Dynossat edu obc: common questions

What microcontroller does the Dynossat edu obc use?

The Dynossat edu obc is built around the ATSAMD51J20A-AU, from the Microchip SAM family.

How big is the Dynossat edu obc PCB?

The Dynossat edu obc measures 42 × 42 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Dynossat edu obc?

52 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 Dynossat edu obc design files?

From the BHDynamics/dynossat-edu-obc repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Dynossat edu obc design in my own project?

Yes, under the terms of its CERN-OHL-1.2 license, which BHDynamics chose for the repository.

Can I test firmware for the Dynossat edu obc without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
