1. Product Overview
TYLC5 is a low-power embedded Wi-Fi module developed by Hangzhou Tuya Information
Technology Co., Ltd. It consists of a highly integrated wireless radio frequency chip, ESP8285,
and a few peripheral devices. It also has a built-in Wi-Fi network protocol stack and abundant

Regulatory Module Integration Instructions
2.2 List of applicable FCC rules
This device complies with part 15.247 of the FCC Rules.
2.3 Summarize the specific operational use conditions
This module can be used in household electrical appliances as well as lighting
equipments. The input voltage to the module should be nominally 3.0~3.6 VDC ,typical
User manual
value 3.3VDC and the ambient temperature o
This module using only one kind of antennas with maximum gain is 2.0 dBi .Other antenna
arrangement is not covered by this certification.
The antenna is not field replaceable. If the antenna needs to be changed, the certification
should be re-applied.
2.4 Limited module procedures
This module can be used in lighting equipment, smart frontpanel, household electrical
appliances. Normally host device should provide a power supply in range 3.0-3.6V,
typically 3.3V for this module. The limited module manufacturer will reviews detailed test
data or host designs prior to giving the host manufacturer approval.
f the module should not exceed 125℃.
2.5 Trace antenna designs
Not applicable
2.6 RF exposure considerations
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment .This equipment should be installed and operated with minimum distance
20cm between the radiator& your body. If the device built into a host as a portable usage,
TYLC5
the additional RF exposure evaluation may be required as specified by§ 2.1093.
2.7 Antennas
Module only contains one wire antenna. No additional external connectors.
2.8 Label and compliance information
The outside of final products that contains this module device must display a label
referring to the enclosed module. This exterior label can use wording such as: “Contains
Transmitter Module FCC ID: 2ANDL-TYLC5 ”,or “Contains FCC ID: 2ANDL-TYLC5 ”, Any
similar wording that expresses the same meaning may be used.
2.9 Information on test modes and additional testing requirements
User manual
a) The modular transmitter has been fully tested by the module grantee on the required
number of channels, modulation types, and modes, it should not be necessary for the
host installer to re-test all the available transmitter modes or settings. It is
recommended that the host product manufacturer, installing the modular transmitter,
perform some investigative measurements to confirm that the resulting composite
system does not exceed the spurious emissions limits or band edge limits (e.g., where a
different antenna may be causing additional emissions).
b) The testing should check for emissions that may occur due to the intermixing of
emissions with the other transmitters, digital circuitry, or due to physical properties of
the host product (enclosure). This investigation is especially important when integrating
multiple modular transmitters where the certification is based on testing each of them in
a stand-alone configuration. It is important to note that host product manufacturers
should not assume that because the modular transmitter is certified that they do not
TYLC5
have any responsibility for final product compliance.
c) If the investigation indicates a compliance concern the host product manufacturer is
obligated to mitigate the issue. Host products using a modular transmitter are subject to
all the applicable individual technical rules as well as to the general conditions of
operation in Sections 15.5, 15.15, and 15.29 to not cause interference. The operator of
the host product will be obligated to stop operating the device until the interference has
been corrected

2.10 Additional testing, Part 15 subpart B disclaimer
The final host / module combination need to be evaluated against the FCC Part 15B
User manual
criteria for unintentional radiators in order to be properly authorized for operation as a Part
15 digital device.
The host integrator installing this module into their product must ensure that the final
composite product complies with the FCC requirements by a technical assessment or
evaluation to the FCC rules, including the transmitter operation and should refer to
guidance in KDB 996369.
Frequency spectrum to be investigated
For host products with certified modular transmitter, the frequency range of investigation
of the composite system is specified by rule in Sections 15.33(a)(1) through (a)(3), or the
range applicable to the digital device, as shown in Section 15.33(b)(1), whichever is the
higher frequency range of investigation.

Operating the host product
When testing the host product, all the transmitters must be operating.The transmitters can
be enabled by using publicly-available drivers and turned on, so the transmitters are
active. In certain conditions it might be appropriate to use a technology-specific call box
(test set) where accessory devices or drivers are not available.
When testing for emissions from the unintentional radiator, the transmitter shall be placed
in the receive mode or idle mode, if possible. If receive mode only is not possible then, the
radio shall be passive (preferred) and/or active scanning. In these cases, this would need
User manual
to enable activity on the communication BUS (i.e., PCIe, SDIO, USB) to ensure the
unintentional radiator circuitry is enabled. Testing laboratories may need to add
attenuation or filters depending on the signal strength of any active beacons (if applicable)
from the enabled radio(s). See ANSI C63.4, ANSI C63.10 and ANSI C63.26 for further
general testing details.
The product under test is set into a link/association with a partnering WLAN device, as per
the normal intended use of the product. To ease testing, the product under test is set to
transmit at a high duty cycle, such as by sending a file or streaming some media content.
FCC Statement
Any Changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment. 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
