MKRZero V5.0: common questions

What microcontroller does the MKRZero V5.0 use?

The MKRZero V5.0 is built around the ATSAMD21G18A-48, from the Microchip SAM family.

How big is the MKRZero V5.0 PCB?

The MKRZero V5.0 measures 61.5 × 25 mm and is 1.6 mm thick.

How many components are on the MKRZero V5.0?

91 components, from 55 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 MKRZero V5.0 design files?

From the hulkco/oshwi repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the MKRZero V5.0 design in my own project?

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

Can I test firmware for the MKRZero V5.0 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.
