Short Description
The Nextion MIDI I/O Interface is a professional TTL serial-to-MIDI converter module designed for Nextion HMI displays and other microcontrollers with UART communication.
It enables seamless MIDI IN and MIDI OUT connectivity through standard 5-pin DIN ports, allowing Nextion displays to function as standalone MIDI controllers, receivers, or interfaces in audio and music control applications.
Featuring optimized drivers, EMI filtering, and isolated MIDI input circuitry, it ensures reliable communication even with long MIDI cables and in electrically noisy studio or stage environments.
The onboard mode switch allows users to toggle between MIDI communication mode and programming pass-through mode for convenient device programming and debugging.
