About the Shiftboard PCB

Shiftboard is an open source RP2040/RP2350 PCB design by JamFox, published on GitHub. It is a board, with 61 components from 3 distinct parts.

Its main chip is the RP2040-ZERO, from the RP2040/RP2350 family. By type, the board carries 54 switches and 1 IC.

It belongs with the keyboards and iot & wireless designs in this gallery.

From the project

Shiftboard keyboard is a custom ergonomic split RP2040 and shiftregister based mechanical keyboard.

Shiftboard is a custom ergonomic split mechanical keyboard.

- [x] 4x6 column staggered keys and 2x3 thumb clusters - Leftmost 4x1 or topmost 1x6 part of the PCB can be snapped off - [x] QMK supported microcontroller(s) - RP2040 not officially supported yet, but solutions exist and work is underway to support it. Python based firmware solutions offered as an alternative. - [x] Direct mapped pins, shift-register or IO expander to eliminate need for matrix diodes - 74HC165 shift-registers used - [ ] Built-in controller for lowest profile - Dropped, in favor of hassle free plug-in and more…

Shiftboard: common questions

What microcontroller does the Shiftboard use?

The Shiftboard is built around the RP2040-ZERO, from the RP2040/RP2350 family.

How many components are on the Shiftboard?

61 components, from 3 distinct parts. The full bill of materials is listed on this page.

Where can I download the Shiftboard design files?

From the JamFox/Shiftboard repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the Shiftboard design in my own project?

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

Can I test firmware for the Shiftboard 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.
