CableTester
About the CableTester PCB
CableTester is an open source PCB design by IoannisP-ITENG, published on GitHub under the MIT license. It is a 4-layer board measuring 50 × 50 mm, with 104 components from 8 distinct parts.
From the project
USB type-C and UTP cable tester designed in faebryk
USB type-C and UTP cable tester designed in faebryk
This is a simple USB type-C and UTP cable continuity tester. It lights up the LED corresponding to the strand it is testing when there is an electrical connection. The tester is powered with 5V via the PD compliant USB type-C connector.
This project is build with the open-source EDA faebryk.
This project is usefull as a simple cable tester for UTP and USB type-C cables, however it is very easy to add additional connectors for different cable types due to faebryk.
