Product introduction
16-port module SIM7400E is a high-performance UHF 16-port RFID read-write module developed by the core Technology team based on IMPINJ’s 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 SIM7400 module provides eight SMA antenna interfaces and supports of 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.
In the High-speed 16 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, and more application 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.

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 traction 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 a low level
is connected or suspended, and the module is powered off when a high level is
connected (the high level should be greater than VCC-0.3V). 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 2 V Maximum 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 antenna is less than 1.5. A better standing wave
ratio of the antenna can get a better card reading effect.
The communication interface (RDX/TXD) Communication interfaces RDX and TXD are
TTL levels. The default baud rate is 115200bps

Peripheral Design Requirement
8.1 List of applicable FCC rules
FCC Part15 Subpart C, Section 15.247
FCC regulatory information
This device complies with Part 15 of the FCC Rules. Operation is subject to
the following two conditions: (1) this device may not cause harmful
interference, and (2) 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. End Device Labelling Please notice that if the FCC identification
number is not visible when the module is installed inside another device, then
the outside of the device into which the module is installed must also display
a label referring to the enclosed module. This exterior label can use wording
such as the following: “Contains FCC ID: 2AQ9M-SIM7300E” any similar wording
that expresses the same meaning may be used.
RF Exposure Compliance
This equipment complies with FCC radiation exposure limits set forth for an
uncontrolled environment. 8.2 Additional testing Part 15 Subpart B disclaimer
The grantee should include a statement that the modular transmitter is only
FCC authorized for the specific rule parts (i.e.FCC transmitter rules ) listed
on the grant and that the host product manufacturer is responsible for
compliance to any other FCC rules that apply to the host not covered by the
modular transmitter grant of certification.If the grantee markets their
product as being Part 15 Subpart B compliant( when it also contains
unintentional – radiator digital circuit y) then the grantee shall provide a
notice stating that the final host product still requires Part 15 Subpart B
compliance testing with the modular transmitter installed.
