1. Product Overview
TYWE2L is a low power-consuming built-in Wi-Fi module developed by Hangzhou
Tuya Information Technology Co., Ltd. It consists of a highly integrated wireless radio chip
(ESP8285) and several peripherals, with a built-in Wi-Fi network protocol stack and robust
librar y functions. TYWE 2L also provides a low power-consuming 32-bit CPU, 1 MB flash, 50
KB SRAM, and various peripheral resources. TYWE2L is an RTOS platform that integrates all
the function libraries of the Wi-Fi MAC and TCP/IP protocols. Users can develop
embedded Wi-Fi products as required based on the function libraries.

conditions: (1) This device may not cause harmful interference. (2) This device must accept any
interference received, includi ng interferen ce that may cause undesired operation.
15.21
Note: The grantee is not responsible for any changes or modifications not expressly approved by
the party responsible for compliance. Such modifications could void the user’s authority to
operate the equipment.
15.105(b)
NOTE: This equipm ent has b een tes ted and fo und to com ply wi th the lim its for a Class B d igital
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
杭州涂鸦信息技术 Version1.0.2

installation. If this equipment does cause harmful interference to radio or television reception,
which can be determ ined b y tu rning t he equipm ent off a nd on, the user i s encouraged to t ry to
correct the interference by o ne or more of the following measures:
• Reorient or relo cate 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.
The final host / module combination may also need to be evaluated against the FCC Part 15B
criteria for unintentional radiators in order to be properly authorized for operation as a Part 15
digital device.
The user’s manual or instruction manual for an intentional or unintentional radiator shall caution
the user that changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment. In cases where the manual
is provided only in a form other than paper, such as on a computer disk or over the Internet, the
information required by this section may be included in the manual in that alternative form,
provided the user can reasonably be expected to have the capability to access information in that
form. Any modifications made to the module will void the Grant of Certification, this module is
limited to OEM installation only and must not be sold to end-users, end-user has no manual
instructions to remove or install the device, only software or operating procedure shall be placed
in the end-user operating manual of final products.
RF 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 of 20 cm
between the radiator and your body.
