TYLC8 is a low-power embedded Wi-Fi module developed by Tuya. 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 library functions.
TYLC8 embeds a low-power 32-bit CPU, 1Mbyte of flash memory, 50KB of SRAM, and a wealth of peripheral resources.
As an RTOS platform, TYLC8 integrates all the function libraries of the Wi-Fi MAC and the TCP/IP protocol. Based on these function libraries, users can develop different embedded Wi-Fi products to meet their own needs.
TYLC8 has 2 lines of pins with a spacing of 2 mm.
The TYLC8 dimensions are 16.5±0.35 mm (W) x 11±0.35 mm (L) x 1.8±0.15 mm (H). The PCB thickness is 1 mm.

They are internal antennas soldered to the ANT pad of the module.
When an external antenna is soldered to the Wi-Fi module, to optimize the Wi-Fi performance, it is recommended that the distance between the antenna part and the other metal parts be at least 10 mm.
Note: The default dimensional tolerance is ±0.35 mm. If you have any other requirements on key dimensions, you can make them clear in the module datasheet after communication.
Set oven temperatures according to the following temperature curve of wave soldering. The peak temperature is 260°C±5°C.

FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this 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.
Note: This equipment has been tested and found to comply with the limits for a Class B digital 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 installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled rolled environment. This equipment should be installed and operated with a minimum distance of 20cm between the radiator and your body.
This radio module must not be installed to co-locate and operating simultaneously with other radios in the host system except in accordance with FCC multi-transmitter product procedures. Additional testing and equipment authorization may be required to operate simultaneously with other radios.
The availability of some specific channels and/or operational frequency bands are country dependent and are firmware programmed at the factory to match the intended destination. The firmware setting is not accessible by the end-user.
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. The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.
The end-user manual shall include all required regulatory information/warning as shown in this manual, including: This product must be installed and operated with a minimum distance of 20 cm between the radiator and user body.
The RF module is considered as a limited modular transmitter according to FCC rules. Even though the RF module gets an FCC ID, the host product manufacturer can not use the FCC ID on the final product directly. In these circumstances, the host product manufacturer integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining the FCC authorization by a Class II permissive change application or a new application.
