Cansat

About the Cansat PCB

Cansat is an open source RP2040/RP2350 PCB design by liberocan, published on GitHub under the CERN-OHL-W-2.0 license. It is a 2-layer board measuring 118 × 118 mm, with 25 components from 21 distinct parts.

Its main chip is the Pico, from the RP2040/RP2350 family. Other key parts include the DS1302+. By type, the board carries 9 ICs, 4 resistors, 2 connectors, 2 diodes, 1 crystal and 1 switch.

Cansat: common questions

What microcontroller does the Cansat use?

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

How big is the Cansat PCB?

The Cansat measures 118 × 118 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cansat?

25 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the Cansat design files?

From the liberocan/cansat-pcb repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Cansat design in my own project?

Yes, under the terms of its CERN-OHL-W-2.0 license, which liberocan chose for the repository.

Can I test firmware for the Cansat 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.
