About the Keyboard sliderpad PCB

Keyboard sliderpad is an open source RP2040/RP2350 PCB design by kermitsgonnakermicide, published on GitHub. It is a 2-layer board measuring 61 × 131 mm, with 10 components from 4 distinct parts.

Its main chip is the XIAO-RP2040-DIP, from the RP2040/RP2350 family. By type, the board carries 4 connectors, 3 resistors, 2 switches and 1 IC.

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

From the project

a modular keyboard(w/ i2c!)

Lattice also comes with three modules(as of now), which are: - a 16 key macropad with an OLED - a 3 slider, two encoder module i'm calling the sliderpad - a 32x4 RGB LED(specifically the WS2812B-2020) matrix that slides in the empty top bit of the keyboard(connected by 2.54 mm pins because I didnt trust the current limits of the magnetic connectors)

Each module features a xiao rp2040 to run everything else on it because its so smol and cute :3

Keyboard sliderpad: common questions

What microcontroller does the Keyboard sliderpad use?

The Keyboard sliderpad is built around the XIAO-RP2040-DIP, from the RP2040/RP2350 family.

How big is the Keyboard sliderpad PCB?

The Keyboard sliderpad measures 61 × 131 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Keyboard sliderpad?

10 components, from 4 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 Keyboard sliderpad design files?

From the kermitsgonnakermicide/Lattice 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 Keyboard sliderpad design in my own project?

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

Can I test firmware for the Keyboard sliderpad 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.
