What I2C Expander is used On the Duex?
-
Judging from the previous discussion I had with @dc42 about adding fans and heaters to the expansion board I am developing, he implied that the exact I2C expander used would not force a firmware change. However since I do not want to mess with any firmware, I want to use the same exact parts and in the same config as used on the Duex where possible. My needs require it to be different in some areas. Thus, I am drawing heavily from opensource kicad model of the Duex 0.9a which is the latest duex open source documentation has been released on.
Unfortunately when I exported the BOM on the Duex, 5 kicad puked the below out, and I cannot find any pictures of the Duex detailed enough to read the chip:

@sphyloid thats an interesting kiCAD output you got there!
Have a look here:
https://duet3d.dozuki.com/Wiki/Adding_additional_output_ports
its the SX1509B -
@t3p3tony Thank you so much!

@t3p3tony said in What I2C Expander is used On the Duex?:
SX1509B
It was my spreadsheet viewer. For some reason it could not understand the formatting. Might have to buy excel, opening it with notepad shows that everything is there and correct

@sphyloid google docs imports those CSVs ok if you want a "free" alternative that's more than a text editor.
