Pine: common questions

What microcontroller does the Pine use?

The Pine is built around the ATSAMD21G18A-AUT, from the Microchip SAM family.

How big is the Pine PCB?

The Pine measures 45.7 × 38.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pine?

43 components, from 22 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 Pine design files?

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

Can I use the Pine design in my own project?

Yes, under the terms of its MIT license, which hutscape chose for the repository.

Can I test firmware for the Pine 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.
