CanaKit Raspberry Pi 4 4GB Kit - Best Overall
The CanaKit Pi 4 4GB bundle ships with the proper 3A USB-C power supply, a real heatsink, a fan case, a quality SanDisk Ultra 32GB card, and an HDMI cable. It is the kit I keep recommending and the one I run on my Voron.
Check price on Amazon →I have run OctoPrint and Klipper across half a dozen Pi setups and these five kits give you a printer brain that actually keeps up.
I print a lot. My main workhorse is a Voron 2.4 and I have a Bambu A1 Mini as a backup, and behind both of them sit Raspberry Pi boards running Klipper and OctoPrint. The right Pi kit makes a 3D printer feel like a modern smart device. The wrong kit, or a cheap microSD card, will introduce print failures that you will blame on your printer for months before realizing the Pi was the problem.
The five kits below are the ones I have personally used or stripped for parts. I cared about which actually include the right power supply, real cooling, and a quality SD card or eMMC.

CanaKit Raspberry Pi 4 4GB Kit - Best Overall
The CanaKit Pi 4 4GB bundle ships with the proper 3A USB-C power supply, a real heatsink, a fan case, a quality SanDisk Ultra 32GB card, and an HDMI cable. It is the kit I keep recommending and the one I run on my Voron.
Vilros Raspberry Pi 5 8GB Kit - Most Powerful
The Vilros Pi 5 8GB kit is the answer if you plan to run multiple printers, a Klipper Mainsail dashboard, and a 1080p webcam stream all from one board. Active cooler included, real 27W power brick.
LABISTS Raspberry Pi 4 Starter Kit - Best Value
The LABISTS Pi 4 2GB kit hits the right price for a single OctoPrint setup without a webcam. The 2GB of RAM is enough for OctoPrint and basic timelapse, just not for heavy plugins.
BTT CB1 with Pi CM4 Carrier - Compact Pick
The BigTreeTech CB1 with carrier board mounts directly to certain BTT boards via a header, eliminating the cable mess. Klipper runs natively and the form factor is tiny.
CanaKit Raspberry Pi Zero 2 W Kit - Budget Pick
The Pi Zero 2 W kit is the smallest possible footprint at the cheapest possible price. Fine for OctoPrint without a webcam on a small printer. Not the right call for Klipper.
Quick answers
Pi 4 with 4GB is enough for Klipper on a single printer. Pi 5 is overkill unless you run multiple printers or a webcam stream at 1080p60.
Yes for basic file streaming, but slicing previews and webcam streaming will choke it. Get a Pi 4 if you can budget it.
