Description

Dear friends, good news! The Probe is assembled and checked, works correctly. Checked from the built-in generator at 15MHz (generator limit).

This is a low cost logic analyzer probe for oscilloscope Rigol MSO5000 with fixded CMOS/TTL logic for 3.3/5.0V input levels with full bandwidth (up to 600MHz if it realy happens during research). It can also be connected to other models with an adapter or using a different cable.

All components are accessible on LCSC. You can order board and all components for about $20 (plus shipping) in a couple of clicks.

Of course, you will not get beautiful wires with tags for half of the price of an oscilloscope cost for (fuck them) $400!

Actual version 2.1. Please, check and swith designe to version to 2.1.

Thanks to guys from EEVblog for pinout of the connector!

I recommend replacing R17.
I used 100 Om, but the led was very bright, replace to 5.1 kOm.

New version 2.1


Change LDO from lm1117 to MC33375ST-3.3T3G because the lm1117 has a large drop voltage and does not provide 3.3V power when powered from a 4V oscilloscope power line.
