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 crea-
tion of custom applications via an open-source
DLL and API.
The WJM3000 can be set to transmit a range
of output powers, providing increased flexibil-
ity 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 18000-
6B 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 inte-
gration. WJ’s free demo software offers quick
evaluation of the module without software de-
velopment.

Description
Power Supply. +5.0V @ 1.3 A
Power Supply Ground Return

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 re-
quired 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 Boot-
loader 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.
