About the Jamboard PCB

Jamboard is an open source RP2040/RP2350 PCB design by Jam12390, published on GitHub. It is a 2-layer board measuring 332.6 × 171.1 mm, with 247 components from 9 distinct parts.

Its main chip is the Raspberry_Pi_Pico, from the RP2040/RP2350 family. By type, the board carries 164 diodes, 82 switches and 1 IC.

It belongs with the keyboards designs in this gallery.

We're so back with v2. This is a 75% keyboard which I designed over the course of a couple of days back in Feb for fun and to see just how hard designing a keyboard could be! (Minor note: I know the branding on the case says "Just Another Hackboard". That was the original name for the project and is the branding I want for the keyboard. + I'm printing the case myself so it shouldn't be an issue.)

Jamboard: common questions

What microcontroller does the Jamboard use?

The Jamboard is built around the Raspberry_Pi_Pico, from the RP2040/RP2350 family.

How big is the Jamboard PCB?

The Jamboard measures 332.6 × 171.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Jamboard?

247 components, from 9 distinct parts. The full bill of materials is listed on this page.

Where can I download the Jamboard design files?

From the Jam12390/Jamboard repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Jamboard design in my own project?

The repository has no license, so all rights stay with Jam12390. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Jamboard 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.
