Piweather: common questions

What microcontroller does the Piweather use?

The Piweather is built around the M20-7812045R, from the Raspberry Pi family.

How big is the Piweather PCB?

The Piweather measures 65 × 64 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Piweather?

58 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the Piweather design files?

From the pluggee/piweather repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Piweather design in my own project?

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

Can I test firmware for the Piweather without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
