FCC STATEMENT
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.
(2) This device must accept any interference received, including interference that may cause undesired
operation.
Any changes or modifications not expressly approved by the party responsible for compliance could void
the user’s authority to operate the equipment.
Please notice that if the FCC identification number is not visible when the module is installed inside an-
other 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: 2AHMR-ESP07S” any similar wording that expresses the same meaning may be used.
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This equipment should be installed and operated with a minimum distance of 20cmbetween the radiator &
your body. This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
The module is limited to OEM installation ONLY.
The OEM integrator is responsible for ensuring that the end-user has no manual instruction to remove or
install module.
The module is limited to installation in mobile application;
A separate approval is required for all other operating configurations, including portable configurations
with respect to Part 2.1093 and difference antenna configurations.
There is requirement that the grantee provide guidance to the host manufacturer for compliance with
Part 15B requirements.

Important European compliance information for module datasheets
This RF Solutions radio module meets the essential requirements of the European Radio Equipment
Directive 2014/53/EU and has been tested to European Harmonised Standards and CE marked where
space allows. A copy of the EU Declaration of Conformity can be located on the RF Solutions Website,
www.rfsolutions.co.uk/certification-i59.
When using the module in an end product, continued compliance can only be assured by incorporating the
module in accordance with RF Solutions specific installation instructions and in accordance with the
published information on the RF Solutions product data sheet. The antenna gain specification must be
adhered to at all times.
Article 3.1a and 3.1b of the EU Radio Equipment Directive 2014/53/EU should be assessed in the final
product.
Failure to follow this guidance may result in a non-compliant product being place on the European
Market, for which RF Solutions cannot accept any responsibility.
Further guidance may be obtained from RF Solutions Technical Support. Charges may apply to customer
specific product evaluation.

1. Preambles
ESP-07S WiFi module is developed by AI-Thinker Co.,Ltd, core processor ESP8266 in smaller sizes of
the module encapsulates Tensilica L106 integrates industry-leading ultra low power 32-bit MCU micro,
with the 16-bit short mode, clock speed support 80 MHz, 160 MHz, supports the RTOS, integrated Wi
-Fi MAC/BB/RF/PA/LNA, on-board antennas.
The module supports standard IEEE802.11 b/g/n agreement, complete TCP/IP protocol stack. Users
can use the add modules to an existing device networking, or building a separate network controller.
ESP8266 is high integration wireless SOCs, designed for space and power constrained mobile platform
designers. It provides unsurpassed ability to embed Wi-Fi capabilities within other systems, or to
function as a standalone application, with the lowest cost, and minimal space requirement.
Figure 1 ESP8266EX Functional Block Diagram
ESP8266EX offers a complete and self-contained Wi-Fi networking solution; it can be used to host the
application or to offload Wi-Fi networking functions from another application processor.
When ESP8266EX hosts the application, it boots up directly from an external flash. In has integrated
cache to improve the performance of the system in such applications.
Alternately, serving as a Wi-Fi adapter, wireless internet access can be added to any micro
Controller based design with simple connectivity (SPI/SDIO or I2C/UART interface).
ESP8266EX is among the most integrated WiFi chip in the industry; it integrates the antenna
switches, RF balun, power amplifier, low noise receive amplifier, filters, power management modules, it
requires minimal external circuitry, and the entire solution, including front-end module, is designed to
occupy minimal PCB area.
ESP8266EX also integrates an enhanced version of Tensilica’s L106 Diamond series 32-bit processor,
with on-chip SRAM, besides the Wi-Fi functionalities. ESP8266EX is often integrated with external
sensors and other application specific devices through its GPIOs; codes for such applications are
provided in examples in the SDK.
