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

Overview of this 4.0 UART AT-09 Bluetooth Transceiver Module HM-10 Compatible

Introducing Roboway AT-09 Bluetooth 4.0 UART Transceiver Module at the best price in India with Roboway. This AT-09 is a small module that allows two devices to talk to each other wirelessly using Bluetooth 4.0, which is fast, reliable, and uses very little power. It is built around the CC2541 Bluetooth chip, which is known for its stability, low energy consumption, and strong signal range.

This module works just like the popular HM-10, meaning you can use the same AT commands and libraries that are available for HM-10 projects. It connects to microcontrollers like Arduino, ESP32, or STM32 using simple TX and RX pins, so sending and receiving data wirelessly is very straightforward. It provides a stable communication range (typically around 10 meters or more indoors), making it suitable for remote control, data logging, or sensor monitoring projects.

Features

Bluetooth 4.0 Technology – It works on Bluetooth Low Energy (BLE) which uses less power, making it ideal for battery-powered projects and devices.

HM-10 Compatible – Module fully compatible with the popular HM-10 module, so it can work with the same commands (AT commands) and example codes easily.

Low Power Consumption – It designed to consume very little energy, which helps in running projects for a long time on small batteries.

UART Interface – Communicates with microcontrollers like Arduino, ESP8266, or Raspberry Pi using simple serial (TX/RX) communication.

Small and Compact Size – The module is very small, making it easy to fit into portable projects, DIY gadgets, and embedded systems.
