From the project
MOD GRIP REPLACEMENT BOARD FOR SH-101 TRS MIDI IO
The project was designed in Kicad 6.0. The BOM and pos files for PCBA of the modulation grip spacer PCB with SMT spacers have been formatted for the JLC PCBA service.
You'll also need a Type A 3.5 MM TRS MIDI cable and a 2.5 MM TRS MIDI cable if you want access to MIDI OUT data. The 2.5 MM TRS to MIDI cable isn't as widely availabe, but is used by a lot of IK Multimedia iRig series products.

SH101 IO bill of materials (BOM)
3 components, 3 distinct parts — part numbers from the project's BOM.
