Overview
Current Probe is an open-source printed circuit board by Qeteshpony, from the Qeteshpony/Current-Probe repository on GitHub, published under the BSD-2-Clause licence. It is a 2-layer board of 32 × 47.5 mm with 10 parts on 2 nets, routed with 2 tracks and 20 vias.
Its parts include 3 connectors and 1 resistor. It belongs with the sensors and measurement boards of this library.
README
README.mdCurrent-Probe
A simple board to turn any oscilloscope into a current meter by running the load through the 4mm Terminals and connecting your oscilloscope to the BNC terminal.
The resistor footprint takes a 2512 SMD resistor which usually come with a rating of 1 to 3, sometimes 5 watts which is enough to run several amps through this board.
The connector footprints are made for the Altech/Hirschmann PB 4 4mm test jacks that take a standard 4mm test lead.
The BNC connector footprint is for the Amphenol B6252HB but there's lots of cheap, compatible connectors with the same footprint available
You can also use the M3 screw holes to connect to this board since they are wired in parallel to the connectors closest to each.

Questions
How big is the Current Probe PCB?
It measures 32 × 47.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Current Probe use?
10 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Current Probe KiCad files?
From the Qeteshpony/Current-Probe repository on GitHub, at the commit this page was made from: the board is pcb/Current-Probe.kicad_pcb and its schematic pcb/Current-Probe.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Current Probe design in my own project?
Its repository publishes it under the BSD-2-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
