Overview
A4091 3KLED is an open-source printed circuit board by A4091, from the A4091/a4091-collateral repository on GitHub. It is a 2-layer board of 22 × 11.7 mm with 3 parts on 3 nets, routed with 18 tracks and 0 vias.
README
README.mdA4091 collateral material
This repository contains all the artsy and non-PCB/non-logic/non-software pieces that went into making the ReAmiga 4091:
The Box
The original box dimensions are:
| Length | Width | Height |
|---|---|---|
| 43cm | 16cm | 6.5cm |
| 16.92" | 6.3" | 2.56" |
At least one DKB box out there was confirmed with these dimensions:
| Length | Width | Height |
|---|---|---|
| 39cm | 17cm | 5cm |
You can find the art work in the box/ subdirectory. NOTE: The first batch
of boxes we had manufactured were 17" x 6.75" x 3.25" as we did not have any
exact measurements to go by.

The Manual
The A4091 manual is 5.5" x 7.75" in size. If you get it professionally printed, it is recommended to use the English only version to keep costs down. If you are going to print all languages, you will probably need to choose Perfect bound instead of Stapled bound.
Recommended configuration:
- Size: W: 5.5" H: 7.75"
- Grayscale
- 80lb Satin paper
- 24+4 pages
- Binding: Staple
- Cover: 110lb Satin paper
- Cover: Color
- Cover: Soft Touch Lamination
Bracket
The metal bracket was designed by Szymon Gosk.
It is recommended to laser cut the bracket, but you will need the appropriate equipment to perform the narrow dual bend that prevents the metal from making contact with the connectors on the back of the card. Additionally it is recommended to apply some foil into the double bend.
Feel free to contact us if you need a bracket. We might still have some left.

Disk Labels
While the disk content is part of the a4091-software package, you can find a set of disk labels here.

Amiga 3000 LED adapter
A small adapter that lets you connect your A4091 to your A3000 LEDs. Gerbers and KiCAD files included.

Miscellaneous
There are a couple of 3d-printable designs available to accompany the A4091 SCSI controller.
-
An enclosure for the A4091 Terminator. This enclosure comes in two versions, Version v1 is optimized for printing on an FDM printer as the text on the lid is recessed. Version v2 has embossed text and is better printed on a Resin printer.

-
Szymon Gosk made a A4091 themed SCSI2SD adapter that you can 3d print yourself.

- There is also a newer version with a slightly different design that works well with ZuluSCSI too.

Questions
How big is the A4091 3KLED PCB?
It measures 22 × 11.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the A4091 3KLED use?
3 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the A4091 3KLED KiCad files?
From the A4091/a4091-collateral repository on GitHub, at the commit this page was made from: the board is a4091_3kled/A4091_3KLED.kicad_pcb and its schematic a4091_3kled/A4091_3KLED.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the A4091 3KLED design in my own project?
Its repository states no licence, so its author keeps all rights: ask A4091 before reusing the design.
