From the project

ZeroDriver - Arduino Zero Compatible SAMd21 based dual motor driver for robotics projects.

ZeroDriver is an Arduino Zero-compatible dual-motor driver board for robotics and mechatronics projects.

Robotics projects usually need two boards - a microcontroller board and a separate driver for the motors. ZeroDriver combines both in one for your convenience.

ElectronutLabs-ZeroDriver: common questions

What microcontroller does the ElectronutLabs-ZeroDriver use?

The ElectronutLabs-ZeroDriver is built around the SAMD21G18A, from the Microchip SAM family.

How big is the ElectronutLabs-ZeroDriver PCB?

The ElectronutLabs-ZeroDriver measures 60 × 22.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ElectronutLabs-ZeroDriver?

41 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the ElectronutLabs-ZeroDriver design files?

From the electronut/ElectronutLabs-ZeroDriver repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the ElectronutLabs-ZeroDriver design in my own project?

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

Can I test firmware for the ElectronutLabs-ZeroDriver 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.
