Re: CGS028 direction and reset questions

2016-04-13 by Ken Stone


- I noticed when the switch is set to UP, the direction jack is in fact outputting +10V. When looking at the schematic, it looks like it cannot be otherwise because it is directly connected to the +15v from the switch through a 47k and a 15k resistor... Am I missing something here ?


It's fine. It is a very low current. In reality, anything you plug into it will totally swamp it.

- some of the resistors marked 10k on the silkscreen (and the BOM) are 15k on the schematic (after UD, CLOCK and INH). What value should I use ? (I tried 15K instead of 10K on UD, but doesn't help)

Either will work. 15k were in the VER1.0 PCB.

Thanks. The chip looks fine, but no spare to try unfortunately...


I had 2 more questions maybe related to this :
