DBM01 is a type of low energy data transmission Bluetooth module based on CC2540 from Texas Instruments. Combining the advantages of compact size, extra low power consumption, strong anti-interference and long communication distance, it is very suitable for short range wireless communication in Things of Internet. The module integrates PCB antenna on board. Because the RF circuits of DBM01 are well matched and optimized, users are free from time-consuming RF design and only need to focus on the slight work on UART communication.

DBM01 can be used to communicate with other Bluetooth devices such as iPhone system. This module can be switched between Central mode and peripheral mode by external I/O pin or AT commands. In peripheral mode, users can set modules in different power-saving modes by changing the broadcasting time through AT commands. DBM01 provides four types of matching modes for Central and Peripheral modules, which provides high flexibility for different applications.
