Are you in search of an HC-05 Bluetooth Module, a versatile and cost-effective solution for your wireless communication needs? Look no further. This Bluetooth module offers seamless wireless communication for a wide range of applications, from GPS navigation systems to water and electricity meter readings.
Whether you're an electronics enthusiast, a DIY hobbyist, or a professional looking for competitive pricing, this module is designed to meet your requirements. The HC-05 Bluetooth Module lets you switch between Master and Slave modes with ease using AT Commands, and it comes pre-configured in Slave Mode.
Its compatibility with devices such as phones, laptops, and microcontrollers ensures hassle-free connectivity. With a USART interface, it's a perfect fit for microcontrollers supporting USART communication. Plus, you can configure its settings effortlessly using the command mode.
Ideal for DIY projects and data exchange, this Bluetooth module provides LED feedback for seamless operation, giving you the best bang for your buck.
The HC-05 Bluetooth Module with Baseplate is a slave-only device. This means that it can connect to most phones and computers with Bluetooth but it cannot connect to another slave-only device such as keyboards and other HC-06 modules. To connect with other slave devices a master module would be necessary such as the HC-05 module, which can do both master and slave.

I bought this to make a small Arduino-based RC car. The HC-05 worked perfectly from the day I received it. It was easy to set up and connect via Bluetooth with my Arduino and phone. It hasn’t failed yet. I just love it!
I really like this product. It's working well, and I used it for my Bluetooth car. It's a nice product, and I'm enjoying it a lot.
The Bluetooth module is great. It takes a little time to connect, but once connected, it works very well.
These products work amazingly well in my Arduino Robot car. They're a must-have for anyone who's into robotics and Arduino.
I like this product. Products work superb in my Arduino Robot car. It's just as described, and I'm satisfied with it.
Good as per description and satisfied. Very nice packing and working well. I like this product. It's working, I used it for Bluetooth car
I used this product to use bluetooth to communicate between two Arduino boards. The product comes with simple instructions that make it easy to use. Robocraze are extremely professional, not only in their products, but in their packaging and care.

Hello, The HC-05 Bluetooth module provides a communication range of approximately less than 10 meters (about 33 feet). This makes it suitable for short to medium-range wireless applications. Keep in mind that the range may be slightly weaker indoors due to obstacles like walls.
