“A superb raspberry PI for the price. Exactly what you need for a simple application. This price puts it in easy competition with the arduinos yet you get a full computer with Linux OS and graphics.
Great.”
“If you can get your hands on one, perfect for building into projects due to its low profile and small footprint. e.g. You can solder on right-angle male pins if you wanted to keep the Pi 'flat'. Great price too.”
“Pi Zero is a very small embeddable unit. It is absolutely not for beginners but advanced users may get much of it. Lower power consumption and smallest footprint are it’s best features. It runs Java code with an ease. Lack of dedicated monitor/camera connectors may be a problem for some but for headless options it works great.”
