GrBLDC: common questions

What microcontroller does the GrBLDC use?

The GrBLDC is built around the ATMEGA16M1-A, from the AVR/Arduino family.

How big is the GrBLDC PCB?

The GrBLDC measures 103.1 × 59.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the GrBLDC?

204 components, from 41 distinct parts. The full bill of materials is listed on this page.

Where can I download the GrBLDC design files?

From the Defdist/GrBLDC3 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the GrBLDC design in my own project?

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

Can I test firmware for the GrBLDC 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.
