Oresat adcs card: common questions

What microcontroller does the Oresat adcs card use?

The Oresat adcs card is built around the STM32F042K6T7, from the STM32 family.

How big is the Oresat adcs card PCB?

The Oresat adcs card measures 99.8 × 94.6 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Oresat adcs card?

579 components, from 73 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 Oresat adcs card design files?

From the oresat/oresat-adcs-hardware 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 Oresat adcs card design in my own project?

Yes, under the terms of its GPL-2.0 license, which oresat chose for the repository.

Can I test firmware for the Oresat adcs card 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.
