Part 4. Final Verdict

We went from unboxing to building and deploying a true internet of things (IoT) project using a Pi Zero and a GrovePi Zero. Let's breakdown the GrovePi Zero experience in terms of usefulness, usability, and affordability.

Usefulness

The GrovePi Zero provides an extremely flexible platform for connecting sensors and various devices via the Grove universe. The applications are endless. The GrovePi really shines in the various IoT project possibilities (e.g. build a web-connected sensor box). Eliminating the need for a breadboard enables practical deployment of projects. Its compact size gives it a big advantage over traditional sized HATs and shields. In terms of usefulness, the GrovePi Zero delivers.

Usefulness: 10/10

Usability

Maker boards are only as good as their software and community support. The GrovePi Zero has an existing Python library for the majority of the available Grove devices. The GrovePi Python library makes scripting extremely easy. There are plenty of great examples at Seeed and various project websites. Prototyping your electronics is about as simple as you can make it with the GrovePi Zero. You simply plug-and-program.

Usability: 10/10

Affordability

The GrovePi Zero misses the mark on price. $28 is simply too expensive compared to other available HATs. The most common use of a GrovePi Zero will be to pair it with a $5 Pi Zero. Even though that $5 becomes $29 by the time you add all of the necessary components to the Pi Zero, paying $28 for an accessory to the Pi Zero just feels wrong. That being said, $28 won't break the bank, and the GrovePi Zero can be an invaluable part of a project.

Affordability: 5/10

Bottom Line

The GrovePi Zero is a fantastic add-on board with unlimited potential. My only major problem with it is its price. If the GrovePi Zero were $15-$17, it would be the must-have accessory for anyone building IoT projects with the Pi Zero.
