Did you route the current outputs to mcu opamp capable pins? #4

I noted you implemented the current sensors on each axis.

Did you route the current outputs to mcu opamp capable pins?

Hmmm.. no I didn't pay attention to it. The driver has current sense amps built-in, so the signal is already amplified and in the right range for the ADC via the external resistors (if my calculations are correct!). What would the op-amps be used for?

Thanks for highlight my comment on twitter.

Sounds fair enough to me, I didn't noted the built-in amplification block on the driver.

No worries, thanks for your interest. Would you be interested in testing the boards if we get a batch made?

@samuk , for sure, I also have m5 stack esp32 modules here and it would be great to write an initial microROS network using these modules being an initial skeleton of an mobile robot.
