The AccessibleMusic eurorack catalog provides accessible documentation for Eurorack synthesizer modules. Each entry provides:

ALM Busy Circuits

BlaknBlu

Divkid

Erica Synths

NOTE: All Erica synths pots have a very clear tactile line that you can use to help orient the pot. Also, to my knowledge so far, all of the black line of modules have keyed headers, making it easier to connect your modules.

Hermetic Modular

Thanks to Luke at Hermetic Modular for contributing these documents.

Make Noise

Make noise have written their own documentation. I haven’t been able to work as closely with them as I have with other companies, so your results may be different. For any issues with their individual documentation, please reach out to them directly via their support E-Mail. You’ll also note that there is one manual written here; this heavily inspired their documentation. Make Noise HTML Documentation

Moog

Nekyia Circuits

Noise Engineering

Noise Engineering is a group of amazing people who have put a lot of thought and effort into their documentation. The following link is not on this site, but is a page they will continue to maintain and update. They’ve very kindly and generously documented all of their modules.

Strymon

Tall Dog Electronics

WMD

Apart from being amazing to work with, WMD have also spent a lot of time and effort on creating cleaner versions of their docs, which are useful for everyone. Along with the module docs here, check out all of the WMD Manuals
