Dear friends, good news! The Probe is assembled and checked, works correctly. Checked at 160MHz. 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!
