STS1 COBC: common questions
What microcontroller does the STS1 COBC use?
The STS1 COBC is built around the STM32F411RET6TR, from the STM32 family.
How big is the STS1 COBC PCB?
The STS1 COBC measures 81 × 85 mm, has 4 copper layers and is 1.6062 mm thick.
How many components are on the STS1 COBC?
300 components, from 111 distinct parts. The full bill of materials is listed on this page.
Where can I download the STS1 COBC design files?
From the SpaceTeam/STS1_COBC_HW repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the STS1 COBC design in my own project?
Yes, under the terms of its CC-BY-4.0 license, which SpaceTeam chose for the repository.
Can I test firmware for the STS1 COBC 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.
