OTRESC-BLDC-Controller-Hardware: common questions

What microcontroller does the OTRESC-BLDC-Controller-Hardware use?

The OTRESC-BLDC-Controller-Hardware is built around the ATSAMC21G, from the Microchip SAM family.

How big is the OTRESC-BLDC-Controller-Hardware PCB?

The OTRESC-BLDC-Controller-Hardware measures 33.3 × 33.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the OTRESC-BLDC-Controller-Hardware?

64 components, from 29 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 OTRESC-BLDC-Controller-Hardware design files?

From the otrebla333/OTRESC-BLDC-Controller-Hardware repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the OTRESC-BLDC-Controller-Hardware design in my own project?

Yes, under the terms of its GPL-3.0 license, which otrebla333 chose for the repository.

Can I test firmware for the OTRESC-BLDC-Controller-Hardware 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.
