Product Information
BT08-B Bluetooth module B Wireless serial port transparent transmission
Model Number：M2021025:BT08-B
Bt08-b Bluetooth module is designed for intelligent wireless data transmission and follows THE V3.0 Bluetooth specification. This module supports UART interface and SPP Bluetooth serial port protocol. It has the characteristics of low cost, small size and high sensitivity of sending and receiving. It only needs a few peripheral components to achieve large functions.
This module is mainly used in the field of short-distance data wireless transmission, which can be easily connected with the bluetooth device of the computer, avoiding tedious cable connection, and can directly replace the serial cable.

Bluetooth printer 16. Bluetooth remote control toy 17. Automobile diagnostic instrument OBDII
Tip
1. Bluetooth signals are greatly affected by surrounding obstacles, such as trees, metal, and walls, which can absorb or shield bluetooth signals to a certain extent. Therefore, it is not recommended to install bluetooth signals in metal shells. 2. Because the metal reduces the function of the antenna, it is recommended that the floor be not laid or cables be laid under the antenna of the module.
