About the Fu keyboard PCB

Fu keyboard is an open source AVR/Arduino PCB design by PiKeeb, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 496.6 × 153.7 mm, with 586 components from 21 distinct parts.

Its main chip is the AT90USB1286-MU, from the AVR/Arduino family. By type, the board carries 182 relays, 182 LEDs, 8 capacitors, 5 resistors, 3 connectors and 1 IC.

It belongs with the keyboards designs in this gallery.

From the project

FU!Keyboard

- /bom contains the Bill of Material for PCB in interactive HTML format - /gerber contains the Gerber files for PCB production - /kicadproject contains the KiСad project files - /pcb3dmodel contains STEP 3D model of the PCB for with most of the components

NB: for opening the project files use the following version of KiCad (or newer):

There are 182 SK6812MINI-E RGB LEDs on the PCB that might trip the USB over-current protection on your PC/USB Hub. In that case, it's recommended to lower the maximum brightness of the LEDs AND to use the powered USB hub.

Fu keyboard: common questions

What microcontroller does the Fu keyboard use?

The Fu keyboard is built around the AT90USB1286-MU, from the AVR/Arduino family.

How big is the Fu keyboard PCB?

The Fu keyboard measures 496.6 × 153.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Fu keyboard?

586 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the Fu keyboard design files?

From the PiKeeb/fu-keyboard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Fu keyboard design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which PiKeeb chose for the repository.

Can I test firmware for the Fu keyboard without the hardware?

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