# DaemonBite Saturn Controller To USB Adapter
|
|
## Introduction
|
|
This is a simple to build adapter for connecting SEGA Saturn controllers to USB. Currently it supports normal digital Saturn controllers, 3D controllers are not supported.
|
|
|
|
The input lag for this adapter is minimal (about 0.75ms average connected to MiSTer).
|
|
|
|
## Parts you need
|
|
- Arduino Pro Micro (ATMega32U4)
|
|
- Male end of a Saturn controller extension cable
|
|
- Heat shrink tube (Ø ~20mm)
|
|
- Micro USB cable
|
|
|

## How to assemble (please ignore the switch)
|
|
Check the SegaControllerUSB readme for an idea how to assemble.
|
|
|
|
## Retro Bit 2.4GHz wireless controller
|
|
The Retro Bit 2.4GHz wireless controller is officially not supported but you can enable support for it in the code (with a huge increase in lag as a side effect).The receiver of the Retro Bit 2.4GHz controller needs to be plugged in after the adapter has been connected to USB and the RETROBIT define needs to be uncommented.
