Airspeed SensorBoard: common questions

What microcontroller does the Airspeed SensorBoard use?

The Airspeed SensorBoard is built around the STM32F030F4PX, from the STM32 family.

How big is the Airspeed SensorBoard PCB?

The Airspeed SensorBoard measures 31.5 × 46.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Airspeed SensorBoard?

38 components, from 18 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 Airspeed SensorBoard design files?

From the pms67/Airspeed_SensorBoard repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Airspeed SensorBoard design in my own project?

Yes, under the terms of its MIT license, which pms67 chose for the repository.

Can I test firmware for the Airspeed SensorBoard 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.
