Product introduction

8-port module SIM7300 is a high-performance UHF 8-port RFID read-write module developed by the core Technology team based on IMPINJ new-generation RF chip E710. It is designed to meet the requirements of new retail,  unmanned retail, RFID smart cabinet, RFID bookshelf and other applications that need to connect multiple antennas at the same time. The SIM7300 module provides eight SMA antenna interfaces and supports rf output up to 33dBm. It  can quickly read multiple labels and is the preferred choice for equipment in asset management, unmanned retail and new retail industries.

Product features

IMPINJ new generation E710 ULTRA high frequency radio reader chip, high sensitivity, wide reading range, low power consumption, strong performance.
Fast reading speed, stable reading, multi-label anti-collision ability, long reading distance, using 8dBi antenna, the reading distance is more than 12 meters, multi-label reading speed, up to 900 / second. High-speed 8 antenna polling  mode, the polling time of each antenna can be set separately, the 8 antennas can be set different RF output power, reading range is wider, more applicable scenarios.
Module support label RSSI detection, support antenna connection status detection, support working temperature detection, a variety of data detection is more convenient for users to use efficiently; The module can work stably in the  ambient temperature of -20℃ to +50℃, support stably in the ambient humidity of 5%-95%, efficient and stable performance, can be applied to a variety of harsh working environment.

Electrical characteristics

The current will vary depending on the load antenna.

The application of information

The input power
A tantalum capacitor of 100~470uF is recommended for the VCC port to be filtered to reduce the power tra ction caused by the rapid opening and closing of the power amplifier during RF transmission. The 0.1uF and 100pF capacitors filter out the power ripple in different frequency bands respectively.
Enable or reset
With built-in pull-down resistance, the module is powered on when low level is connected or suspended, an d the module is powered off when high level is connected (the high level should be greater than VCC-0.3 V).
NRST reset, built-in pull-up to 3.3V resistance, reset when low power.

GPIO interface
Input:
Logic low < 0.8V minimum 0V
Logic high > Maximum 2 V to 3.3 V
Output:
Logic Low maximum 0.4V
Logic High has a minimum of 2.9V and a maximum of 3.3V
The maximum output current of the I/o port is 5mA.
The antenna connection
The output impedance of the antenna port is 50 ohm, and the recommended standing wave ratio of the an
tenna is less than 1.5. Better standing wave ratio of the antenna can get better card reading effect.
Communication interface (RXD/TXD)
Communication interfaces RXD and TXD are TTL levels. The default baud rate is 115200bps

Peripheral Design Requirement

FCC STATEMENT
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
This device may not cause harmful interference, and This device must accept any interference received, including interference that may cause undesired operation.
Warning: Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a  residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is  no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is  encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

FCC Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20mm between the radiator & your body.

Integration instructions for host product manufacturers according to KDB 996369 D03 OEM Manual v01
2.2 List of applicable FCC rules
FCC Part 15 Subpart C 15.247 & 15.207 & 15.209
2.3 Specific operational use conditions
Operation Frequency:902.75~927.25MHz
Number of Channel:50 Channels
Modulation Type:ASK
Antenna Type:Polarized antenna
Antenna Gain(Peak):4.99 dBi (Provided by customer)
The module can be used for mobile or portable applications with a maximum 4.99dBi antenna. The host manufacturer installing this module into their product must ensure that the final composit product complies with the FCC requirements by a technical assessment or evaluation to the FCC rules, including the transmitter operaition. The host manufacturer has to be aware not to provide informationto the end user regarding how to install or remove this RF  module in the user’s manual of the end product which integrates this module. The end user manual shall include all required regulatory information/warning as show in this manual.
2.4 Limited module procedures
Not applicable. The module is a Single module and complies with the requirement of FCC Part 15.212.Because the module has shielding cover,it is a unrestricted module.
2.5Trace antenna designs
Not applicable. The module has its own antenna, and doesn’t need a host’s printed board microstrip trace antenna etc.
2.6RF exposure considerations
The module must be installed in the host equipment such that at least 20cm is maintained between the antenna and users’ body; and if RF exposure statement or module layout is changed, then the host 0product manufacturer required to take responsibility of the module through a change in FCC ID or new application. The FCC ID of the module cannot be used on the final product. In these circumstances, the host manufacturer will be responsible for re- evaluating the  end product (including the transmitter) and obtaining a separate FCC authorization.
