About the Raspberrypi hat

Raspberrypi hat is an open source Raspberry Pi PCB design by AronAyub, published on GitHub. It is a 2-layer board measuring 27 × 18.8 mm, with 9 components from 6 distinct parts.

Its main chip is the Raspberry_Pi_2_3, from the Raspberry Pi family. Other key parts include the DHT22. By type, the board carries 4 resistors, 2 LEDs, 1 IC, 1 connector and 1 switch.

It belongs with the dev boards & breakouts designs in this gallery.

kicad design projects

In this repository I have provided my previous KICAD PCB Designs for: ### Arduino hat - this is a complete arduino hat, check the folder for files! it is among my first designs

- this is a simple power supply unit which accepts 12V, 1A and gives, 3V3 and 5V as output, it is among my first designs

- mini Pi Hat, one of my old PCB design projects !

Raspberrypi hat: common questions

What microcontroller does the Raspberrypi hat use?

The Raspberrypi hat is built around the Raspberry_Pi_2_3, from the Raspberry Pi family.

How big is the Raspberrypi hat?

The Raspberrypi hat measures 27 × 18.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Raspberrypi hat?

9 components, from 6 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 Raspberrypi hat design files?

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

Can I use the Raspberrypi hat design in my own project?

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

Can I test firmware for the Raspberrypi 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.
