Adafruit PyPortal: common questions

What microcontroller does the Adafruit PyPortal use?

The Adafruit PyPortal is built around the ATSAMD51J20, from the Microchip SAM family.

How big is the Adafruit PyPortal PCB?

The Adafruit PyPortal measures 88.3 × 64.5 mm and is 1.6 mm thick.

How many components are on the Adafruit PyPortal?

75 components, from 48 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 Adafruit PyPortal 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 Adafruit PyPortal 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 Adafruit PyPortal 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.
