# DaemonBite PC Engine / TurboGrafx-16 Controllers To USB Adapter

## Introduction
This is a simple to build adapter for connecting PC Engine / TurboGrafx-16 controllers to USB with turbo functionality support.

The input lag for this adapter is minimal (should be less 1ms average connected to MiSTer).

## Parts you need
- Arduino Pro Micro (ATMega32U4)
- Female connector end of controller extension cable or...
- Female DIN 8-pin and/or Female Mini-DIN 8-pin connector
- Micro USB cable
