Full send 🤷‍♂️

I was planning on spending a bit more time researching and designing to also have the full featured PCB done but I got carried away and sent the FFB Enabler off to the fab to be printed and assembled. I haven't used an assembly service before so this is a new experience anyway.

Considering this design is untested and I may have ommitted a way to mount the PCB so when you plug it into the wheelbase, it'll be painful to remove... My current idea is to just hot glue a handle to the PCB, It'll work but it's a bit hacky and I forsee it failing faster than if I used a more positive attachment like a bolt.

Oh well, my main concern is the 5v regulator.

I've only added this circuit from the chips datasheet and their examples. In the case of the arduino nano the extra 3.3v line was already handled by the USB-UART adapater IC. Since this is a standalone ATmega and I need to program the chip using the ISCP lines anyway, that chip was omitted. There's every chance I've gotten somethig wrong and it doesn't even power up the ATMega. I've also never used an ATmega in this way, I've had a smaller project use an ATTiny85 but it's not overly sensitive to voltage fluctuations, doesn't need the 16mhz oscilator, ect.

Concerns aside, I'm excited to test this when it arrives. Untill then I'll be working on the full featured PCB and the housing it will go into. Along with the FFB Enabler I want to add an adapter ring. It's basically what I've already designed, just without the snout, so a custom wheel can be attached to a fanatec wheelbase for a lower cost than a full featured hub will be.
