The HC-05 Bluetooth Module is a flexible UART-based wireless transceiver supporting both master and slave modes. Ideal for Arduino, ESP32, and other microcontroller-based systems, it operates at 3.3V logic, supports configurable baud rates, and provides reliable Bluetooth SPP (Serial Port Profile) communication for robotics, IoT, and home automation applications.
The HC-06 Bluetooth 2.0 Serial Module is a reliable, easy-to-use wireless transceiver that enables UART serial communication between your microcontroller (like Arduino or ESP32) and any Bluetooth-enabled device. Operates at 3.3V logic, supports master-slave role, and is ideal for wireless control, data logging, and automation projects.
The HM10-BLE Bluetooth 4.0 Module is a compact, low-power BLE (Bluetooth Low Energy) communication board based on the CC2540/CC2541 chipset, designed for serial wireless communication with Arduino, ESP32, and other microcontrollers. It supports AT commands, features low energy consumption, and enables transparent UART communication ideal for IoT, automation, and remote sensor projects.
