Obc db: common questions

What microcontroller does the Obc db use?

The Obc db is built around the STM32F030F4P6, from the STM32 family.

How big is the Obc db PCB?

The Obc db measures 90.2 × 95.9 mm, has 4 copper layers and is 4.69 mm thick.

How many components are on the Obc db?

44 components, from 34 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 Obc db design files?

From the queens-satellite-team/pcbs 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 Obc db design in my own project?

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

Can I test firmware for the Obc db without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
