The SunFounder Raspberry Pi Pico W Ultimate Starter Kit is another great STEM type project kit from SunFounder. I have been buying and using SunFounder products for several years now and the high quality of this kit is what I have come to expect from them. A good way to know the overall quality of a project kit like this is to look at some of the more basic items, such as the resistors and capacitors. The components included with the kit are high quality and the stated values and actual values are dead on. As with any electronics kit, there are bound to be some that come with defective components, that is to be expected regardless of the brand or manufacturer. So far, I have not had that experience with any of the kits and products I have gotten from SunFounder.This kit is good for the beginner (they will want to use the online tutorials and other online resources if they are brand new to Arduino and Raspberry Pi and/or programming languages like C++, MicroPython, etc.) to the advanced programmers looking to have some fun. As this is a multi-project kit that can be used to build/learn quite a few things, I have not had an opportunity to use everything included, and there is a lot of stuff included! What I can speak to is the quality of the kit and some of the projects included in the kit.I have several SunFounder Arduino boards, as well as multiple kits and Ultimate kits and the components that have come in each one is good quality and does what it is supposed to do. I know there are some reviewers on this kit and other SunFounder kits that mention a component or board that is DOA and as I mentioned, it is going to happen with electronic kits. I have personally never had any issues with any of the SunFounder Arduino boards, sensors, etc. though I have experienced with other electronics over the years.This kit combines the Raspberry Pi Pico W, which is the wireless version of the Pico and has a single-band 2.4GHz wireless interface (802.11n) built into the board. That means some of the projects involve one of the faster growing segments in technology these days, IoT (Internet of Things)! By having projects in several different programming languages, you can see which one works better for you. If you or the recipient of this kit is brand new, I would suggest starting with Piper Make which uses a GUI (Graphical User Interface) to code and then moving on to either MicroPython or C++ (which is used in many devices such as 3D printers).If you are interested in learning to code, using micro-controllers and controllers such as the Raspberry Pi Pico or its bigger sibling, the ever-popular Raspberry Pi, this is a great kit that is not only fun but also teaching STEM subjects which are only going to become more and more prevalent and important. I would also recommend looking at some of the other kits that SunFounder has, especially as a gift to any child that has shown or expressed an interest in STEM, coding, Engineering, etc., as a way of fostering that interest and curiosity. Technology, computers, IoT and so forth are only going to become more and more important and part of our everyday lives and we will need more coders, programmers, Engineers, etc. I absolutely recommend the SunFounder Raspberry Pi Pico W Ultimate Starter Kit!
