Output board: common questions

What microcontroller does the Output board use?

The Output board is built around the STM32F105VBH6, from the STM32 family.

How big is the Output board?

The Output board measures 113.2 × 84.1 mm, has 4 copper layers and is 4.69 mm thick.

How many components are on the Output board?

120 components, from 33 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 Output board design files?

From the SEDS-PSU/avionics 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 Output board design in my own project?

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

Can I test firmware for the Output board 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.
