HATs are incredible add-ons to the Raspberry Pi that increase its functionality in a huge number of ways – from added sensors and inputs for fun projects, to practical applications in business and enterprise.

Here are our picks for the 10 best Raspberry Pi HATs:

Sense HAT: Space-faring sensor

Used in the Astro Pi devices up on the International Space Station, this cool Sense HAT (£32 / $40) has an 8×8 pixel display, environmental sensors, accelerometer, and a little joystick. There’s loads of great Raspberry Pi resources that use it as well.

GFX HAT: Display and inputs

We really like the GFX HAT (£22 / $23) – not only is it a very nice display that is easy to program for, it also has a series of (capacitive touch) buttons. It’s amazing for practical projects or basically any Pi that’s turned on a lot

PoE HAT: Power over Ethernet

The Raspberry Pi is very popular in enterprise settings, and the PoE HAT (£18 / $20) allows for a more efficient way to add Pi boards to a system. With PXE boot and power from the Ethernet port, you can do a lot with a 3B+.

PaPiRus HAT: E-ink display

You can make anything look 20% classier with a PaPiRus HAT e-ink display (£41 / $54). Trust us, we’ve got the science to back it up. It’s very low-power, depending on usage, and looks great even in bright sunlight.

HiFiBerry DAC+ DSP: Powerful audio amplifier

This powerful HiFiBerry DAC + DSP (£60 / $78) includes a DSP (digital signal processor) which allows for full control of the way your audio is output from the Pi. The folks at HiFiBerry call it a ‘DAC on steroids’.

TV HAT: Must-see TV

Tune into digital TV in Europe with this excellent TV HAT (£20 / $26) which then lets you stream the signal around your house. It’s the perfect complement to a Kodi box, and it sits nicely on top of a Pi Zero.
