MP3 Player Module is an audio playback device capable of reading and playing common audio file formats, such as MP3 and WAV, directly from a microSD card. It can be controlled by a microcontroller to play, pause, or skip tracks, making it ideal for audio-based projects, such as alarms, voice prompts, or interactive systems.
GPS stands for Global Positioning System, a satellite-based navigation technology that provides positional, navigational, and timing data. By receiving signals from multiple satellites, a GPS module can calculate the user’s 3-dimensional position—specifically, latitude, longitude, and altitude. This makes it essential for applications involving tracking, mapping, and location-based services.
Wi-Fi is an acronym for Wireless Fidelity, a technology that enables wireless connectivity for internet-based applications, such as those in the Internet of Things (IoT) ecosystem. It allows devices to communicate and exchange data over local networks or the internet without physical connections.
BLE, short for Bluetooth Low Energy, also known as Bluetooth 4.0, is a wireless communication technology designed for low power consumption while maintaining reliable data transmission. Unlike Classic Bluetooth, BLE is optimized for applications that require long battery life, making it ideal for wearables, sensors, and battery-powered IoT devices.
Bluetooth Module enables a microcontroller to communicate wirelessly with other Bluetooth-enabled devices using Bluetooth communication. It interfaces with the microcontroller through the Serial UART communication protocol, allowing for bidirectional data transmission—both sending and receiving data are managed by the Bluetooth module itself.
