Module IntroductionModule parameters

EH-MC30 Bluetooth® low energy single mode module is a single mode device targeted for low power sensors and accessories.

The module offers all Bluetooth® low energy features V4.2: radio, stack, profiles and application space for customer applications, internal integration Cortex-M0 CPU so no external processor is needed.

The module also provides flexible hardware interfaces to connect sensors, simple user interfaces or even displays directly to the module.

The module can be powered directly with a standard 3V coin cell batteries or pair of AAA batteries. In lowest power sleep mode it consumes only 2.6uA and will wake up in few hundred microseconds.

After buying Bluetooth® module, we provide free technical support APP of iOS or Android.
