content: One of my recent projects has been to make a custom mechanical keyboard and I was hoping to make also a custom trackball but researching what kind of sensor could be used I have found that all of them are obsolete!Does anyone know a "mouse sensor" IC that can be purchased in low quantities on the regular distributors?Parts like ADNS-7700 from Avago, VD5377 from ST, CYONS1001 from Cypress are all obsolete and without replacement... Apart from finding a suitable IC I just find it curious that basically all the ICs for this application have banished from the market!I have only found ICs from the company pixart like the PAW3305DK but doesn't seem to be available outside aliexpress and I'm not sure if this is an active part or not...

content: Hi,I just started researching this myself... Did you ever find any suitable sensors that are not obsolete?

content: For a one-ish off project, you are overthinking this. Go down to the nearest dollar store, buy a bucket 'o mice, use whatever chip is in them.

content: It seems Broadcom got out of this marker. There is the Parallax MCS-12086, Mouser got the evaluation board, but not the part.

content: I'm a bit confused. Why would you use an optical mouse sensor for a trackball? Will the trackball surface be patterned, or how would it function?

content: After some more digging, Pixart now sells the ADNS parts under its own brand. Still can't get those on Digikey or Mouser.

content: Hey, this thread looks dead, but I'm interested in finding the replacement for the ADNS parts.I happen to be sitting on a small pile of the ADNS 2610 (100+) and want to find what the next gen is.Did any of you find this?

content: Hi, just jumping on this topic as I see it went unanswered.Regarding some of the parts mentioned in this thread:Pixart PAW3305DK (This part is no longer available from Pixart)Pixart ADNS-3050 (Not recommended for new designs, replacement is the PMW3325DB-TWV1)Pixart ADNS-9800 (This is an active part)In Europe, these parts are available from EPS Global:https://www.epsglobal.com/manufacturers/pixart

content: As texaspyro says, find an old optical mouse. You need not just the IC, but the optics that go with it too. They are all salvageable from an old optical mouse.The ones that use HDNS2000 (H2000) or OM02 give you the option of quadrature X-Y output signals too.https://www.eevblog.com/forum/projects/mousesensors-lots-of-pictures/My library of Optical mouse sensor datasheets and articles attached below...P.S. I didn't notice this was a necropost.

content: You cannot simply use an off the shelf mouse for that because the movements will be inverted.
