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

The AT-09 is a compact module featuring a BLE chip, specifically the CC2540/CC2541. This module facilitates serial communication with the BLE chip using Rx and Tx pins. It bears a strong resemblance to the HM-10 module and is fully compatible with it. If you are familiar with the HM-10, transitioning to the AT-09 will be seamless.

This Bluetooth 4.0 TTL transceiver module, despite its small size, enables communication between your target device and iPhone/iPad (IOS 6 or above) or Android devices (Android 4.3 or above). It supports the configuration of slave or master roles, allowing users to set baud rates using AT commands.
