## Description

8-channel MIDI Trigger Board designed for controlling relays, lights, drums, solenoids, and other trigger-based devices from MIDI equipment.

This module converts MIDI note messages into eight independent trigger outputs corresponding to notes A–G (+1 any key). Ideal for interactive installations, DIY electronic instruments, lighting control, percussion triggering, and experimental MIDI projects.

Use a MIDI keyboard, sequencer, drum machine, or DAW to trigger external hardware directly. For example, control multiple spotlights from a MIDI controller keyboard or trigger external percussion circuits from a sequencer.

### Specifications:

- 8 × open-collector (ULN2803) trigger outputs, suitable for driving active-low relay boards, PLC inputs and logic interfaces.
- MIDI note-to-trigger conversion (Notes A–G)
- LED activity indicators
- Standard MIDI DIN input
- 5v JST Connector
- ATMEGA328 Microcontroller
- ULN2803G Darlington driver array

### Measurements:

- 46mm x 74mm x 23mm
- 4 x 2mm mount holes
