• Standard Bluetooth 2.0: Typically supports Bluetooth 2.0 or 3.0 for reliable communication.

• Range: Usually offers a communication range of up to 10 meters (depending on the module version).

• Pin Compatibility: Easy integration with microcontrollers like Arduino, Raspberry Pi, and other embedded systems.

• Low Power Consumption: Efficient for battery-powered applications.

• Master and Slave Modes: Can be configured to communicate as either a master or slave device.

• Secure Pairing: Uses simple pairing with other Bluetooth devices.

• Easy to Use: Comes with simple AT commands for setup and configuration.

The ZS040 Bluetooth Module is a more cost-effective, compatible version of the Bluetooth communication modules like the HC-05 or HC-06. This module is often used in DIY electronics and projects for wireless communication. It is designed to offer similar functionality to the original Bluetooth module but at a more affordable price point. The ZS040 is suitable for applications like remote control, wireless data communication, and sensor data transmission.

• Pinout Similarity: Has similar pinouts to other Bluetooth modules like the HC-05, making it easy to integrate into existing projects.

• Slave Mode Operation: Default configuration is typically for slave mode but can be reprogrammed for master mode.

• Range: Typically up to 10 meters, similar to other Bluetooth modules in its class.

• Easy to Interface: Comes with AT commands for easy configuration and communication setup.

• Cost-effective: A more affordable version of traditional Bluetooth modules for budget-conscious projects.

• Low Power Consumption: Designed for efficient power usage, ideal for battery-operated systems.

The HC-06 Bluetooth Module is a popular, affordable Bluetooth solution primarily used for serial communication between devices, such as microcontrollers (e.g., Arduino or Raspberry Pi) and Bluetooth-enabled devices like smartphones, tablets, or computers. It supports Bluetooth 2.0 communication and is generally used for creating wireless control systems, data transmission, and remote control applications. The HC-06 is usually a slave-only module (it cannot be configured to act as a master), making it ideal for projects where a single Bluetooth connection is needed.

Key Features:

• Bluetooth 2.0/3.0: Offers reliable Bluetooth communication for short-range wireless data exchange.

• Slave Mode: Operates only in slave mode (cannot be set as a master).

• Easy Integration: Designed to work with common microcontrollers like Arduino, ESP32, and Raspberry Pi.

• Serial Communication: Uses UART (Universal Asynchronous Receiver-Transmitter) for serial data transmission, making it simple to connect and use.

• Default Baud Rate: Typically operates at a baud rate of 9600 bps, but this can be adjusted via AT commands.

• Range: Offers a typical communication range of up to 10 meters (33 feet), depending on the environment and obstacles.

• Low Power Consumption: Consumes minimal power, making it suitable for battery-powered applications.

• Simple AT Commands: Can be easily configured and customized using AT commands via serial communication for pairing, baud rate setting, and other settings.

• Wide Application: Ideal for DIY projects, wireless data transmission, remote control systems, home automation, and more.

The ZS-040 Bluetooth Module is a cost-effective, HC-06 compatible version used for wireless communication between microcontrollers and Bluetooth-enabled devices like smartphones, tablets, or computers.
