Overview
Cable Test Remote is an open-source printed circuit board by juniperlynx, from the juniperlynx/Cable-Tester repository on GitHub, published under the MIT licence. It is a 2-layer board of 25.4 × 95.9 mm with 23 parts on 10 nets, routed with 210 tracks and 0 vias.
It is built around the RJ45. Its parts include 18 diodes and 2 connectors.
Main components
1README
README.mdCable-Tester
This is a replacement PCB and software for a cheap commercial cable tester usually sold as the HL-486 (though there are other model numbers, mine is ST-M810). It improves on the original design by adding beefier drive circuitry and a proper voltage regulator for the microcontroller.
Schematics and PCB layouts are available for both ends. The current revision of the Gerbers is untested but only contains slight variations from the most recently ordered version. Complete BOMs for both the master and remote ends are now available for both ends along with Digikey shoping carts in .csv format. I haven't been able to find a source for the multi-LED standoffs used to space the strand indicator LEDs so I've modeled a part in OpenSCAD. The OpenSCAD source and a rendered .stl file are available but untested at this time.
The original Kicad design files are in "Kicad Files/" and the software source code in "Software/". If you'd like to build your own use the Gerber files in "Gerbers/" and the BOMs in "BOM/" along with the standoff model in "3D Parts/STL"

Questions
How big is the Cable Test Remote PCB?
It measures 25.4 × 95.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cable Test Remote use?
23 parts, built around the RJ45. 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 Cable Test Remote KiCad files?
From the juniperlynx/Cable-Tester repository on GitHub, at the commit this page was made from: the board is Kicad Files/Remote/Cable Test Remote.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cable Test Remote design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
