Bluetooth module HC-05 TTL

Product detailed description

Allows the device to send and receive TTL data via Bluetooth interface.

The module's supply voltage can range from 3.3 to 5 V and is board stabilized for the circuitry. Input voltages higher than 7 V will destroy the module.

The input and output signal level is 3.2 V, when working with a microcontroller powered by 5 V, the levels need to be adjusted. The output signal can be taken from both the TxD and RxD pins, which allows communication with the module over a single wire, should this be necessary.

• 1pc Bluetooth module HC-05 - TTL

Notes:

• Input voltage 3.3~6V, PROHIBITED more than 7V! Caution - it does not have reverse polarity protection, make sure to connect it correctly. The "State" pin is the output for the status LED. If Bluetooth is not connected, the output flashes. If bluetooth is connected, the output is one.
• This product is not a standalone functional unit and may require professional installation.
