About the Win split right PCB

Win split right is an open source RP2040/RP2350 PCB design by alexcamlo, published on GitHub. It is a 2-layer board measuring 213.2 × 120.4 mm, with 173 components from 15 distinct parts.

Its main chip is the RP2040_ProMicro, from the RP2040/RP2350 family. Other key parts include the 74AHCT1G125. By type, the board carries 40 capacitors, 39 LEDs, 39 diodes, 2 ICs, 2 switches and 1 connector.

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

From the project

Inspired by the Boardrun Bizarre and Red herring. I wanted to be able to use a normal keyset, so no full ortho, but split.

This is my first designed keyboard from the grounds up. I'm not responsible for any damage caused by using this keyboard or any production of this keyboard that doesn't work.

- 2x RP2040 Pro Micro. - 70x pin headers - 1x Skyloong Rotary Encoder. - 2x TRRS Connector. - 2x SMD Buttons. - 2x 128x32 OLED panels. - 73x Kailh hotswap sockets. - 73x SK6812MINI-E leds. - 4x 2u Stabilizers. - 16x M2 6mm screws.

Win split right: common questions

What microcontroller does the Win split right use?

The Win split right is built around the RP2040_ProMicro, from the RP2040/RP2350 family.

How big is the Win split right PCB?

The Win split right measures 213.2 × 120.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Win split right?

173 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the Win split right design files?

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

Can I use the Win split right design in my own project?

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

Can I test firmware for the Win split right 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.
