Doppler speed detector: common questions

What microcontroller does the Doppler speed detector use?

The Doppler speed detector is built around the Arduino_UNO_R3, from the AVR/Arduino family.

How many components are on the Doppler speed detector?

18 components, from 12 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 Doppler speed detector design files?

From the darksunnp/doppler_speed_detector repository on GitHub, which has the schematic and the BOM; the links under Design files point to each one.

Can I use the Doppler speed detector design in my own project?

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

Can I test firmware for the Doppler speed detector without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
