“This was my fourth RPi Zero W. It is small linux based computer capable to do a lot of IoT type
things. The product is compact and good quality allowing easy installation. It is not necessarily as powerful as RPi 3 or 4 but can provide web server with database, like SQLite as well as easy integration to external devices either trough USB or GPIO pins.
This RPi Zero W is connected to my CNC's USB port and allowing USB control over WiFi from my desktop computer. Another I have with ePaper display running a data and web server. It
collects different measurement data and provides it both via web interface and ePaper.
The RPi Zero W is nicely priced small computer providing full power of Linux. Totally worth of money.”
“For the price you can't knock this little power house. Even if it is only wifi and bluetooth the gpio is so simple to interface and make cool little projects. Powered by a battery or micro usb. What's not to like?”
