About the Linear Keyboard PCB

Linear Keyboard is an open source RP2040/RP2350 PCB design by Jyst7, published on GitHub. It is a 2-layer board measuring 142 × 95.2 mm, with 182 components from 8 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. By type, the board carries 84 diodes, 42 switches, 42 capacitors, 8 resistors, 2 ICs and 2 connectors.

It belongs with the keyboards and displays & leds designs in this gallery.

From the project

Wired Corne Keyboard with rpi2040(Orpheus Pico) with all the usb-c goodness!

This is a modified Corne keyboard. It is connected with usb-c as well as has two 0.91" OLED's right on top of the two Pi Pico's. The keyboard has 18 keys on each side plus an extra 3 per side for thumb keys, overall 42 keys with rgb led's for each key.

Linear Keyboard: common questions

What microcontroller does the Linear Keyboard use?

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

How big is the Linear Keyboard PCB?

The Linear Keyboard measures 142 × 95.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Linear Keyboard?

182 components, from 8 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 Linear Keyboard design files?

From the Jyst7/Linear_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 Linear Keyboard design in my own project?

The repository has no license, so all rights stay with Jyst7. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Linear 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.
