Sensor board: common questions

What microcontroller does the Sensor board use?

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

How big is the Sensor board?

The Sensor board measures 176.6 × 134.6 mm, has 4 copper layers and is 4.69 mm thick.

How many components are on the Sensor board?

185 components, from 65 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 Sensor 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 Sensor 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 Sensor 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.
