This miniature module allows a Bluetooth® two-way data or audio transmission over a range of 20m.

This Bluetooth ® V2 module is certified in the "End Product" category, allowing clients who embed our solution to directly use the Bluetooth ® label.
The transmission and configuration of data is done via a UART serial interface TTL type. The gross throughput rate is 723Kbps . It is equipped with an integrated antenna or a uFL antenna connector.

The Audio version offers, in addition to these data functions, a SCO link that supports HFP, HSP, and AG (Audio Gateway).
