Mearm pi hat: common questions

What microcontroller does the Mearm pi hat use?

The Mearm pi hat is built around the Raspberry_Pi_+_Conn, from the Raspberry Pi family.

How big is the Mearm pi hat?

The Mearm pi hat measures 65 × 56.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Mearm pi hat?

24 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the Mearm pi hat design files?

From the mimeindustries/mearm-pi-hat-pcb repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Mearm pi hat design in my own project?

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

Can I test firmware for the Mearm pi hat 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.
