Calcite60 Keyboard: common questions

What microcontroller does the Calcite60 Keyboard use?

The Calcite60 Keyboard is built around the RP2040, from the RP2040/RP2350 family.

How big is the Calcite60 Keyboard PCB?

The Calcite60 Keyboard measures 295 × 105 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Calcite60 Keyboard?

188 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the Calcite60 Keyboard design files?

From the siderakb/ms60 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Calcite60 Keyboard design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which siderakb chose for the repository.

Can I test firmware for the Calcite60 Keyboard 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.
