Introduction
Thank you for purchasing a Halcyon keyboard! In this guide, you'll learn how to assemble and use your new keyboard.
This guide is relatively new, and may see changes and additions in the near future. If you have any questions or feedback, please don't hesitate to let us know!
In the box
You'll have purchased multiple parts, among them the keyboard kit itself, as well as case parts and other accessories.
In the main box (the one with Halcyon on it), you'll find the following items:
- A set of keyboard circuit boards;
- A Halcyon Quick Start Guide;
- A Halcyon Module Connection Kit, which contains:
- 3 x Flexible Flat Cables, 50mm, opposite side connectors (type B)
- 8 x M1.6 3mm screw
- 1 x 1.5mm Allen Key
Required tools
To assemble the keyboard, all you need is a small flathead screwdriver, which is used for the case. The kit already includes the Allen key you need to assemble a module, and any accessories that require a differently sized Allen key will also include one.
