1 General Description
The AMW037 module from Zentri provides an ad-
vanced stand-alone Wi-Fi and networking solution.
An integrated module avoids difficult RF layout and ena-
bles designers to rapidly embed Wi-Fi and secure net-
working functionality into virtually any device.
The ZentriOS embedded connected operating system,
pre-programmed into all modules, may be used to fast-
track module integration into end-products.
With dimensions of just 16.5mm x 23.5mm and a wide
temperature range, the module is suitable for integra-
tion into most embedded applications.
The Wi-Fi device includes an integrated RF transmit
power amplifier and provides superior Wi-Fi perfor-
mance and full compatibility with all 2.4GHz 802.11b/g/n
Wi-Fi networks.
The AMW037 microcontroller core operates at a fre-
quency of 160MHz.
The AMW037 module offers extensive I/O and periph-
eral interfaces listed below, and provides
additional interface combinations by leveraging
multiplexing and alternate function capabilities.
1 x 4-Wire UART interface
8 x GPIOs
1 x 10-bit A/D converters
4 x PWM outputs
1 x ultra-low power wake input
The module is powered by a single 3.3V power supply.
Various powersave modes offer ultra-low power opera-
tion. Wake from low power sleep mode is possible using
IO pins or the internal real-time clock, and wake from ul-
tra-low power standby mode is achieved using the dedi-
cated wake pin.
The module has numerous modular approvals. See Sec-
tion 7, Regulatory Certification.

3.4 Digital IO Characteristics
All digital IO pads are bidirectional, non-inverting and tri-state. Each pad includes an input and an output buffer with
tristate control inputs. When the AMW037 is powered down, all output enable signals can be set to hold high or low
to minimize power consumption.
The hold functionality introduces some positive feedback into the pad. Hence, the external driver that drives the pad
must be stronger than the positive feedback. The required drive strength is however small in the range of 5uA.

6.4 Routing Recommendations
When designing a carrier board, the addition of ground fill directly underneath the AMW037 module, rather than signal
or power traces, is recommended. All ground pads adjacent to antenna pins must be connected to a solid ground
plane. Failure to comply with these recommendations may result in degraded performance of WLAN functionality.

6.6 Application Examples
Operation using ZentriOS
Each AMW037 module is pre-installed with and licensed to use ZentriOS-WL, Zentri’s feature-rich and reliable Wi-
Fi networking application. The module can be used with an external host microcontroller via the serial interface
command API.
To use ZentriOS-WL with a host processor, the module only requires an external connection to power and a UART
serial interface. A host processor connects to the UART (pins 10/11) as shown in Figure 8. Zentri recommends UART
hardware flow control (RTS/CTS) is used to improve the reliability of data communications. All required pull
up/down resistors are included inside the module.
For hardware design guidelines, see:
https://docs.zentri.com/hardware/zentri/amwx06/amwx06-hardware-design#pcb-layout
The general guidelines for the AMWx06 devices apply to all Zentri devices.

to integrate the AMW037 module into a finished product
without obtaining subsequent and separate FCC approv-
als for intentional radiation, provided no changes or
modifications are made to the module circuitry. Changes
or modifications could void the user’s authority to oper-
ate the equipment. The end user must comply with all of
the instructions provided by the Grantee which indicate
installation and/or operating conditions necessary for
compliance.
The finished product is required to comply with all appli-
cable FCC equipment authorization, regulations, require-
ments, and equipment functions not associated with the
transmitter module portion. For example, compliance
must be demonstrated to regulations for other transmit-
ter components within the host product; to require-
ments for unintentional radiators (Part 15 Sub-part B
“Unintentional Radiators”), such as digital devices, com-
puter peripherals, radio receivers, etc.; and to additional
authorization requirements for non-transmitter func-
tions on the transmitter module (i.e. Verification, or Dec-
laration of Conformity) (e.g., transmitter modules may
also contain digital logic functions) as appropriate.
Labeling and User Information
Requirements
The AMW037 module has been labelled with a unique
FCC ID number, and if the FCC ID is not visible when the
module is installed inside another device, then the out-
side of the finished product into which the module is in-
stalled must also display a label referring to the enclosed
module. This exterior label can use wording as follows:
If the exterior label area is smaller than the palm of the
hand, the end product user manual must contain the
above statement. The user manual should contain the
following additional statement:
Contains FCC ID: 2ABPY-5B9198
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 re-
ceived, including interference that may cause unde-
sired operation.

This module is intended for OEM integrators. The OEM
integrator is responsible for compliance in all the rules
that apply to the product into which this certified RF
module is integrated.
Additional testing and certification may be necessary
when multiple modules are used.
RF Exposure
All transmitters regulated by FCC must comply with RF
exposure requirements. OET Bulletin 65, Evaluating
Compliance with FCC Guidelines for Human Exposure to
Radio Frequency Electromagnetic Fields, provides assis-
tance in determining whether proposed or existing
transmitting facilities, operations or devices comply with
limits for human exposure to Radio Frequency (RF) fields
adopted by the Federal Communications Commission
(FCC). The bulletin offers guidelines and suggestions for
evaluating compliance.
If appropriate, compliance with exposure guidelines for
mobile and unlicensed devices can be accomplished by
the use of warning labels and by providing users with in-
formation concerning minimum separation distances
from transmitting structures and proper installation of
antennas.
The following statement must be included as a CAUTION
statement in manuals and OEM products to alert users
of FCC RF exposure compliance:
If the AMW037 module is used in a portable application
(i.e., the antenna is less than 20 cm from persons during
operation), the integrator is responsible for performing
Specific Absorption Rate (SAR) testing in accordance
with FCC rules 2.1091.
