MS05000 Budget Logic Analyzer Probe Set Design
clytle374:
Just got my 5 boards, they look great. Finally got a couple days off to get parts ordered, anyway the following were out of stock
ALT U3 was out of stock, able to find in alternate packaging.
D1 out of stock, replaced with thicker LED https://www.digikey.com/en/products/detail/LTST-C190KGKT/160-1435-1-ND/386814?itemSeq=357480811
C1 was out of stock, replaced with https://www.digikey.com/en/products/detail/C0805C475K8PACTU/399-3133-1-ND/551638?itemSeq=357482706
Hopefully I didn't make a mistake there anywhere. Be a few weeks as I have other things on the bench and apart needing their turn on the bench.
Thanks
Cory

Thank you for the boards, built one 3.3V and it works great! (despite me less than ideal tools since I just moved) I'm not a monster I cleaned them after taking the pics.
I also found ALT U3 was out of stock for the 5V Version.
TI does have SN74LXC8T245s available so I ordered some of those.
Any component differences expected or can we fit the rest as if it was a 5V version?
PS: No idea why it decided to rotate my images.
Deckardsvr:
just finished the boards, it's working great ! Thank you Gandalf_Sr :-+
I had to order the parts from Mouser, it's easier than DK for me; just had to change the 50pin Header Ref. which they didn't have : replacement 3M 6850-4500PL, it fits nicely.
Someone mentioned that the USB Port could be used as a VExt. source, thanks for the tip ;D

Hi @Gandalf_Sr
The specification for the LA in the manual appear to be those of the active probe. Do you have details of the specification of the port on the MSO5000. Like max voltage.

Sorry this has been a long time in replying. Clearly the MSO5000 official probe can take much higher logic voltages than 5V but my probes are limited by the minimum and maximum voltages which are dictated by the min/mac Vcc for whatever voltage level translator IC you use for U3. Basically you can go up to 6.5V logic depending on what U3 is fitted.
