Bldc driver: common questions
What microcontroller does the Bldc driver use?
The Bldc driver is built around the ATmega328PB-AU, from the AVR/Arduino family.
How big is the Bldc driver PCB?
The Bldc driver measures 46.5 × 26.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Bldc driver?
67 components, from 26 distinct parts. The full bill of materials is listed on this page.
Where can I download the Bldc driver 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 Bldc driver 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 Bldc driver 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.
