AT-09 Bluetooth 4.0 UART Transceiver Module
AT-09 Bluetooth 4.0 BLE UART transceiver module with low power consumption—ideal for Arduino, IoT, and wireless sensor projects.
Description
The AT-09 Bluetooth 4.0 UART Transceiver Module is a compact Bluetooth Low Energy (BLE) communication module designed for low-power wireless data transmission. Based on the CC2541 chipset, it supports Bluetooth 4.0 BLE protocol, making it ideal for battery-powered and IoT applications.
The module communicates via a UART (TTL) serial interface, allowing easy integration with Arduino, ESP32, STM32, Raspberry Pi, and other microcontroller platforms. Its low energy consumption and small form factor make it suitable for wireless sensors, wearable devices, home automation, and BLE-based mobile applications.
The AT-09 supports configuration through AT commands, enabling flexible setup for connection parameters, baud rate, and device roles. It provides stable and reliable BLE communication for short-range wireless projects.
