Here's an Oshpark link for now: https://oshpark.com/shared_projects/zTrcd4cp
Just an AS5047P chip and 0805 leds, capacitors, and resistor. The "incremental" led is nonfunctional so I'm leaving it off for now.
I have no more details to give... I'll see if I can get an oscilloscope on it soon.
Thanks! Can you give values for the caps and resistor?

Suggestions:
-Some of the vias are a bit close to pads and should be moved. I'm not sure if you auto routed this or not but the routing is not the best.
-Add some mounting holes to aid in stability for a 3d printed case.
-If it were me, I wouldn't break out all of the pins unless you need to.
-I'd also flip the solder points to be single side instead of thru-hole. Can then put it in a case and solder it without having to deal with both sides
-Make it square and/or panelize it. Round is the worst shape for per-inch pricing the way Oshpark does it.

Don't take any of those as complaints, these things are MFD.
