Keyestudio LY51M02 Bluetooth-compatible 5.0 Module CC2640R2L chip for Arduino Compatible with iOS and Android

The Keyestudio LY51M02 is a low-energy Bluetooth 5.1 BLE data transmission module built around the reliable Texas Instruments CC2640R2L chip. It is an ideal wireless communication solution for Arduino makers, students, and developers building smart home devices, remote-controlled robotics, or data acquisition systems.

Low-energy Bluetooth 5.1 connectivity

Operating on the 2.4GHz ISM wireless band with GFSK modulation, this module utilises the Texas Instruments CC2640R2L chip to deliver efficient Bluetooth 5.1 BLE data transmission. It is fully compatible with both iOS and Android devices for seamless cross-platform integration.

Adjustable transmit power levels

The module features 13 adjustable power levels ranging from -21dBm to +5dBm, allowing you to optimise power consumption and signal range for your specific project. This makes it highly adaptable for battery-powered applications.

Versatile application possibilities

This module is highly suited for a wide range of projects, including smart home automation, intelligent lighting, wireless LED displays, and Bluetooth-controlled toys. It also integrates easily into industrial remote controls and data acquisition setups.

Simple UART communication interface

Featuring a standard UART communication interface with 3.3V TTL logic, the module operates on a flexible working voltage of 3.3V to 5V. With a low working current of just 4mA, it is highly efficient for continuous operation.

Compact design and integrated antenna

Measuring just 80x17x7mm, the module includes a built-in PCB on-board antenna and supports data rates of 5 to 10K/s. It is designed to work reliably in temperatures from 0 to 85 degrees Celsius and is supported by Arduino software wiki tutorials.
