Overview

RPi FS HAT is an open-source printed circuit board by futureshocked, from the futureshocked/KicadLikeAPro-Project-2-RaspberryPiFullStackHAT repository on GitHub, published under the MIT licence. It is a 2-layer board of 27.9 × 17.8 mm with 10 parts on 17 nets, routed with 72 tracks and 7 vias.

It is built around the DHT22. Its parts include 4 resistors, 2 diodes, 1 IC, 1 connector and 1 switch.

Kicad Like A Pro - Project 2 - Raspberry Pi Full Stack HAT

This repository contains the PCB design project from the book and course "Kicad Like a Pro"

In this project you will build on the knowledge and skill of the previous two project and design an Arduino-compatible board using, mostly, surface-mounted components.

The board will contain a micro controller, two EEPROM modules, a clock and calendar module, two crystal oscillators, and several SMD-sized resistors, capacitors and LEDs. In addition, it will include headers for connecting peripherals to the micro controller.

All this, in a relatively small board, measuring 44x28 mm. Working on this board will give you the opportunity to explore some of Kicad’s powerful features, such as splitting schematic diagrams into more than one sheets, using an external autorouter, and converting a two-layer board into a four layer board.

The name I have given to this board is “Battery powered Arduino with clock and extended EEPROM”. Or, let’s call it “BACEE”, for short.

Questions

How big is the RPi FS HAT PCB?

It measures 27.9 × 17.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the RPi FS HAT use?

10 parts, built around the DHT22. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the RPi FS HAT KiCad files?

From the futureshocked/KicadLikeAPro-Project-2-RaspberryPiFullStackHAT repository on GitHub, at the commit this page was made from: the board is RPi FS HAT.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the RPi FS HAT design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
