# DaemonBite SNES/NES USB Controller adapter with NTT Datapad support |
||||
## Introduction |
||||
With this simple to build adapter you can connect SNES and NES gamepads to a PC, Raspberry PI, MiSTer FPGA etc. The Arduino Pro Micro has very low lag when configured as a USB gamepad and it is plug n' play once it has been programmed. The controller type is auto-detected. |
||||
|
||||
The NTT Data Keypad controller for SNES is also supported in this version. For a faster version, use the project in the SNESControllersUSB folder. |
||||
|
||||
## Parts you need |
||||
- Arduino Pro Micro (ATMega32U4) |
||||
- Male end of SNES or NES controller extension cable |
||||
- Heat shrink tube (Ø ~20mm) |
||||
- Micro USB cable |
||||
