About the Nyan keys PCB

Nyan keys is an open source STM32 PCB design by portlandhodl, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 284.7 × 94.2 mm, with 138 components from 36 distinct parts.

Its main chip is the STM32F723VETX, from the STM32 family. Other key parts include the ICE40HX4K-TQ144, TPS70345 and 24LC1025. By type, the board carries 61 relays, 38 capacitors, 16 resistors, 9 switches, 6 diodes and 4 ICs.

It belongs with the keyboards designs in this gallery.

Hardware document for the nyan keys keyboard

Made with ❤️ by Portland.HODL - If you like my work please submit PRs and or like/star my repos.

Personal use is completely premised for this so if you want to make one for yourself or mod it feel free!

If you would like to avoid the logistics of acquiring the parts and getting a board made. I can fabricate and assemble boards on request. Please just email admin@qrsnap.io.

Nyan keys: common questions

What microcontroller does the Nyan keys use?

The Nyan keys is built around the STM32F723VETX, from the STM32 family.

How big is the Nyan keys PCB?

The Nyan keys measures 284.7 × 94.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Nyan keys?

138 components, from 36 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 Nyan keys design files?

From the portlandhodl/nyan-keys-hardware 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 Nyan keys design in my own project?

Yes, under the terms of its Apache-2.0 license, which portlandhodl chose for the repository.

Can I test firmware for the Nyan keys without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
