About the Keezyboost40 PCB

Keezyboost40 is an open source RP2040/RP2350 PCB design by ChrisChrisLoLo, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 217.6 × 68.1 mm, with 83 components from 5 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. Other key parts include the ST7735_1.8inch. By type, the board carries 41 switches, 40 diodes and 2 ICs.

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

From the project

4x10 ortholinear with an LCD in the middle. Uses the Raspberry Pi Pico, as well as Rust firmware

A 4x10 low profile ortholinear keyboard with an lcd screen in the center. Uses the Raspberry Pi Pico as well as firmware written in Rust (though QMK works too*)

I need to fix a bug with the animation slowing down, though I suspect it'll mostly involve tinkering with RTOS timings

Keezyboost40: common questions

What microcontroller does the Keezyboost40 use?

The Keezyboost40 is built around the Pico, from the RP2040/RP2350 family.

How big is the Keezyboost40 PCB?

The Keezyboost40 measures 217.6 × 68.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Keezyboost40?

83 components, from 5 distinct parts. The full bill of materials is listed on this page.

Where can I download the Keezyboost40 design files?

From the ChrisChrisLoLo/keezyboost40 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Keezyboost40 design in my own project?

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

Can I test firmware for the Keezyboost40 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.
