Also, I forgot to add, I'm not very familiar with the Arduino type pcbs, can anyone suggest any button setups for the 3 buttons? I'll be using it in an upright Naomi driver cab so will have to create some sort of button setup. Any links or suggestions would be appreciated

Thanks for the response, it says version 1.3 on start up!

Hello all,
Apologies for the late late message, after a bout of illness and having my boards in storage, I'm finally getting round to getting my cabinet set up.
A couple of quick questions:
1. I received the board in 2019, so I'm guessing it would need the firmware updating to the latest version using the AVRDUDE software?
I intend to use mine with a RingEdge2 multi and ID 7 and 8, how do I get the new firmware?

2. I notice you mention dipswitch settings, are these for the same dipswitches on the back of the RingEdge that you also change for resolution settings etc?

If this works with Initial D 4 and 5 on the Lindbergh using the Darksoft Multi then I will definitely pick 1 up. 

I'm very interested in this, I have the Darksoft Multiboot on a Lindbergh so would love to have this solution working for ID4 and ID5. It's a bonus knowing it works with a Naomi multiboot setup as I have this also.
