About the MSCKee PCB

MSCKee is an open source RP2040/RP2350 PCB design by Creative-Difficulty, published on GitHub. It is a 4-layer board measuring 213.7 × 140.6 mm, with 140 components from 30 distinct parts.

Its main chip is the RP2040, from the RP2040/RP2350 family. Other key parts include the PCA9956BTWY, W25Q128JVSIQ, NCP1117LPST33T3G, OPT3001DNPR and MCP23017T-E/ML. By type, the board carries 41 diodes, 36 LEDs, 25 capacitors, 20 resistors, 9 ICs and 3 connectors.

It belongs with the keyboards and sensors designs in this gallery.

From the project

Split Keyboard for Hack Club Outpost with dual light sensors, per-key addressable backlighting, integrated RP2040 MCU

msCKee is an open source split Keyboard with per-key white backlighting, and two light sensors, adapting to ambient brightness.

It features: - dimmable white backlighting for every key, programmable to display animations - two light sensors (one per side) to automatically dim backlight - Integrated RP2040 MCU IC - Minimalist aluminium enclosure - USB-C 2.0 connectivity - 4 layer board: Signal - GND - 3,3V and 5V split pour - Signal - RJ9 cable connection between halves - Cherry MX 5 pin switch compatible

MSCKee: common questions

What microcontroller does the MSCKee use?

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

How big is the MSCKee PCB?

The MSCKee measures 213.7 × 140.6 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the MSCKee?

140 components, from 30 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 MSCKee design files?

From the Creative-Difficulty/mSCKee 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 MSCKee design in my own project?

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

Can I test firmware for the MSCKee 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.
