Here are some calculations proving that this is actually possible:

I have estimated that the total mass of the key switches(125g), keycaps(100g), diodes(20g), PCB(150g), MCU(5g), and Plate(30g) will reach around 430 grams. With 6 pairs of magnets, and the weight of the PCB section spread out across all the magnets, each magnet will need only to lift around 70 grams. The magnets have 575 grams of pull/push force when…

Magno65-Keyboard: common questions

What microcontroller does the Magno65-Keyboard use?

The Magno65-Keyboard is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the Magno65-Keyboard PCB?

The Magno65-Keyboard measures 354.8 × 131 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Magno65-Keyboard?

135 components, from 7 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 Magno65-Keyboard design files?

From the couchpotatoe1234/Magno65-Keyboard 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 Magno65-Keyboard design in my own project?

The repository has no license, so all rights stay with couchpotatoe1234. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Magno65-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.
