PCB layout for a simple MIDI (In-Through-Out) / UART - Adapter according to MIDI 1.0 Specification

PCB layout for a simple MIDI (In-Through-Out) / UART - Adapter according to MIDI 1.0 Specification

Does not directly include footprints for MIDI or TRS plugs but rather provides headers such as to more easily allow customization.

Also allows to use different voltage levels for RX, TX respectively (please use different resistors according to recommendations).
