Missing resistor on DRV8825HW203_F PCB

[Alessandro]

Hi everyone,

I just noticed one of the pushbutton resistors R3 1.2K is missing from both schematic and PCB in revision 9 of DRV8825HW203_F.

Was it intentionally removed, and if so will the voltage divider still work?

Thanks
Alessandro

Its fixed, its now rev10 - and it was the DRV8825 board, not the DRV8825HW203 board
Thanks for finding the mistake

I'm having a really hard time trying to figure out which PCB to order from Aisler...
I intend to build a full controller with DRV8825.
What is the difference between:
https://aisler.net/brown_rb/my-project-repository/myfocuser-drv8825-hw203-mmtfbt
and
https://aisler.net/brown_rb/my-project-repository/myfocuser-drv8825-mmtfbt

Always go with HW203, the DRV8825 is the first designed board, was replaced with DRV8825HW203 early in the piece, the main difference is the the code is not the same and the MS0/MS1 lines are reversed.

As the PDF clearly states it is the DRV8825HW203 board which will continue to be supported and hence that is what is recommended multiple times in the PDF

Sorry, senile moment..., I was actually going for the DRV8825HW203 but seeing all boards were recently updated I got confused and was wondering what were the differences.
Thanks for your great work!!
