AT-09 Bluetooth 4.0 Module (HM-10 compatible)

This AT-09 Bluetooth Module is a CC2541-based module with a dedicated breakout board that breaks out the pins and makes the module extremely easy to work with. It is an ultra-low-power and highly versatile unit that offers effective wireless Bluetooth Communications with Bluetooth 4.0 and BLE communication capabilities, making it a firm favorite amongst Makers worldwide.

Although the module itself is not extremely advanced, the versatile nature of the module and clever design of the breakout board enables it to be used for a wide range of projects and applications. As such, it can be used for home automation systems, wireless light switches or plug points, wireless signal transfers between devices, as well as many more ideas that are yet to be invented!

The AT-09 module operates on a low 3.3V input at the wireless frequency of 2.4GHz. It has a maximum efficient distance of around 60 meters and also features a number of security and privacy features to keep your projects safe from unauthorized access. And if that isn’t enough of a feature set for you, this module can also be used as a slave or master, meaning that it can either be utilized as the main controller for other devices or can be used to accept commands and react according to a larger control system.
