Product Description:

Item	Description
Impinj R2000 Reading Module	◆ The RF module chip is designed based on Impinj R2000, a dedicated UHF chip with the highest performance.
High-performance multi-tags recognition algorithm	◆ The unique adaptive dynamic Q anti-collision algorithm V3.0 multi-tag recognition algorithm provides the highest recognition efficiency in the industry.
Optimization algorithm	◆ Specially optimized algorithm for reading a small number of tags ◆ Super fast speed for tags reading.
Dual CPU architecture design	◆ R2000 is responsible for polling tags, and CPU is responsible for data management. Polling tags and sending data are parallel, and does not occupy each other. Greatly improve the overall performance ◆ The CPU is responsible for generating real random numbers and for monitoring the running status of the system.
Fast 4-antenna polling function	◆ High-speed polling with 4 antennas. The shortest polling time for each antenna is about 50mS ◆ The polling time of each antenna can be configured separately.
Hardware monitoring	◆ Hardware monitors the running status of the CPU. ◆ 24 hours × 365 days of operation without crashing all year round.
RF power amplifier PA protection function	◆ The module integrates forward and reverse power detection functions. When the RF port of the module is not connected to the antenna, it can quickly detect the unconnected state of the antenna when the read power on, so as to protect the PA from being burnt out in open-circuit output.
PA high power output capability	◆ PA chip with stronger amplifying output ability, the maximum output power of the module up to 35dBm. The PA still keeps a linear state even the output is 33dBm. Higher output power with a longer tag reading distance. In specific applications, higher output power can activate weaker sensitivity tags.
Antenna connection detection function	◆ The module integrated antenna physical connection detection circuit can detect the antenna connection status of the module port quickly and accurately. ◆ The antenna connection status of all ports of the module can be read with one command.
Simple and efficient software and hardware interface	◆ Single power supply, without external tantalum capacitor, extremely simple peripheral circuit
Onboard temperature sensor	◆ The onboard high-precision temperature sensor can monitor accurately operating temperature of the system in real time.
Outstanding label reading performance	◆ The module with ultra-low receiving sensitivity and ultra-strong amplification output capability. More than 20 meters stable recognition distance of 9dBi circularly polarized antenna. More than 30 meters stable recognition distance of 12dBi circularly polarized antenna.
Simple and efficient command system	◆ Command system based on serial port. ◆ Concise, efficient, convenient and fast integration
Outstanding thermal design	◆ Effective heat-conducting structure. ◆ Large area of heat sink contact surface. ◆ The thermal coupling interface adopts thermal conductive silicone grease with high thermal conductivity, which does not volatilize at high temperature. ◆ Sheet metal aluminum shell body, long-term continuous work without over heat.

Application information:

1. Input power
We recommended to use at least two 220uF tantalum capacitors with a withstand voltage of 10V or more for the VCC port to reduce the traction of the power supply due to the rapid turn-on and turn-off of the power amplifier during radio frequency transmission. 0.1uF and 100pF capacitors filter out power supply ripple noise in different frequency bands respectively.

2. Pin
Built-in pull-up resistor to VCC, the module is powered on when high level or floating, and the module is powered off when low level (low level should be less than 0.3V, high level should be greater than 1.3V and less than VCC).

3. GPIO input and output
Input: Logic low＜0.56V, minimum 0V; Logic high＞1.66V, maximum 3.3V.
Output: Logic low＜0.99V, typical 0V; Logic high＞2.31V, maximum 3.3V;
The maximum output drive current of the IO port is 5mA.

4. Antenna connection
The output impedance of the antenna port is 50 ohms, and the antenna standing wave ratio is recommended to be less than 1.5. A better antenna standing wave ratio can achieve a better card reading effect.

5. Communication interface (RXD/TXD)
The communication interfaces RXD and TXD are both 3.3V TTL, and the default baud rate is 115200bps.
