Product Description
The AT-09 is a high-efficiency Bluetooth Low Energy (BLE) 4.0 module designed for ultra-low power consumption and seamless integration with modern mobile ecosystems. Based on the industry-standard CC2541 chipset, it serves as a cost-effective, high-performance alternative to the HM-10 module.
Unlike older Bluetooth 2.0 modules (like the HC-05/06), the AT-09 is specifically engineered for iOS and Android compatibility, making it the go-to choice for app-based hardware control. This specific version features an integrated physical button and level-shifting circuitry, allowing users to easily reset or enter configuration modes without complex wiring. It is the perfect bridge for developers and businesses looking to add “Smart” connectivity to battery-operated devices, wearable tech, and remote sensors.
Key Features
- iOS & Android Universal Compatibility: Supports Bluetooth 4.0 BLE, allowing direct connection to iPhones and modern Android devices without complex pairing codes.
- Ultra-Low Power Consumption: Optimized for battery-sensitive applications, with a deep-sleep mode drawing micro-amps.
- Integrated Level Conversion: Safe for use with both 3.3V and 5V microcontrollers (Arduino, Raspberry Pi, ESP32) thanks to onboard logic-level shifting.
- Onboard Configuration Button: Features a physical “State/Reset” button for easier AT command entry and factory resetting.
- High Performance: Features an onboard PCB antenna for stable data transmission and a high-speed CC2541 core.
- Compact 6-Pin Interface: Standard header pins (State, VCC, GND, TXD, RXD, BRK) for easy breadboard or PCB integration.
