About the Kinpi PCB

Kinpi is an open source RP2040/RP2350 PCB design by echristophe, published on GitHub. It is a 2-layer board measuring 108 × 84.5 mm, with 15 components from 9 distinct parts.

Its main chip is the RaspberryPi_Pico, from the RP2040/RP2350 family. By type, the board carries 6 connectors, 4 LEDs, 4 resistors and 1 module.

It belongs with the keyboards designs in this gallery.

From the project

kinPi is an open-source replacement controller for the Kinesis Advantage keyboard, powered by the Raspberry Pi RP2040 microcontroller.

kinPi is an open-source replacement controller for the Kinesis Advantage keyboard, powered by the Raspberry Pi RP2040 microcontroller.

It allows you to upgrade your classic Kinesis Advantage with modern features, including full QMK support, customizable layers, and low-latency performance.

- Microcontroller: Raspberry Pi RP2040 (Raspberry Pi Pico / Pico H). - Plug-and-Play Matrix: Directly connects to original Kinesis 13-pin flexible circuits and thumb clusters (15×7 matrix). - Modern Firmware: Powered by QMK Firmware with support for: - NKRO & mouse emulation. - Home-row modifiers, combos…

Kinpi: common questions

What microcontroller does the Kinpi use?

The Kinpi is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the Kinpi PCB?

The Kinpi measures 108 × 84.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Kinpi?

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

Where can I download the Kinpi design files?

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

Can I use the Kinpi design in my own project?

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

Can I test firmware for the Kinpi 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.
