About the Sampler keyboard PCB

Sampler keyboard is an open source RP2040/RP2350 PCB design by aizuknight, published on GitHub. It is a 2-layer board measuring 66.7 × 66.7 mm, with 19 components from 4 distinct parts.

Its main chip is the XIAO-RP2040-DIP, from the RP2040/RP2350 family. By type, the board carries 6 switches, 6 LEDs, 6 diodes and 1 IC.

It belongs with the keyboards designs in this gallery.

Sampler keyboard: common questions

What microcontroller does the Sampler keyboard use?

The Sampler keyboard is built around the XIAO-RP2040-DIP, from the RP2040/RP2350 family.

How big is the Sampler keyboard PCB?

The Sampler keyboard measures 66.7 × 66.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Sampler keyboard?

19 components, from 4 distinct parts. The full bill of materials is listed on this page.

Where can I download the Sampler keyboard design files?

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

Can I use the Sampler keyboard design in my own project?

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

Can I test firmware for the Sampler 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.
