K5YBLEmesh Standard Module (PCB Antenna)
K5Y series of low-power Bluetooth module is a high-performance Bluetooth module which is
developed based on the Telink low-power Bluetooth SOC TLSR8250 chip. The module adopts the
stamp-type and side plug-in interfaces, is exquisite and compact, is fully lead out via ports and convenient
to use, and helps the users omit the complicated RF hardware design, development and production links.
Therefore, the users can easily realize the development of Bluetooth application programs on that basis,
shorten the R&D cycle, and seize the market opportunities. This model is a pure hardware module that
excludes any software. If you need the edition with software, please notify in advance.

interferences, and (2) this device must accept any interference received, including interference that may cause undesired operation.”
The user’s manual for the host product must clearly indicate the operating requirements and conditions that must be observed to ensure compliance
with current FCC / IC RF exposure guidelines.
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.
This Module is full modular approval, it is limited to OEM installation ONLY.
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.
The OEM integrator is responsible for ensuring that the end-user has no manual instruction to remove or install module.
The Grantee will provide guidance to the Host Manufacturer for compliance with the Part 15B requirements if requested.
- This device and its antenna(s) must not be co-located or operating in conjunction with any
other antenna or transmitter.
RF Exposure Information and 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. This transmitter must not be co-located or
operating in conjunction with any other antenna or transmitter
