The HAT RACK is a DIN rail carrier board for Raspberry Pi HATs which makes it easy to connect multiple add-on boards together. It's plug & play and can be daisy chained without any special adapters, ribbon cables or messy wires!

Stackable HATs have become the de facto standard in the Raspberry Pi community, but stacking HATs together can make them difficult to get to, awkward to maintain and can lead to excessive heat build-up.

The HAT RACK solves this by separating the stack into an easier to manage array. Each board is connected together in parallel which is perfect for I2C based HATs such as Raspberry Pi's Sense HAT.

One HAT RACK board supports 3 HATs or 6 pHATs with a Raspberry Pi mounted in 1 of 2 positions. It's incredibly versatile and can be configured in loads of different ways.

Features

There are other HAT mounts available, so how is the HAT RACK different?

• Connect 3 HATs or 6 pHATs per board
• Plug & Play Raspberry Pi or Pi Zero
• Daisy chain multiple boards
• DIN rail mountable
• External power in
• BCM pin numbering
• Gold flash plated connectors

BCM pin numbering makes it easy to identify the pinouts, and an external power-in allows HAT RACK to be powered from a dedicated 5V power supply if needed.

A single HAT RACK board will fit into a standard 12 module DIN rail enclosure with plenty space for cables or larger add-on boards.

Home Automation Applications

Combine any number of Raspberry Pi add-on boards to create your own ideal automation system. The modular plug & play design means it's easy to maintain and expandable!

Industrial Control Applications

The HAT RACK is the ideal solution for industrial control applications where conventional PLCs may offer capabilities beyond the requirements of small scale manufacturing, machining or prototyping.

Developers can rapidly implement dedicated industrial automation systems using Raspberry Pi add-on boards.

3D Model

We have released an interactive 3D model which you can use in your designs.

Compatibility

The HAT RACK is compatible with all 40-way Raspberry Pi models and clones.

• Raspberry Pi 1 Model A+/B/B+
• Raspberry Pi 2 Model B
• Raspberry Pi 3 Model B/B+
• Raspberry Pi 4
• Raspberry Pi 5
• Raspberry Pi Zero
• Raspberry Pi Zero 2
• ATMegaZero
• Asus Tinker Board
• Banana Pi
• Odroid
• Orange Pi
• RockPi

HATs which make use of the PoE header (such as the official PoE HAT), are supported by attaching directly to the Pi using extended/stacking headers.

Of-course, not all HATs will play nicely together. For non bus based HATs there may be some limitations which may need to be considered. You may need to check what pinout your HATs/pHATs are using. A great resource for this is Pinout.xyz.

Compliance
