Works exactly as expected, was easy to install the raspberry OS and subsequently the pi signage software which is what I bought it for to drive a display as a digital sign for commercial application. Power consumption was low enough that I could power it from the USB port on the back of the TV I used for the digital sign. Performance was just good enough using the Pisignage software using static image files but was a bit sluggish with full HD videos which was not terribly surprising but still good enough.

A couple of relatively minor complaints:

First I really wish it used a USB C connector for one or both of the USB ports especially the DC power input. I really hate micro USB and wish all manufacturers building products with micro USB with switch to USB C.

Secondly, I hate the mini HDMI type connector wish they had used either a full-size HDMI or even a micro HDMI which is much more popular today.

I understand both of these choices are probably based on the original version of the board and changing to USB C or micro HDMI or full HDMI would render it incompatible with cases built for the original. Still would love to see both of these changes.

Of course the elephant in the room is that the availability of these boards is still really poor which means that I can't really deploy this as part of an electronic sign solution that I plan to sell too many of my customers. So it was okay as a test platform and I guess just need to wait for the covid-19 fueled semiconductor and Logistics bottlenecks to get worked out over time which is not really the fault of the raspberry Foundation but is industry wide. Hoping this situation gets worked out soon.

Overall highly recommend this board for any Raspberry Pi application where you don't need a huge amount of CPU performance or lots of memory

The main reason I got this was to test if .net core 6 compiled for ARM would run on this board, and it works! (The earlier versions of the Pi Zero did not have the right ARM chip)

Faster is better. The previous Pi Zeros were a little slow. This one is a great improvement!

This new Pi Zero 2 is a major improvement in speed over it's previous version, you can almost smoothly surf the web with it. I am building an environmental chamber controller out of this one, and so far no issues, a great little micro controller.

I use the Pi Zero for a headless, amateur radio application. The Pi Zero W took approximately 2.5 - 3 minutes to fully boot up and be available. The new Pi Zero 2 W boots approximately 4 times faster! It usually only takes around 30 second for it to boot up and be fully functioning.

I've also not noticed much increase in heat since my application does not have a GUI.

I purchased 2 the first one was DOA I tried to reported and was told to go to the forum, to date It does not work it overheats

Paying twice the cost of a First Class package for an item that could also go into a First Class letter is kiling consumers.

Appreciated Sparkfun’s purchase policy for this harder to get product.

Bought this to get back into tinkering with RPis. Love the little form factor and how little energy it uses. Not the most powerful of Pi's but for what I’ve been using it for, it’s great!

Finally I got this board from sparkfun for best price, while local seller in my country charge for about 4x times more. it is much faster than previous zero W

I had issues with the USB port. But I was able to resolve on the forums by confusing a USB hat

The small size and having the processing power to run octopi/octoprint to control my Creality printer via wifi and usb is perfect. The fact that it also supports a inexpensive pi cam even better. Shipping was fast and like all past orders from Sparkfun I’ve made, very pleased.

It's overkill, I know, but for Klipper it works great regardless of which Creality 3d printer it's attached. Thanks, Sparkfun, for providing inventory in such a tight market!

The best thing was the back order fulfillment - this was the best thing for me, I wondered if this would ever be done but it was it was great!!

I love all of the raspberry Pi's, and the Zero 2 W is a great upgrade to the original Zero. It's much faster and make a great board for home projects. I just sad they are so hard to get. This is the first one I've been able to purchase in a few years.

I'm very excited to start next year's Halloween candy machine with this unit at the heart of the project.

The previous three machines have used a Raspberry Pi 3B which might be getting long in the tooth.

I'm going to leave that 2023 Gronk droid version intact and start a whole new build.

Much snappier than the original Pi Zero W. Was pleased to see Sparkfun had these in stock again. My only complaint is the limited purchase quantity made it very difficult to justify the shipping expense.

Got it to add networking and camera support to my Prusa i3 MK3S 3D-printer, and it works quite well. Now I can print without having to deal with an SD card.

I replaced a Raspberry Pi Zero W with this and the performance improvement is noticeable. I was able to connect a Pi Camera Module v2 with no problem, and it fit in the AdaFruit case. Amazing how well this little machine works for what it costs.

I thought my new RPi Zero 2 W was defective. Tried several µSDs with fresh installs, but attempts to "apt-get update" from the initial installs failed repeatedly. But those same µSDs updated just fine on a RPi 3B+.

Sparkfun graciously sent me a replacement. But it failed in the same way.

