I just released a collection of #audio input and output modules for easy interfacing between #effect or #synth boards and the outside world (XLR and jack connectors). They are input buffers (for balanced line and hi-Z instrument such as electric guitar) and balanced line drivers.
Each board is made of 4 I/O units with a 25 mm pitch, sharing a symmetric power bus and can be cut at the desired length with a saw. Multiple boards can be daisy-chained.

Includes Gerber files for PCB manufacturing and #KiCAD source.
I may add more connectors or signal formats later, feel free to ask!
