About the Kgc PCB

Kgc is an open source RP2040/RP2350 PCB design by szczurkosmiczny, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 200 × 100 mm, with 36 components from 20 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. Other key parts include the MAX7219. By type, the board carries 12 resistors, 10 diodes, 4 capacitors, 3 ICs and 1 buzzer.

From the project

Kerbal Guidance Computer

A HW flight computer for Kerbal Space Program inspired by NASA's DSKY - interface for Apollo Guidance Computer.

It consists of Python script for PC which grab data from the kRPC mod, KGC's DSKY based on Raspberry Pi Pico and program for it. DSKY communicate with PC via UART, so you also need some USB-UART converter. KiCad project for DSKY is located in kicad directory.

Kgc: common questions

What microcontroller does the Kgc use?

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

How big is the Kgc PCB?

The Kgc measures 200 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Kgc?

36 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the Kgc design files?

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

Can I use the Kgc design in my own project?

Yes, under the terms of its GPL-3.0 license, which szczurkosmiczny chose for the repository.

Can I test firmware for the Kgc 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.
