About the Raspberry-PI-HAT

Raspberry-PI-HAT is an open source Raspberry Pi PCB design by gathonjia-ndungu, published on GitHub. It is a 2-layer board measuring 28.2 × 18.8 mm, with 8 components from 7 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, 1 IC, 1 connector, 1 switch and 1 diode.

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

From the project

A foundational KiCad design project for a custom Raspberry Pi HAT.

A foundational KiCad design project for a custom Raspberry Pi HAT.

This repository contains the complete KiCad project files for a Raspberry Pi HAT (Hardware Attached on Top) expansion board. It provides the schematic and PCB layout files, enabling hardware enthusiasts, makers, and engineers to explore, modify, and manufacture their own custom HATs. Whether you're looking to integrate specific sensors, add custom I/O, or create a power management solution, this design serves as an excellent starting point for developing custom hardware for the Raspberry Pi.

Raspberry-PI-HAT: common questions

What microcontroller does the Raspberry-PI-HAT use?

The Raspberry-PI-HAT is built around the Raspberry_Pi_2_3, from the Raspberry Pi family.

How big is the Raspberry-PI-HAT?

The Raspberry-PI-HAT measures 28.2 × 18.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Raspberry-PI-HAT?

8 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Raspberry-PI-HAT design files?

From the gathonjia-ndungu/Raspberry-PI-HAT repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Raspberry-PI-HAT design in my own project?

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

Can I test firmware for the Raspberry-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.
