Access missing ADCs on DRV8301x-HC-C2- kit

Other Parts Discussed in Thread: CONTROLSUITE, TMDSCNCD28069ISO

I have to implement torque control using DRV 8301 HC-2 kit. However, from the schematics (1222.DRV830x-HC-C2-KIT_HWGuide), it seems that ADC A0, A4, A6 and B6 channels are not accessible. Are there external GPIO extender boards that can let me access these ADCs?

Hi Sourabh,

You may be able to find something by performing a search for "DIMM module extender" or by soldering a wire on the bottom of the existing DIMM connector.

Thanks Rick,

Is this the correct schematics for the Control Card?

Hi Sourabh,

I do not know. There should be some marking on the control card that identifies which model and revision you have.

If you cannot find the revision, please check with the C2000 forum.
