Quad rotor: common questions
What microcontroller does the Quad rotor use?
The Quad rotor is built around the ATSAMS70J19A, from the Microchip SAM family.
How big is the Quad rotor PCB?
The Quad rotor measures 27.3 × 16.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Quad rotor?
40 components, from 21 distinct parts. The full bill of materials is listed on this page.
Where can I download the Quad rotor design files?
From the acshi/quad_rotor repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Quad rotor design in my own project?
The repository has no license, so all rights stay with acshi. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Quad rotor without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Microchip SAM firmware against it before you order a PCB.
