The KiCad project lives in the Jubakuba/Keycult-TKL-Kicad repository on GitHub; these links point at the commit this page was built from.

Keycult-TKL: common questions

What microcontroller does the Keycult-TKL use?

The Keycult-TKL is built around the RP2040, from the RP2040/RP2350 family.

How big is the Keycult-TKL PCB?

The Keycult-TKL measures 347.9 × 119.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Keycult-TKL?

390 components, from 23 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Keycult-TKL design files?

From the Jubakuba/Keycult-TKL-Kicad repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Keycult-TKL design in my own project?

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

Can I test firmware for the Keycult-TKL 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.
