AT-09 Bluetooth 4.0 Module CC2541 Compatible with HM-10

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 favourite amongst Makers throughout the world. 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 metres, and also features a number of security and privacy features to keep your projects safe from unauthorised 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 utilised as a main controller for other devices, or can be used to accept commands and react according to a larger control system.

The AT-09 is a module that contains a BLE chip (a CC2540/CC2541). This module allows performing serial communication with the BLE chip thanks to an Rx and a Tx pin. This module is also very similar to the HM-10 module and is also compatible with it. So if you have some experience with the latter, you will get started quickly with the AT-09.

Note: The Module can act as both Master and Slave.
