I have had this product for about a week, and am very happy with my experience so far.Waveshare provides a wiki which contains two versions of downloadable code for the Raspberry Pi Pico and Pico W. Both versions can be installed as-is, and both can be customized. The 2 versions do not implement the identical functions.The microPython version does not implement the alarms or the stopwatch, but does support Wifi, and NTP synchronization. The recommended IDE for the microPython version is Thonny, and instructions are shown in the wiki for its installation. I found this version to be very easy to install.The c implementation supports all of the advertised features, but does not support Wifi or NTP. A pre-built uf2 file is provided in the downloadable zip file, for those who do not want to compile their own version. The recommended IDE for the c version is Visual Studio Code. The documentation on the wiki is adequate for implementing the c version, but it does take a careful reading, and I did struggle with the installation and compilation.For those that are comfortable with Visual Studio Code, or want to easily add additional functionality, there is an alternative implementation available. Search for PicoClockGreenEasy, for a github page and video. The source code on the github is not based on the Waveshare example, but supports all of the described functionality. IMHO, it is a pretty impressive implementation. There is a pre-built uf2 file on github, which can be installed using the normal BootSel process. The implementation supports Wifi and NTP synchronization, but compilation is required to implement those functions. The author is investigating the use of GPS for time synchronization. The use of the clock, and the code itself are well-documented, and I have already been able to customize it.I am a beginning programmer, and have been able to customize all three versions of the code described above, as well as install the pre-built versions. If you are interested in learning about the Pico and Pico W, and want more than a basic demo, this clock is a very good choice.

The hardware the great. This has been running for several months without any issues. The documentation for C and example code is far more robust that Python. I bought this as a Python project and it was a good learning experience at the time. The Python repositories on GitHub are a bit stagnant, but allow you to make a functional clock without much fuss.
