Specify dimensions of encoder board #10

Closed samuk closed 2 years ago

samuk commented 2 years ago

As discussed it makes sense to develop a small encoder board so that users can plug and play the encoders. It would be good if this encoder could be used in a variety of motors.

AS5048A-D

I suggest we stick broadly to the above dimensions, whilst noting that the BGM220 has 16mm spacing for the screw holes, so two 'notches' in the left and right of the above dimensions would give compatibility?

There would be a 7mm wide, side entry JST SHR-06-VS without flange specified for soldering to the SPI side. This would be positioned 'in reverse' with the cabling going over the encoder chip so that it could be used in a 2205

Here a picture and 3D render:

If we can work with these for the prototype, then I have bunch here. I can provide AS5048As or TLE5012Bs in this shape.

If we want a different shape, we'd have to have some made :-)

Great! nice one.. Would be good to get the PCB file, I'd like to get a quote from Makerfabs & this would be one of the components.
