Kabeltester v2: common questions

What microcontroller does the Kabeltester v2 use?

The Kabeltester v2 is built around the RP2040, from the RP2040/RP2350 family.

How big is the Kabeltester v2 PCB?

The Kabeltester v2 measures 66 × 81 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Kabeltester v2?

63 components, from 25 distinct parts. The full bill of materials is listed on this page.

Where can I download the Kabeltester v2 design files?

From the luhbots/luhsoccer_electronics repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Kabeltester v2 design in my own project?

The repository has no license, so all rights stay with luhbots. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Kabeltester v2 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
