Sadly it says it runs on 3.3V at 8 MHz. GIMX requires the atmega32u4 to run on 5V at 16MHz.

having trouble finding a local teensy 2.0 board....
Will this do the trick?

You can use most of Arduino Pro Micro clones on atmega32u4 as long as they work on 5V with 16 MHz

So I have wired this up using this board:

Have successfully flashed it.

The pins im using are 0 for D2 alterntive, and 1 as D3 alternative.
5v and GND

Not acting as it should. Get to "press PS button"
Pressing any of the RED buttons dont work, no inputs are read from G27.
Pressing PS on the DS4 works, D pad also works.

Thoughts?

Make sure you have EMUG29PS4 firmware if you want to use wheel and you bind your wheel to the config.

Yes that is the firmware i am using.
Also using the preconfigured pi image, which i believe comes with the g27 config setup?

EDIT: Think it is working... will do some testing and post photos.
Looks like this board works as a teensy alternative.

Update:
Finished my build, many thanks for the tutorial
Differences: I used an A-Star 32U4 Micro instead of the Teensy
Use Pin 0 for D2 alternative.
Use Pin 1 as D3 alternative.
5v and GND are the same.

To flash:
Install the Driver: https://www.pololu.com/file/0J1240/a-st ... .3.0.0.zip
Download the following and unzip into a folder: C:\arduino
http://download.savannah.gnu.org/releas ... -win32.zip
https://www.arduino.cc/download_handler ... indows.zip
atmega32u4.hex from GIMX FIrmware ZIP

Open CMD (Run as Admin)
Type in: cd c:\arduino
Type in (DONT PRESS ENTER): avrdude -p atmega32u4 -c avr109 -P COM4 -D -U flash:w:C:\arduino\atmega32u4.hex:i
Plug in board via USB, bridge the GND and RST 2 times in less than 1 second. LED will start pulsing. Press ENTER on CMD
Should see a Flash successful message if all went well.
