Product Description
The AT-09 Right-Angle Version is a specialized Bluetooth Low Energy (BLE) 4.0 transceiver designed for high-density electronic assemblies and compact enclosures. Built on the industry-proven CC2541 chipset, this module provides full “HM-10” compatibility with a hardware twist: a factory-soldered 90-degree pin header.
This right-angle configuration allows the module to sit parallel to your main PCB or breadboard, significantly reducing the vertical height of your project. By removing the physical button and utilizing a streamlined baseboard, the AT-09 offers a “set-and-forget” wireless bridge that is perfect for permanent industrial installations, wearable tech, and sleek consumer electronics. Whether you are connecting to an iPhone (iOS) or an Android device, this module delivers ultra-low power consumption and stable transparent serial data transmission.
Key Features
- Space-Saving 90° Header: The right-angle pins allow for horizontal mounting, making it ideal for slim-profile cases and tight vertical clearances.
- Full iOS & Android Compatibility: Native Bluetooth 4.0 BLE support ensures seamless connectivity with modern mobile devices without the need for complex legacy pairing.
- Industrial CC2541 Core: High-stability chipset ensures consistent data throughput and low latency for critical monitoring applications.
- Button-Free Reliability: A streamlined design with no mechanical switches, eliminating potential points of failure and preventing accidental resets in vibrating environments.
- Dual-Voltage Logic (3.3V/5V): Integrated onboard voltage regulation and level shifting allow direct interfacing with Arduino, Raspberry Pi, and 5V industrial controllers.
- Transparent Data Mode: Functions as a “wireless serial cable”—data sent via UART is instantly available on the connected Bluetooth device.
