well story behind is that i was always wanted mechanical keyboards, that cool looking keyboards with crazy lighting effects and keycaps. so i thought why not make one myself, i will learn lot new things, desgin my first PCB and also get myself my own custom keyboard. so started i

well story behind is that i was always wanted mechanical keyboards, that cool looking keyboards with crazy lighting effects and keycaps. so i thought why not make one myself, i will learn lot new things, desgin my first PCB and also get myself my own custom keyboard. so started it, did some research, components and everything related to it

it a keyboard that helps u write with per key rgb which u can control and create some cool and awsome effects. u can use it wired or wireless, with hotswappable keys. u can just change the type of keys if u wnat. all key anti ghost, with 65% layout and 68…

Keyboard bubble-: common questions

What microcontroller does the Keyboard bubble- use?

The Keyboard bubble- is built around the XIAO-nRF52840-Plus-SMD, from the Nordic nRF family.

How big is the Keyboard bubble- PCB?

The Keyboard bubble- measures 304.9 × 115.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Keyboard bubble-?

280 components, from 17 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 Keyboard bubble- design files?

From the vansh2966/keyboard-bubble- 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 Keyboard bubble- design in my own project?

The repository has no license, so all rights stay with vansh2966. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Keyboard bubble- without the hardware?

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