About the Kubisat main PCB

Kubisat main is an open source RP2040/RP2350 PCB design by gredzikk, published on GitHub under the MIT license. It is a 2-layer board measuring 80 × 80 mm, with 32 components from 27 distinct parts.

Its main chip is the DW01A, from the RP2040/RP2350 family. Other key parts include the DS3231M, LN2220, CN3791 and TP4056. By type, the board carries 11 resistors, 8 connectors, 5 ICs, 3 capacitors, 2 transistors and 1 battery holder.

It belongs with the rf & radio, sensors and science & space designs in this gallery.

From the project

Hardware and software of cubesat model for engineering thesis

Welcome to the KubiSat project! This repository contains all the necessary files to build your own small satellite based on the Raspberry Pi Pico, along with the corresponding ground station firmware. This project was originally conceived as an engineering thesis and has been open-sourced to be useful to a wider community.

The repository is organized into several key directories:

Kubisat main: common questions

What microcontroller does the Kubisat main use?

The Kubisat main is built around the DW01A, from the RP2040/RP2350 family.

How big is the Kubisat main PCB?

The Kubisat main measures 80 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Kubisat main?

32 components, from 27 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 Kubisat main design files?

From the gredzikk/kubisat 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 Kubisat main design in my own project?

Yes, under the terms of its MIT license, which gredzikk chose for the repository.

Can I test firmware for the Kubisat main 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.
