The 3-6V 400KV High Voltage Generator Boost Module converts a low 3V to 6V DC input into a high-voltage pulse output using an internal boost circuit. Its compact size and simple two-wire input make it suitable for high-voltage experiments, scientific demonstrations, ignition systems, and educational electronics projects. The module requires only a suitable DC power supply and switch for operation.

Warning: This module generates extremely high voltage and should only be handled by experienced users following appropriate electrical safety precautions.

Expand your microcontroller with 16 digital I/O pins through I2C using only SDA and SCL. Suitable for buttons, LEDs, relays and control circuits.

The UART MP3 Module with TF Card is a compact audio playback module based on the YX5300/JL MP3 chip, supporting MP3 and WAV files with 8kHz–48kHz sampling rates. It features a TF card slot and UART serial control, allowing Arduino, AVR, ARM, and PIC microcontrollers to control songs, volume, and playback modes. It is ideal for voice prompts, alarms, interactive projects, and embedded audio applications.

The JQ6500 Compatible MP3 Voice Player Module is a compact and economical audio playback module supporting MP3 and WMV formats. It provides UART serial control, TF card support, SPI Flash storage, and FAT16/FAT32 compatibility. Audio tracks can be selected and controlled using simple serial commands, making it easy to integrate with Arduino and other microcontrollers. It is ideal for voice prompts, announcements, alarms, interactive projects, and embedded audio applications.
