Description <br> Kt6368a Bluetooth transparent module kt6368a is a dual-mode pure data chip that supports the functions of Bluetooth 51 ble and 21 spp. <br> And simple and clear transparent transmission and serial port at control functions. It greatly reduces the development difficulty and cost of embedded Bluetooth in other products. Kt6368a supports connecting mobile phones and two-way data interaction, commonly known as Bluetooth transparent transmission. <br> Through UART interface, it supports common at instructions, such as setting name, setting address, setting baud rate, etc <br> It is recommended that the voltage of 33V be 2.2v-3.4v. <br> The current at the moment of startup is 26ma. It is stable for about 1 second and to about 4mA * the UART cache given by the chip is 1K bytes, and the default baud rate is 115200 <br> <br> model : KT6368A <br> Colour:blue <br> Material:PCB <br> <br> Package Contents: <br> 1 x Bluetooth module <br> <br> Only the above package content, other products are not included. <br> Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. <br>
