Topic: Anyone have an Adafruit Wave Shield? I need a few measurements taken. (Read 1 time) previous topic - next topic

Specifically, I need to know, to a fair level of precision (1/32" would be ideal):

1. The diameter of the thumbwheel.
2. The thickness of the thumbwheel.
3. The distance from the face of the PCB to the underside of the thumbwheel.
(The distance from the face of the PCB to to the center of the edge would be good as well.)

I've already looked at the datasheet for the part, but it doesn't show the size of the wheel itself and I need to know that so I can size and position a cutout for it in a panel.

I have a few (and a custom hybrid version as well)..

however I am at work.. and will have to wait until I am home...(if that works for you?)

I'll use my digital calipers.. (as accurate as that can get at least)

Sure that would be great.  Otherwise I'll have to wait a week for parts to arrive to do what I need to do.

1.   25.04mm / 0.985 in
2.   2.42mm / 0.095 in
3.   6.83mm / 0.268 in
4.   8.23mm / 0.324 in

Keeping in mind that I've noticed that some of the thumbwheels are not mounted perfectly level to the PCB...

Thanks a bunch, I hadn't been able to get to ordering that part yet, so these measurements will be a big help.

I'm actually designing a board that uses that thumbwheel, so I can make sure they're all soldered flush with the pcb.