With a bit more experimenting, I found that the default for swap space was now 100MB (!) on new installs, rather than the former twice physical memory (which would have been ~1GB). Any significant activity on a newly-installed RPi Zero 2 W failed because of lack of swap space but succeeded on a 1GB RPi because swap space wasn't needed.

So if you get a new RPi Zero 2 W, edit /etc/dphys-swapfile to either set CONF_SWAPSIZE=1000 or to comment it out and set CONF_SWAPFACTOR=2 (i.e., uncomment it).

Incredible horsepower gain over a Raspberry Pi Zero W. However it does not have enough memory to utilize it in many applications. It also typically comes at a premiun which almost doubles the cost.

I bought the Pi Zero 2 W expecting it to be a higher-performance no-brainer drop-in replacement for the Pi Zero W(s) I’m using now, but it has serious problems connecting to secured Wi-Fi networks when using the standard Pi OS images. Do a web search and you’ll learn there’s maybe a 50-50 chance it’ll fail with your AP like it does with mine. All my other Pi models (and non-Pi devices as well) work fine. I’ve since bought another Pi Zero 2 W from another supplier to compare, but it fails in the same way, and I’ve returned it. The problem seems to be software/firmware, not hardware, so maybe it’ll eventually get fixed, but for now, I recommend you avoid this product.

P.S. I’ve posted to the forum to initiate a return/refund, but there’s been no response from SF. Shipping costs nearly double the cost of this board anyway, so I’m probably just stuck with this lemon.

It is slow, but serviceble. I wish that it had more ram. It does not like going online for very long, but for some simple projects it does a good job.

I have a few other Pi 3B/3B+ models and have thoroughly enjoyed them. However, I like the smaller form-factor which makes it great for projects where weight/size are an issue. With 512M of RAM, there is plenty of room for programming, but you may think twice before using it as a full-desktop. It runs the PiOS desktop just fine, but if you want to launch a full, memory-hungry, browser (a chromium variant or firefox), it will be quite slow at times. But, I didn't buy it to surf the web on.

A quick overclock tweak with over_voltage=4, arm_freq=1300, core_freq=500 in /boot/config.txt brings an extra bit of pep to the Zero 2 W while still staying well within the warranty limits. (if you experience a lockup at 1300, back it down to 1200 and try again) The board, even with the overclock, runs about 4 degrees cooler than the Pi3B+ in the official case.

The microSD flash, Install and WiFi config was a breeze. Since I access this thing over ssh, I simply disabled booting the desktop and boot to console without auto-login and just use it headless.

If you are used to the Armv6 assembly on the 32-bit OS, be aware that the 64-bit os is Armv8 (Aarch64), so you will learn 64-bit Arm assembly (which is actually quite nice when you make friends with the removal of the condition-codes that were quite convenient in 32-bit Arm)

Note (Nit) the only drawback with the design pops up when you go to manually solder in the 40-pin header. Note, there are no traditional solder-pads around the pin-header holes -- just tiny copper rings. This makes it difficult to solder. Make sure you have a fine-point on your soldering iron so you can contact the ring and header-pin at the same time and use an 0.8mm or 0.6mm diameter solder. Things go fine then, just take your time and don't be afraid to redo a pin if needed.

(tip: solder a couple of pins on each row to hold the pin-header in place and then work the inside row before the outside row, generally skipping every-other pin as you work down the line to prevent localized heat build-up)

Don't forget your Goto micro-USB adapter and HDMI-microHDMI adapter and good power-supply (there are great kits that have all three and a case for about $10) Have fun!

WiFi connection to the router is non-consistent, unfortunately. In about 12 hours WiFi access to the board becomes unavailable until board hard reset. Hope board software will be fixed soon.

This is the smallest most powerful device with WIFI and Bluetooth. Low power and potential for fast startups. I'm loving it.

It's running Octoprint for my Ender 3 v2 like a champ! My only complaint is I could only buy one. Don't question if you should buy one for your project, just do it!

My great Nephew got the bug. I am the nerd in the family and have been playing with Pi since they first came out. He got a Zero, I ordered one so I could work with him. I have it on a MAZE Mouse I designed and we are building them somewhat in parallel 500 miles apart. I am retired but think I might get a few more to build widgets with. Great little product, but it is not a stand alone. a person needs cables, power supply, keyboard, monitor, and enough parts in a kit or otherwise to do things with it. Most of the extra stuff can be used on multiple project so is a one time expense if you get into building widgets with the various Pi.

Loved the pi zero 2. Sparkfun shipped it and priced it right!
