Warning: This Board is currently under development. Simply fabricating it doesn't mean it would work! See v0.1BUILDLOG.md for some problems found while building the first prototype.

A big thanks to the Shuttleworth Foundation for supporting the development of this Project.

HighPower-Mechaduino: common questions

What microcontroller does the HighPower-Mechaduino use?

The HighPower-Mechaduino is built around the SAMD21G18A-A, from the Microchip SAM family.

How big is the HighPower-Mechaduino PCB?

The HighPower-Mechaduino measures 60 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the HighPower-Mechaduino?

117 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the HighPower-Mechaduino design files?

From the pointhi/HighPower-Mechaduino repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the HighPower-Mechaduino design in my own project?

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

Can I test firmware for the HighPower-Mechaduino 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.
