to enable OEMs, System Integrators and VARs to offer RFID UHF Gen2 capability into new and existing short and long range applications such as printers, Mobile handheld and fixed readers. By leveraging WJ’s WJC200 Gen2 chipset, the WJM3000 enables cost effective, compact RFID-enabled devices. The WJM3000 extends industry leading features including Gen2 dense reader environment (DRE) . The WJM3000 reader module’s simple but powerful command set allows for fast creation of custom applications via an open-source DLL and API.
The WJM3000 can be set to transmit a range of output powers, providing increased flexibility to enable optimal for different near and far field applications. The module operates over the North American UHF frequency band (902-928 MHz) and includes the RF, digital circuitry and embedded firmware required for ISO18000- 6C (UHF Gen2) and ISO 180006B international standards. 3.3V CMOS level serial communications and 4 GPIO lines are available on a 15-pin connector. Mounting holes provide fast and easy mechanical integration. WJ’s free demo software offers quick evaluation of the module without software development.

Name
Description
Power Supply. +5.0V @ 1.3 A
Power Supply Ground Return No Connect Active High Power Enable. Grounding this pin shuts off entire module. Minimum logic high voltage is +2.5V. 5V tolerant. Low impedance driver or a pull up resistor less than 2K required. 3.3V CMOS logic-level UART transmit pin 5V tolerant CMOS logic-level UART receive pin 5V tolerant Active Low Reset Pin. 10K internal pull up, interface with open collector driver. When held low, WJM draws current but will not respond to commands. If nBL/ nPD is held low as nRESET is brought high, the WJM enters Bootloader mode. If nBL/ nPD is held high as nRESET is brought high, the WJM application starts. This pin can be left unconnected for minimal hardware configuration. A reset controller may be required if power supply rise time is slow. 5V tolerant Active Low Bootloader/PowerDown pin. 10K internal pull up, interface with open collector driver. This pin serves two functions. 1) If this pin is low at the rising edge of nRESET (including power-on), the Bootloader is activated for writing a new Firmware application (FW). If it is high, FW starts. 2) Once FW starts, bringing this pin low enables sleep mode. The module will not respond to API commands in sleep mode. Keep it high for normal operation. This pin can be left unconnected for minimal hardware configuration. 3.3V logic-level 3-state output: Logic high: OK Tri-State: Sleep Mode Logic low: Error Currently FW configures these pins as outputs, they display various debug and status signals to LEDs. If unused they can be left un-connected.
