In addition to the Front Panel, Jack PCB, and Pico PCB (bought from Allen Synthesis or a third-party supplier), you will need the following components to complete your build. You will also need one 3.5mm cable (normal Eurorack patch cable) to perform the calibration process.
Please note that a few of these are multi-packs of components, and there may well be cheaper alternatives if you are doing a single build, so as long as the specification is the same you can get any of these components from any supplier most accessible to you.

The OLED has two suppliers listed, each with different pin configurations. The module supports either of these two configurations (the most common), but no others, so make sure that the one you buy, wherever you source it, has one of these two configurations.
