Latest Electrical Technology Expert

We are proud that Beemong currently serves well-known importers, large STEM brands, large import retail giants, large training institutions, and government bidding projects in customer countries, and they have always maintained long-term and in-depth cooperation with us (95 % of our customers have continued to cooperate with us since their first order).

In 10 years of experience, we have had too many unforgettable stories with each of our customers. We have continued to work together on each order, and have also continued to enhance our relationship, slowly reaching a deep understanding.

Thanks to our customers’ absolute trust in us, our products have evolved from standard products from well-known brands such as Arduino, Raspberry Pi, Micro:bit, Makey Makey, etc. to gradually customized and personalized products. Product categories have also gradually expanded from DIY electronic products to CNC, 3D printing, drones, chips and other electronic products.

Looking back on the past, our winning advantage lies not in the lowest price, but in doing business in a down-to-earth manner and being a sincere person. We never deceive customers and sincerely cooperate with customers to solve every problem they encounter. We always adhere to one of the most important principles: allowing customers to find a real sense of security in cross-border procurement!

Description

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.
