Saying its useless is simply not correct. Cheapest option to get rid of it? No, but for sure on of the nicer
even if I'm a skeptical, I admit the Wyrd made a big difference in my setup cause apparently my PC USB sucks (could be overpopulated? no idea...? also in a tiny ITX PC case).
not sure how it would apply to mice and such but... I could try it I suppose!
it also makes a huge difference which DAC you use since you have different power supply circuitry in different DACs. some don't have a lot of interference/noise filtering at all, and some basically do the same thing as the Wyrd except built-in.

Yes, look at the test I posted you. It doesn't even do that.

Can someone tell me which sensor is on the Bloody V4M with certainty?

https://www.bloody.com/en/product.php?pid=10&id=105

I would guess it is the 3050, but would like a answer from someone who knows to confirm it.

definitely not a 3050 man..

3200 cpi / 30g is picture perfect paw3305
3050 is 2000cpi / 20g

75ips is closer to the declared 68 of the 3305
and they luckily posted the MP/s which is 1024*3600=3686400 (3.68 MP/s, they forgot the period)
the sensor array on the 3305 is 32*32 and frame-rate is 3600.

You're welcome.

****, thanks. I was still open to 3050 if absolutely necessary, but sensors like 3305/3309/3325/3330 just skip for my usage. 3325/3330 are supposed to be better than 3050 from what I know, but 3050 just deals better with my low sens.

datasheet stuff on pixart site seems to be gone, can't find anything about the 3325.

since the 3325 is apparently super similar to a 3090, does it have native steps? is any step of 50 or 100 (or whatever it can do) fine? I'm also assuming the lower the cpi the higher the malfunction speed, right?

EDIT: ok so page with datasheet stuff was just moved, but still can't find anything :^( assuming it doesn't have native steps like more modern stuff at this point I think, but big shrug emoji

Apparently they are not similar at all.

They removed most of the older stuff, which is just awful. And the newer ones are not thorough like their predecessors, so no useful info for your question even with the sheet.
I downloaded as many as I could find from wayback and other sources.

Oh does anybody have a working link or an offline copy of the 3090 srom 6b (6x ?) datasheet?

Why do you say the 332x is similar to the 3090/80/60 ? The 332x series is derived from the am010 which is a newer architecture, 8 pin DIP (opposed to 20 pin), had relatively low framerate/ips and used weird 83.333... cpi native steps.
Hope they re-worked the coding.

pretty sure I read in the past that am010 was similar to 3090, but shame on me for not looking more into it before assuming that was actually right. Thank you

also I'm guessing it isn't at all this simple because of the different operating voltage (and maybe more), but would it be possible to solder in a 3327 where a 3325 would normally be on a board since they're both 8 pin and require the same lens? it's not like there would really be any point in doing that, just curious
