JDY-10 CC2541 BLUETOOTH BLE V4 TTL MODULE
JDY-10 CC2541 Bluetooth BLE V4 module with TTL UART interface for wireless communication in Arduino, ARM, and IoT projects.
The JDY-10 CC2541 Bluetooth BLE V4 TTL Module is a compact, low-power Bluetooth Low Energy (BLE) module designed for wireless communication in embedded systems. Based on the Texas Instruments CC2541 chip, it supports Bluetooth 4.0 BLE standard and communicates via TTL serial interface (UART), making it easy to interface with Arduino, PIC, ARM, ESP32, and STM32 microcontrollers.
This module is ideal for IoT devices, smart home applications, wearable electronics, wireless sensors, and mobile app-controlled projects. With low power consumption, fast pairing, and reliable data transmission, the JDY-10 module provides an efficient solution for short-range wireless communication and remote control applications.
