LSD4BT-K5y 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. Product Characteristics Working Frequency Band
