The New Raspberry Pi Zero 2 Will Blow Your Mind!

hey guys what is going on it's don here from nova spirit tech and i'm super excited to show you this brand new product from raspberry pi which is the raspberry pi zero two w so let's get started [Music] now first i do want to thank raspberry pi for sending this over to me for review and there is a lot to go over so let's begin now first glance the raspberry pi zero two w which i'm just going to call zero two is the same exact form factor as the predecessor or zero one they did not change any of the ports and kept everything the same size you will still have the micro usb for power and the other one for otg as well as the mini hdmi and then the sd card is still in the same position as well as the csi interface gpio layout is exactly the same so as far as the design wise nothing has changed now if you take a look at the back the pinouts to the raspberry pi zero first version is slightly different now you could still use the cases that you have that requires the otg or the power pins they are still in the same spot but they added the ability to see the ddr 1.2 volt and as well as the cpu 1.8 volt or not the cpu but one cool thing that they did add is the ability to use composite video mode so that's also a pin out on the bottom one of the things i wish they did have on the original raspberry pi zero because i needed to use it for certain projects they also labeled everything so it's a lot easier to read compared to the first version so i like that as well now hardware wise that's where everything has been changed and this one has quad core running at 1 gigahertz the only downside to this board is that it's only got 512 megs of ram and i'll talk more about that in a little bit because i got a solution for you guys as far as the wi-fi goes it's actually using a similar module to what you would get on the raspberry pi 4 which is great because i am getting way much better reception now as far as powering this guy on idle it runs around 0.1 amp at 5 volts that means it's about 600 watts or 700 watts right around that area similar to what you would get from the raspberry pi one just a little bit more and at full load i do see it go up to 0.6 amps as right now the only operating system i have tested is raspberry pi os and i have tried to plug in other operating systems but without the kernel for the new cpu those operating systems did not work i do want to test a lot of different operating systems on this guy because the quad core is actually a pretty good cpu on this now jumping into the benchmarks i'm going to show you the comparisons between this one and the first version and you can see it's heaps better i mean it's quad core compared to single even though it's at the same speed but what surprises me the most here i'm going to pop in raspberry pi 4 and raspberry pi 3 and as you can see this benchmark is slightly faster than the raspberry pi 3. and i've tested this a couple of times just to make sure and yes every time the cpu even though it's slower than the raspberry pi 3 at 1.2 and this is at 1 it still does slightly faster benchmarks now the whole downside about this raspberry pi when i was testing it is because of the 512 megs of ram with the lack there of ram you have tons of issue running any heavy applications especially just trying to run a browser and running five seconds of a video it will crash an entire system now there are two ways to fix this one which is not a very clever solution which is enabling swap you can enable swap to the sd card get maybe another gig of ram anytime you try to run something heavy it has something to fall back to or two you could follow my github and actually install zram i've updated script recently so now it's just the install process all you have to do is go into git clone github nova spirit rpi underscore zram download that change into that directory and just run the install script that will actually install a service into the raspberry pi which will run the script that will calculate how much ram that you should be using per core per compression so basically zram is compressed ram it's going to take the four cores which now that we have and compress the ram to give you swap and by doing that you will now get about 1.7 gigs of ram extra in swap which now allows you to play videos or anything that requires a little bit more ram in our case i was just playing a youtube video it did okay it's not the greatest it did have some dropped frames especially when i was running 1080 videos but otherwise it was able to run it after you put some swap into it as far as the wi-fi goes i compared this directly to the raspberry pi zero and at the same exact position running the same exact wi-fi network i am seeing an increase of signal on this newer board so compared to the old one you do get a better signal now i also took my time and i overclocked the cpu and yes you can actually overclock this one now i was able to get it a maximum of 1.3 gigahertz with over voltage of 6 and it ran stable i did try 1.4 gigahertz and then that's where it started crashing so i didn't do increments like you know 3.5 or 3.75 i just literally went 100 megahertz a piece and then i stopped at 400 and then i rolled back to 300 and then that's where it was stable and at 1.3 gigahertz that's a 30 increase in speed for the raspberry pi zero and this thing actually works pretty well it boots up relatively fast compared to the predecessor of raspberry pi zero and i think it's a slightly faster than raspberry pi 3 when it's booting up in all honesty i use my raspberry pi 3 for a lot of projects like octopi or cnc machines and stuff i think i might just want to replace it with the raspberry pi zero now on top of that how much is this board going to cost all in all 15 i'll leave a link to everything we talked about down in the description below i'm not exactly sure where you could purchase it yet but probably their regular distributors like pie hut and all this other places but yeah it's going to be only 15 in conclusion compared to the raspberry pi zero this is a huge step up because the main thing that was lacking on the raspberry pi zero was the cpu you weren't able to process much information through the raspberry pi zero especially trying to run something a little bit heavier than its normal task it'll either lag a lot or just have issues running it now i do use my raspberry pi zero a lot i have it for raspberry pi hub which i'll leave a link here i run it for kvm which i'll leave a link here here as well and then i have a few other projects that i run the raspberry pi zero for so basically this new board will be able to do all those tasks but better because i do run into issues with the board being too slow especially when you're trying to turn it into a little webcam it definitely lacks their inpower trying to force feed the information to be encoded and everything while the ram is low it's not really an issue if you use the compressed ram method that i just showed you you should be able to run all the programs that you need anyway i am glad that they moved over to the new one because the old one was starting to get outdated it was starting to get to a point where there was a lot of things i wouldn't use because it was too slow anyway that is it for me if you guys have any questions about this brand new raspberry pi zero or anything that you want me to test on the raspberry pi zero two let me know down in the comments below and if you guys are new to this channel consider subscribing and also hitting
