  • Is there an input buffer or any voltage level/polarity protection built into this?

  • Interesting, may have to play with the clock as double that cps would be perfect for me. Ideally I'd hook up my own encoder that is a much higher CPR and can handle the RPM (optical disk and is rated for at least 5k RPM) as its already bolted to the motors I have, much simpler build for me than interfacing this 24 CPR encoder into the output drive.

    If you do run across a hard cps limit spec, I'd love to know. (another popular encoder project out there is limited to 150 cps according to their site) ;)

    Regarding the limits of this integrated encoder, I'd say any use with a motor is inadvisable. Generaly these are based on a contact pad wipe (like a turnpot) and will mechanically wear pretty fast at motor speeds and/or rotation counts.

  • Question about the max cps this can handle, I want to use an encoder to track the rotation speed of a motor (to keep two motors on separate drive and slightly unbalanced loads speed matched) and have some different re-purposed motors with 56/250/600 CPR encoders built in. While I could mount up a lower CPR encoder to the system output after all the pulley reduction and filter out any accidental velocity dither from the low cps that's more work and space. Nothing is going terribly fast, ~50RPM at the output max, but that's still in the 150kHz cps range using the lowest CPR motor encoders and I think it may be a bit fast for a board designed for fingers.

No public wish lists :(
