“Great device!!! I’m a beginner with Raspberry Pi but found the install process quite easy. Installed the headless version of the OS running pihole and the controller for my Ubiquiti UniFi network so far. No doubt many more interesting projects to come.”
“Works fine out of the box. It's not as nippy as the 8GB version, which I also have. Slowish if used for Web surfing, but you get what you pay for. However it works just as well as the 8GB version when used with my Picotech Dr Daq and 1020 series ADC data logging systems and handles the real time graphing and computational tasks well. Buying it has released my 8GB version for more interesting projects. It did have one advantage for me over the 8GB version in that it gave me the opportunity to install the earlier Aduino IDE version 1.8 which has the Serial plotter option. The version 2.0 IDE which I have on my 8GB pi doesn't yet have the plotter option which is a serious omission if you want to plot real time data. If you just want the 4GB version for project work it will be absolutely fine and you will love it. If you want it for use as a surrogate desktop PC it will be disappointing.”
